9 tony 209 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
10     all previous copies of the IBX source code tree before installing this release.
12     The IBX packages used by most users have not changed, with one exception. The
13     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
14     to use the IBServices unit in your applications, please add the iblegacyServices
15     to the list of dependencies. To do this, open the Project Inspector and select
16     Add->New Requirement and select "ibLegacyServices" from the list of available
17     packages.
19     1. New unit IBXServices. The IBXServices unit is a re-architectured update of
20     the IBServices unit providing what is intended to be a clearer and easier to
21     use set of IB Services components. See Chapter 10 of the IBX User Guide for
22     more information and the guide to "Firebird Service Management Using IBX".
23     As indicated above, the legacy services components are still available and
24     provided in a separate package. There is no need to update working applications
25     using the older versions except for an additional package dependency.
27     2. The IBX packages and source code tree have been re-organised in an attempt to
28     finally get rid of the "duplicate ppu" warnings. This re-organisation should
29     not affect existing users. Section 2.3 of the IBX User Guide describes the
30     new set of IBX packages.
32     3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
33     updated to use the new Services API components.
35     4. The iblocal package has been updated to use the new Services API components.
37     5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
38     TIBXSecurityService. It had been wrongly classified in the previous version
39     as a per database configuration item. It is global to a server and hence
40     correctly positioned as part of the Security Package. In the DBAdmin example,
41     the setting has moved to the mappings page.
43     6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
44     are ignored.
46     7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
47     closed before the database is dropped. Before and After Disconnect event handlers
48     are also fired.
50     8. TIBTransaction: OnStartTransaction event now fires every time the transaction
51     is started and not just the first time.
53     9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
54     depenendency with comp type.
56     10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
58     11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
59     then this is recognised and not ignored.
61     12. TIBDataSet, TIBQuery, TIBTable: additions:
62     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
63     function GetPerfStatistics(var stats: TPerfCounters): boolean;
64     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
66     GetRowsAffected returns the affected row counts from the last insert/update/delete
67     if EnableStatistics = true then GetPerfStatistics returns the current stats
68     counters for the select query. Note: stats accumulate after each fetch from
69     the database. To get total query cost after open, call the "Last" method
70     and then GetPerfStatistics.
72     See ibx/examples/consolemode for an example of the use of GetPerfStatistics
74     13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
75     in parenthesises.
77     14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
78     SQL identifiers are always delimited by double quotes. If false, then they are
79     only delimited if the identifier is a reserved word, contains lower case or special
80     characters. Set this property to true to retain previous behaviour.
82     15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
83     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
85     16. TIBDataSet, TIBQuery, TIBTable: addition:
86     property MasterDetailDelay: integer {defaults to zero}
88     When non-zero and the dataset is a detail table referencing a master table
89     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
90     then a synchronisation delay is added (in milliseconds) between the master
91     row changing and the detail dataset being re-opened. If the master dataset
92     is scrolled before the delay expires then the delay is reset. This can be used
93     to avoid performance overheads when scrolling through a large master dataset.
95     Note: uses fptimer and hence requires a thread manager. Under Linux the
96     chreads unit must be included in your project. TTimer is not used in order
97 tony 213 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
98 tony 209
99     17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
100     with Extract Option eoDatabase.
102     18. TIBLookupComboEditBox: Workaround added for
103 tony 225 When a deLayoutChanged event is reported on the ListSource dataset, the
104 tony 209 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
105     relationship with the control's datasource (master).
107 tony 221 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
109 tony 226 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
110 tony 221 stubs. Pedantic fix really, as procedures output in dependency order anyway.
112 tony 226 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
113 tony 221 DDL (Firebird 3 and later only).
115 tony 225 22. TIBLookupComboBox Autocomplete Fixes:
116     i. Only appended text is now selected after autocomplete.
117     ii. Uppercase keys no longer ignored for autocomplete.
118     iii. Retain Prefix case is now honoured correctly.
119     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
120     before autocomplete performed. i.e. behaviour now the same as when
121     no DataSource assigned.
123 tony 226 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
124 tony 225 between SQL statements.
