1 + IBX Change Log  version   (2.3-0) Wed, 14 Mar 2018 12:29:06 +0000
2 +
3 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4 + all previous copies of the IBX source code tree before installing this release.
5 +
6 + The IBX packages used by most users have not changed, with one exception. The
7 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8 + to use the IBServices unit in your applications, please add the iblegacyServices
9 + to the list of dependencies. To do this, open the Project Inspector and select
10 + Add->New Requirement and select "ibLegacyServices" from the list of available
11 + packages.
12 +
13 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14 +   the IBServices unit providing what is intended to be a clearer and easier to
15 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
16 +   more information and the guide to "Firebird Service Management Using IBX".
17 +   As indicated above, the legacy services components are still available and
18 +   provided in a separate package. There is no need to update working applications
19 +   using the older versions except for an additional package dependency.
20 +
21 + 2. The IBX packages and source code tree have been re-organised in an attempt to
22 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
23 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
24 +   new set of IBX packages.
25 +
26 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27 +   updated to use the new Services API components.
28 +
29 + 4. The iblocal package has been updated to use the new Services API components.
30 +
31 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32 +   TIBXSecurityService. It had been wrongly classified in the previous version
33 +   as a per database configuration item. It is global to a server and hence
34 +   correctly positioned as part of the Security Package. In the DBAdmin example,
35 +   the setting has moved to the mappings page.
36 +
37 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38 +   are ignored.
39 +
40 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41 +   closed before the database is dropped. Before and After Disconnect event handlers
42 +   are also fired.
43 +
44 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45 +   is started and not just the first time.
46 +
47 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48 +   depenendency with comp type.
49 +
50 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51 +
52 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53 +    then this is recognised and not ignored.
54 +
55 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
56 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
58 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
59 +
60 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
61 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
62 +    counters for the select query. Note: stats accumulate after each fetch from
63 +    the database. To get total query cost after open, call the "Last" method
64 +    and then GetPerfStatistics.
65 +
66 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67 +
68 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69 +    in parenthesises.
70 +
71 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72 +    SQL identifiers are always delimited by double quotes. If false, then they are
73 +    only delimited if the identifier is a reserved word, contains lower case or special
74 +    characters. Set this property to true to retain previous behaviour.
75 +
76 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
78 +
79 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
80 +       property MasterDetailDelay: integer {defaults to zero}
81 +
82 +    When non-zero and the dataset is a detail table referencing a master table
83 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84 +    then a synchronisation delay is added (in milliseconds) between the master
85 +    row changing and the detail dataset being re-opened. If the master dataset
86 +    is scrolled before the delay expires then the delay is reset. This can be used
87 +    to avoid performance overheads when scrolling through a large master dataset.
88 +
89 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
90 +    chreads unit must be included in your project. TTimer is not used in order
91 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92 +
93 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94 +    with Extract Option eoDatabase.
95 +
96 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97 +    When a deLaoutChanged event is reported on the ListSource dataset, the
98 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99 +    relationship with the control's datasource (master).
100 +
101 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
102 +
103 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
104 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
105 + RELEASE.
106 +
107 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
108 +
109 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
110 +
111 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
112 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
113 +   information). However, this is also a very useful mechanism for returning updated computed by
114 +   column values. Values returned as a result of executing an Insert or Update statement
115 +   replace existing values in the current row for each corresponding column.
116 +
117 +   Previously, if a dataset's select query included read only (computed by) fields then
118 +   an automatic row refresh was performed after an insert or update query had been processed,
119 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
120 +   that an automatic refresh is no longer performed if an insert or update query contains
121 +   a returning clause that updates one or more fields on the current row. A full row
122 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
123 +   field values and the select query contains read only fields. Use of Insert/update
124 +   returning should be significantly more efficient than executing a refresh query.
125 +
126 +   This behaviour change is intended to be backwards compatible and there should be no need to change
127 +   existing programs, other than to improve performance by using the new capability.
128 +
129 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
130 +   they are called when the dataset row is being deleted, there is no value in
131 +   updating the current record from the query result. Instead, a new event handler
132 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
133 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
134 +   by the query. The event handler can then interrogate the query results and
135 +   perform whatever action is necessary. For example to confirm, to the user,
136 +   the deletion of a row with the returned values.
137 +
138 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
139 +   any Computed By or Identity Columns. The IBTables example has been updated to
140 +   illustrate the computation of the employee Full Name on update.