126     24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
127     ObjectNames are converted to upper case before matching against metadata object
128     names, unless the objectname is delimited by double quotes, in which case, the
129     double quotes are removed and the remaining string is used (unmodified) to match
130     against the metadata object name.
132     If true then the ObjectName is used as is without modification and matched
133     against the metadata object name. No attempt is made to remove double quotes.
135 tony 226 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
136     with eoTrigger, these extract types can be used to select only Database Triggers,
137     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
139 tony 227 26. TIBXScript: If an exception occurs during the processing of a statement, the
140     statement separate character is now reset to the default (';').
142 tony 229 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
144     28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
145     a commit or reconnect statement and instead activated only when next SQL statement
146     is executed.
148     29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
150     30. TIBXScript: case insensitive regex now used when matching statements instead of
151     converting statement to upper case.
153     31. TIBExtract: metadata comments now supported. New published property
154     IncludeMetaDataComments (default true). If true then metadata comments included
155     in extracted DDL. New Extract Object member eoComments. This may be used with
156     ExtractObject method to list all metadata comments.
158     32. TIBExtract: ListObjectNames method added.
160 tony 231 33. Updated Database component editor to support additional connection string
161     types.
163 tony 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
167 tony 151 RELEASE.
171 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
172 tony 101
173     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
174     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
175 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
176     column values. Values returned as a result of executing an Insert or Update statement
177     replace existing values in the current row for each corresponding column.
178 tony 101
179 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
180     an automatic row refresh was performed after an insert or update query had been processed,
181     irrespective of the setting of the "ForcedUpdates" property. This has changed such
182     that an automatic refresh is no longer performed if an insert or update query contains
183     a returning clause that updates one or more fields on the current row. A full row
184     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
185     field values and the select query contains read only fields. Use of Insert/update
186 tony 123 returning should be significantly more efficient than executing a refresh query.
187 tony 107
188     This behaviour change is intended to be backwards compatible and there should be no need to change
189     existing programs, other than to improve performance by using the new capability.
191 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
192     they are called when the dataset row is being deleted, there is no value in
193     updating the current record from the query result. Instead, a new event handler
194     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
195     an OnDeleteReturning event handler is provided then it is called with the IResults returned
196     by the query. The event handler can then interrogate the query results and
197     perform whatever action is necessary. For example to confirm, to the user,
198     the deletion of a row with the returned values.
200     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
201 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
202     illustrate the computation of the employee Full Name on update.
204 tony 118 5. TIBTable: The GeneratorField property is now published.
205 tony 107
206 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
207 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
208     be inserted. A RETURNING clause is added to the insert statement to return the value of
209     each Identity column after the insert is executed.
211 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
212 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
213     Insert..Returning clause.
214 tony 104
215 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
216 tony 107 a new value is generated.
217 tony 104
218 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
219 tony 107
220 tony 118 10. Property editors will now sync table name to a System Table when "Include System
221     Tables" is selected and the query is for a System Table.
222 tony 105
223 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
224 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
225     to TDateTime (the conversion to milliseconds is the default TDataset approach).
226 tony 105
227 tony 118 12. Property Editors handling of Stored Procedures.
228 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
229     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
230     query).
231     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
232 tony 106
233 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
234 tony 107 can be used to select a package. If non-empty, the stored procedure name is
235     expected to be a stored procedure defined in the specified package and the
236     generated SQL will be as required for a stored procedure located in a package.
238 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
239 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
240     which a stored procedure can be selected. With no package name selected, non-package
241     stored procedures are listed.
243 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
244 tony 109 for password on reconnect.
245 tony 107
246 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
247 tony 118 and character set name.
248 tony 109
249 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
250     DB info lookups"
252 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
253 tony 118
254 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
255 tony 118
256 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
257     parameters. This stops an exception being raised when the field cannot be
258     located in the record buffer.
259 tony 127
260 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
261     is a System Table.
262 tony 139
263 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
264 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
265 tony 141
266 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
267     add the SPB item isc_spb_expected_db. This names a database using
268     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
269     database. examples/services re-written to illustrate use of "expected_db".
270 tony 141
271 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
272     This avoids truncated backups when the server returns a timeout (busy) response.
274     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
276     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
277     databasenames. These are respectively expanded to the local system's temp directory
278 tony 150 (including trailing delimiter) or to a prescribed data directory (including
279 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
280     in the user's home directory. The hidden directory name is either the string returned
281     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
282     Under Windows, the directory is the same as the Data Directory as decribed
283     above but instead prefixed by the User's application data path. These may be
284 tony 150 used to improve application portability for Personal Databases.
285 tony 143
286     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
287     this has not worked for a long time and is not useful either. FieldDefs should be
288     managed using the Fields Editor as with any other dataset. To access the fields
289     editor for a TIBTable component, double click on the component. The fields editor
290     is then displayed.
292     28. TIBDatabaseInfo: new properties/function
293     * DateDBCreated (returns date/time database created)
294     * TransactionCount (returns no. of active transactions)
295     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
296     * PagesFree (Firebird 3 or later)
297     * PagesUsed (Firebird 3 or later)
298     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
299     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
301     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
303     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
305     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
306     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
308     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
309     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
310     firing during backup and restore.
312     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
313     for verbose output using the new property "StatisticsRequested".
314     see
316     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
318     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
319     palette. This uses the online validation feature added in Firebird 2.5. The
320     services's properties enable inclusion/exclusion of tables and indexes using
321     regular expressions. See.
324     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
325     option on a database.
327     37. TIBCustomService: Assign method implemented to allow copying of service login
328     context between service API components. "Detach" method now only detaches
329     service when last reference to the service interface detaches. Tidy up of
330     code for SetActive and Attach methods including password hiding.
332 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
333 tony 143 and used to determine the auth method and protocol used for the connection.
335     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
336     a Create Database Statement generated by IBX.
338     40. All IBServices now have an additional published property "PortNo". This may
339     be set to a non-standard port number when necessary. If zero then the default
340     port number is used.
342     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
343     and not just the mouse.
345     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
347     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
348     image index and selected image index for each node to be set from a database field.
350     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
351     then database schema includes grants to all users. If not present then the
352     only user grants included are those to User PUBLIC.
354     45. TIBTreeView: performance improvement. When expanding include both expanded node
355     and child nodes in dataset.
358 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
359 tony 56
360     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
361     changes.
363 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
364     Bug could result in truncated multi-byte character set values.
366 tony 60 3. Changes consequential on moving fbintf character set utility functions from
367     IFirebirdAPI to IAttachment.
369 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
371 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
372     results in autocomplete ignoring prefix text.
374 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
375     entering a new name into the text box.
377 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
378     Firebird rather than recomputing it.
380 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
381     screen centre. Previously some were "poDesigned" which may be inappropriate
382     for multi monitor desktops.
384 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
386     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
387     a transaction and always reset the object.
389     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
391     13. TIBXScript: Allow for override of database filename in Create Database statements.
393     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
394     to a gbak format archive.
396     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
398     16. IBLocaldb: Drop database if error creating an empty database.
400     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
401     unless selected node not in current dataset.
403     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
404     to TIBCustomService, and IBlocalDB code tidy up.
406     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
407     behaviour due to uninitialised variable.
409     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
410     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
412     21. IBSQL: When Database changed ensure that all resources are freed.
414     22. IBCustomDataset: When database changed ensure that queries an unprepared.
416 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
417     * Line Wrap on SQL Token boundaries (on user command)
418     * auto-complete table names in drop down list of table names
419     * Double click on tablename or field name adds to SQL text
420 tony 80
421     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
423     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
424     TVariantArray. Seems to avoid memory corruption in Windows (probably a
425     workaround for a problem in fpc 3.0.4 win64).
427     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
429 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
431 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
432 tony 49
433 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
434 tony 49 include remote system name.
436     2. TIBExtract: No longer include comment header and COMMIT statement for empty
437     tables when data included in output.
439     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
440     and timing information to be written to stdout. This may be used to locate
441     performance bottlenecks.
443     4. SQLParser: only call "OnChanging" event handler when value is different.
445     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
447 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
448     that BindFields is called when the query is next activated. Avoids FieldName
449     not found error.
451 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
452     purpose and allows the programmer to define any action they want for Update, Insert
453     or Delete. This may be complex SQL (similar to a Trigger), application specific
454     filtering of updates, or use of statements such as Grant or Revoke instead of
455     normal DML. See User Manual for more information.

459 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
460 tony 45
461 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
463     3. TIBExtract: data formatted as Charset set "octets" is now output using
464     hexadecimal notation.
466     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
467     using a simple XML format.
469     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
470     grants to these objects.
472     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
473     dependency problems restoring complex databases.
475     7. TIBXScript: This component has been restructured to allow for the processing of
476     embedded XML in INSERT statements and to support interactive sources in addition
477     to non-interactive data sources such as files.
479     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
481     9. TIBXScript: ISQL compatiable Set statements are now supported:
483     SET TERM
485     SET BAIL
486     SET ECHO
487     SET COUNT
488     SET STATS
489     SET NAMES <character set>
491     10. IBVersion unit added to hold current IBX Version Number information.
493     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
494     and domain definitions.
496     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
497     fully supported.
499     13. TIBExtract: when a database dump includes data, the generator values are now also set.
501     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
503     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
505 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
506 tony 45 upgrading to IBX2.
508     1. Size property of TIBStringField is now the width in characters of the field
509     and not the byte length. This applies only to multi-byte character sets such
510     as UTF8. The original approach aligned with TStringField. However, the TStringField
511     code is not recognised as a bug and hence this change to align the behaviour.
512     The TStringField change is expected in fpc 3.2.0.
514     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
515     true (default) then Size property value saved in the lfm is ignored. Size is
516     always set from the dynamic information read from the database. It is unclear
517     why anyone would want to override this and set Size to false.
519     3. ibxscript: should now handle correctly a Case..End statement within a procedure
520     block.
522     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
523     exist when an attempt is made to connect to it (run time only) then an attempt
524     is made to create the database.
526     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
527     has been successfully created as a result of a call to CreateDatabase or when
528     creating a database after it was found not to exist.
530     6. DBControlGrid: a race condition could result in the wrong row image being
531     written to the cache. This has been avoided by a trip round the message
532     loop before rendering the row image.
534     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
535     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
536     known to risk corrupt rendering of row images when the control is first
537     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
538     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
540     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
541     a TDateEdit control located on an editor panel.
543     9. TIBExtract: brought up-to-date plus many bug fixes.
545     10. DBControlGrid: Removed memory leak when updating rows.
547     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
549 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
551     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
552     when target codepage is CP_NONE. This is a workaround for
555     2. DBLog option removed from TIBStatisticalService - not supported by server
556     since Firebird 1.5.
558     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
559     similar.
561     4. IBCodePage: updated mapping between codepages and character id.
563     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
564     Firebird. Character sets with a char width of two are not UTF16.
566     6. Strings received from the database are now always transliterated into UTF8
567     regardless of the database character set or connection character set. This
568     is for compatibility with the LCL.
570 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
571 tony 41
572     1. IBBlob: Defer reading of blob until read method called. This avoids having to
573     read in an entire blob just to get the size of the blob. General performance
574     improvement when opening datasets containing blobs.
576     2. Clearing a Blob now sets the corresponding field's modified flag.
578     3. IBLookupCombo: When not performing auto-complete, original query sort order
579     is now used.
581     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
582     determined.
584     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
586     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
587     lazarus 1.6.0
589     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
590     compilation error.
592 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
594     1. No character set specified for connection: when a text blob is retrieved, the
595     character set is determined by looking up the native character set using then
596     Firebird API. Otherwise a text mode blob is assumed to have the same character
597     set as the connection.
599     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
600     for Login Dialog returing a change to the database path.
602     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
603     to be changed from that given in the TIBDatabase/TIBServer component and for the
604     entered value to be saved on a project specific basis (design time only).
606     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
607     column fieldname. If they are the same then it is acts as a look up for the KeyValue
608     Otherwise, it sets the column text to the selected ListField Value.
610     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
611     column width.
613     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
614     and a case insensitive search is requested.
616     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
617     or column ListSource.
619     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
620     unprepare) when closing and the text has not changed.
622     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
623     Less likely to cause a cursor re-use error on Windows.
625     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
626     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
628     11. TIBTreeView: Guard against nil destination on record changed
630     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
631     string type with the code page set to reflect the returned field encoding after
632     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
633     earlier versions.
635     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
636     will now result in transliteration to the code page specified for the Firebird driver
637     if the assigned string has a different code page. FPC 3.0.0 onwards only.
639     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
640     is ignored and the lc_ctype value, when the database is opened, is set to align with
641     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
642     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
643     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
644     the GETACP is used to determine the Windows code page.
646     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
647     name used as the lc_ctype when the database was opened. Only valid while the
648     Database is connected.
650     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
651     id that corresponds to the DefaultCharSetName.
653 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
655     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
656     path is given and database attach fails due to access permission issues on the
657     temp directory or security database, then the attach is retried with "localhost:"
658     prefixing the databasename. This should avoid problems when the database has to
659     be accessed by a local (e.g. classic) server and libfbembed is used.
661     2. Windows: revised search order for Firebird DLL:
662     i. The Firebird Embedded Server in the application Directory.
663     ii. If the FIREBIRD environment variable is set then the directory this
664     points to is searched for the FB Client DLL and then then underlying
665     "bin" directory.
666     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
667     is used to locate the Firebird installation directory and the underlying
668     "bin" directory is searched for the FB Client DLL.
669     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
670     are searched for the FB Client DLL.
671     v. The PATH Environment variable is used to search for the FB Client DLL.
672     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
674     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
675     See doc/readme.scriptengine and example applications.
677     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
678     simplify the use of the embedded firebird server on both Linux and Windows platforms.
679     See dpc/readme.localdatabase and example applications.
681     5. IBDynamicGrid: Reordering on column header click should now also work for
682     dynamic columns.
684     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
685     between incrementing/decrementing the lock count and signalling the event.
687 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
689 tony 37 1.3.2 was never formally released and only made available as beta copies.
691 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
693     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
695     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
697     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
698     i.e. when it is a calculated field
700     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
701     This problem was due to a race condition between recalculating row heights and
702     determining which row was selected by the mouse click. The row height calculation
703     is now deferred by an extra trip round the message loop allowing the row to
704     be always calculated on the current grid layout rather than risking it being
705     calculated on the grid layout after the expanded row has been shrunk.
707     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
708     Windows.
710     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
711     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
712 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
713 tony 35
714     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
715 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
716 tony 35
717     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
718     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
719 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
720 tony 35
721     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
722     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
723     implies no truncation.
725     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
727     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
728     (avoids "Not in Edit Mode" error).
730     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
732     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
733     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
735     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
737     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
739     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
741     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
743 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
744 tony 31
745     1. OnCloseUp Event Handler added to TDBLookupProperties
747     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
748     problem with row size when exception is called.
750     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
752     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
753     in a TCustomComboBox and ignores return key if in a TCustomMemo
755     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
756     keyed in i.e. when autocomplete not performed
758 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
759     console mode applications with all LCL required functions (builtin dialogs and
760     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
761     not included in your project, IBX should compile and link with a console mode program.
762     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
763     console mode application or the IDE will automatically assume that your
764     application is GUI based. Instead, you should include the ibexpressconsolemode package.
765 tony 31
766     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
767     to use the built in dialogs and cursor management. IBDialogs is
768 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
769 tony 31 This should be the case for all projects created through the IDE. This is why
770     you do not want to add the ibexpress package to console mode applications. The
771     ibexpressconsolemode package has been created to allow console mode programs
772     to avoid adding LCL dependencies when using IBX, while still having the
773     unit search paths set up correctly.
775 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
776     each project's source file (*.lpr).
778 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
779     exists, you have to first open the package in the IDE and then close it. This
780     adds it to the most recently accessed packages list. To make it permanently
781     available, add the package name to lazarus' file.
783 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
784 tony 31
785     7. SQL Parser can now accept quoted strings that include new lines
787     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
788     of text on start of edit. This is particularly useful when tabbing to a
789     column and then inserting text.
791     9. New Examples provided for IB Services and ISQLMonitor.
793     10. Fix error when writing to blob streams that recorded only the last buffer
794     write in the blob stream. In most cases, this did not cause a problem as the
795     IB Blob Stream is written in a single write. However, with the TDBImage, write
796     of a graphic type prefix was lost which caused a problem when the image could
797     not be automatically recognised.
799     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
800 tony 33 already open" errors due to random numbers used for the cursor name being identical.
801 tony 31
802     12. IBTable: corrected error that could result in an "Index out of bounds" error
803     when opening the table and the Primary Key is the last or only column in the
804     table. Thanks to Rick Hoover for the fix.
806 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
807     of "UTF-8", and update list of available database character sets. Existing
808     users should check the current lc_ctype setting in their applications.
809 tony 29
810 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
812 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
813     empty Params property.
815     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
816     Link now set up in Loaded method - avoids occasional failure to apply
817     SQL markup on initial open.
819     3. "Employees" example performance improvements when scrolling.
821     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
822     TFrame. Force recaching of selected frame to avoid GTK race (results in a
823     random image cached).
825     5. DBControlGrid: Should now react to changes in panel height at run time.
827     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
828     even when further rows exist.
830     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
831     always be derived from panel height and setting this property can cause confusion.
832     Note for existing projects: to avoid a missing property error at run time,
833     each form using the DBControlGrid must be opened, updated and saved in the IDE
834     in order to remove the property value from the lfm.
837 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
838 tony 27
839     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
840     call Prepare before setting parameter values.
842     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
844     3. Code tidyup and more robust handling of dsql information result vector.
846     4. Support for centralised handling of transaction status changes. TIBTransaction
847     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
848     and "AfterExecQuery". The first three are called after the same event is called
849     for an IBCustomDataSet descendent using the Transaction. The fourth is called
850     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
851     enable monitoring of transaction status changes for a given transaction to be
852     handled in a single place. For example, when a change to the dataset occurs
853     an indicator can be set that shows the user that in order to save changes,
854     the transaction should be committed. Rather than doing this per dataset, this
855     can now be done per transaction.
857     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
858     the dataset is scrolled. However, any changes to the current row are, by default,
859     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
860     have a new property "DataSetCloseAction" that adds automatic posting of changes
861     on dataset close. If this property is set to dcDiscardChanges (default) then the
862     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
863     then IBX will attempt to post any unsaved changes before the dataset is closed
864     (and after the BeforeClose event handler is called). The exception is when the
865     dataset is being closed as a result of a transaction rollback. In this case,
866     no action is taken and any unsaved changes are discarded. This avoids both
867     unnecessary overhead and the risk that a validation error may occur in the Post
868     raising an exception and thereby preventing a rollback.
870     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
871     In earlier versions, the Display Width was set to the maximum byte width rather than the character
872     width. Display Widths are now corrected by dividing by the max byte width per character.
873     For UTF8 character sets, the byte width is four and hence the Display Width will be
874     the byte width divided by 4. The byte width of each character set is determined
875     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
876     system table. (see also
878     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
880     8. IBLookupComboEditBox: List should now always be restored to full list when the
881     control loses focus. Default Key press default interval reduced to 200ms.
883     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
884     when dataset rows are less than visible rows.
886     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
887     does not exist or DataSet is empty. More responsive on dataset open. New event
888     OnRestorePosition. Column sort disabled if no header row.
890     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
891     while dataset state is dsInsert. Avoids posting errors.
893     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
894     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
896     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
898     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
899     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
900     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
901     always "posts" the current record regardless or whether or not it may be more appropriate
902     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
903     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
904     as the first action of the "Post" method and allows the handler to convert the Post
905     into a Cancel if that is the appropriate action on moving to a different row. This is
906     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
907     raised here, but it may still be more appropriate to validate a post and signal
908     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
910     15. On Unix derived systems, the Firebird library name can now be given as a colon
911     separated list. Each library name on the list is tried in turn, in left to right
912     order with the first found being used as the firebird library. By default, on Linux,
913     the library name list is ''. This can be
914     overidden by the FBLIB environment variable or the OnGetLibraryName function.
916     Note: when using the, if you prefix the database name with "localhost:"
917     then it will still attempt to access the database via the Firebird Server and will
918     require a username and password. If only the pathname is given, then the username
919     and password should be omitted and the unix file permissions are used to grant
920     access.

924     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
925     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
926     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
927 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
928 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
930     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
931 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
932 tony 23 takes place during database access. This may be useful when there are performance issues with
933     the change of cursor. Setting the property to false suppresses the change of cursor.
935     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
936     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
937     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
938     making all changes permanent immediately rather than when the transaction is explicitly
939     committed.
941 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
942 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

950     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
951     This is typically used during an "OnBeforeOpen" event handler to manipulate the
952     "Where" and "Having" clauses to implement user specified filters of arbitrary
953     complexity.
955     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
956     three new data aware controls dependent on IBX and which make use of the SQL Parser.
957     These are:
959     - TIBLookupComboEditBox
960     - TIBDynamicGrid
961     - TIBTreeview
963     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
964     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
965     to revise the available list and restrict it to items that are prefixed by the
966 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
967 tony 21 newly typed entry to be added to the list dataset and included in the available
968     list items.
970     TIBDynamicGrid is a TDBGrid descendent that provides for:
971     - automatic resizing of selected columns to fill the available row length
972     - automatic positioning and sizing of a "totals" control, typically at the
973     column footer, on a per column basis.
974     - DataSet resorting on header row click, sorting the dataset by the selected column.
975     A second click on the same header cell reversed the sort order.
976     - Support for a "Panel Editor". That is on clicking the indicator column, the row
977     is automatically expanded and a panel superimposed on it. The panel can have any
978     number of child controls, typically data aware controls with the same datasource
979     as the grid allowing for editing of additional fields and more complex editors.
980     - Reselection of the same row following resorting.
981     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
982     Its properties are specified on a per column basis and allows for one or more
983     columns to have their values selected from a list provided by a dataset.
984     Autocomplete and autoinsert are also available. The existing picklist editor
985     is unaffected by the extension.
987     TIBTreeView is a data aware TCustomTreeView.
989     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
990     zero scale will no longer return an error. An Int64 will be returned instead.
992     4. TIBTransaction now has events for Before and After Transaction End and a new function
993     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
995     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
996     repeated multiple times.
998     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
999     check used to get in the way of using Stored Procedures, and "Update or Insert"
1000     statements.
1002     7. Insert, Modify and Delete property Editors now support Query Generation from
1003     Stored Procedures.
1005     8. Three new examples illustrate the use of the new IB Controls

1009 tony 19
1010     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1011     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1012     Gabor Boros for reporting this problem and for testing the improvements).
1014     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1015     See readme.field+param.names in the doc folder.
1017     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1018     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1020     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1022     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1023     actions.
1025     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1026     thanks to Yuriy Kopnin for pointing this out).
1028     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1030     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1031     for both fields and parameter setting.
1033     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1034     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1036     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1037     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1039     11. TIBTable now has a property editor for "MasterFields"
1041     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1042     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1044     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1045     of settings is unrecognised. Selecting this radio button has no effect on the settings.

1050     1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.

1054     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1055     it is null. This allows for alternative user defined setting of the generator
1057     Many thanks to Julio Jiménez for this fix
1059     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1060     and suggests that the user may have forgotten to install it.
1062 tony 13 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1064     1. Conditional compilation used to limit registration of TIntegerField to
1065     Lazarus versions less than 1.1
1067     2. When a database connection is created, character set is now by default set
1068     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1069     1250 to 1254.

1079     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1080     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1082     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1083     package is changed to do this (which it should do).
1085     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1087     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1089     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1091     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1093     4. Property editors should now correctly resize.
1095     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1096     (restored original functionality)
1098     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1099     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