141 +
142 + 5. TIBTable: The GeneratorField property is now published.
143 +
144 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
145 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
146 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
147 +   each Identity column after the insert is executed.
148 +
149 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
150 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
151 +   Insert..Returning clause.
152 +
153 + 8. TIBGenerator: small performance improvement by not preparing query each time
154 +   a new value is generated.
155 +
156 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
157 +
158 + 10. Property editors will now sync table name to a System Table when "Include System
159 +    Tables" is selected and the query is for a System Table.
160 +
161 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
162 +    values are no longer converted to milliseconds from TDateTime and then back again
163 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
164 +
165 + 12. Property Editors handling of Stored Procedures.
166 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
167 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
168 +      query).
169 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
170 +
171 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
172 +    can be used to select a package. If non-empty, the stored procedure name is
173 +    expected to be a stored procedure defined in the specified package and the
174 +    generated SQL will be as required for a stored procedure located in a package.
175 +
176 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
177 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
178 +    which a stored procedure can be selected. With no package name selected, non-package
179 +    stored procedures are listed.
180 +
181 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
182 +    for password on reconnect.
183 +
184 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
185 +    and character set name.
186 +
187 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
188 +    DB info lookups"
189 +
190 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
191 +
192 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
193 +
194 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
195 +    parameters. This stops an exception being raised when the field cannot be
196 +    located in the record buffer.
197 +
198 + 21. Property Editors now automatically include System Tables when opened and when the query table
199 +    is a System Table.
200 +
201 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
202 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
203 +
204 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
205 +    add the SPB item isc_spb_expected_db. This names a database using
206 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
207 +    database. examples/services re-written to illustrate use of "expected_db".
208 +
209 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
210 +    This avoids truncated backups when the server returns a timeout (busy) response.
211 +
212 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
213 +
214 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
215 +    databasenames. These are respectively expanded to the local system's temp directory
216 +    (including trailing delimiter) or to a prescribed data directory (including
217 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
218 +    in the user's home directory. The hidden directory name is either the string returned
219 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
220 +    Under Windows, the directory is the same as the Data Directory as decribed
221 +    above but instead prefixed by the User's application data path. These may be
222 +    used to improve application portability for Personal Databases.
223 +
224 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
225 +    this has not worked for a long time and is not useful either. FieldDefs should be
226 +    managed using the Fields Editor as with any other dataset. To access the fields
227 +    editor for a TIBTable component, double click on the component. The fields editor
228 +    is then displayed.
229 +
230 + 28. TIBDatabaseInfo: new properties/function
231 +     * DateDBCreated (returns date/time database created)
232 +     * TransactionCount (returns no. of active transactions)
233 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
234 +     * PagesFree (Firebird 3 or later)
235 +     * PagesUsed (Firebird 3 or later)
236 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
237 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
238 +
239 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
240 +
241 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
242 +
243 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
244 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
245 +
246 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
247 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
248 +    firing during backup and restore.
249 +
250 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
251 +    for verbose output using the new property "StatisticsRequested".
252 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
253 +
254 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
255 +
256 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
257 +    palette. This uses the online validation feature added in Firebird 2.5. The
258 +    services's properties enable inclusion/exclusion of tables and indexes using
259 +    regular expressions. See.
260 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
261 +
262 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
263 +    option on a database.
264 +
265 + 37. TIBCustomService: Assign method implemented to allow copying of service login
266 +    context between service API components. "Detach" method now only detaches
267 +    service when last reference to the service interface detaches. Tidy up of
268 +    code for SetActive and Attach methods including password hiding.
269 +
270 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
271 +    and used to determine the auth method and protocol used for the connection.
272 +
273 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
274 +    a Create Database Statement generated by IBX.
275 +
276 + 40. All IBServices now have an additional published property "PortNo". This may
277 +    be set to a non-standard port number when necessary. If zero then the default
278 +    port number is used.
279 +
280 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
281 +    and not just the mouse.
282 +
283 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
284 +
285 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
286 +    image index and selected image index for each node to be set from a database field.
287 +
288 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
289 +    then database schema includes grants to all users. If not present then the
290 +    only user grants included are those to User PUBLIC.
291 +
292 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
293 +    and child nodes in dataset.
294 +
295 +
296 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
297 +
298 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
299 +   changes.
300 +
301 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
302 +   Bug could result in truncated multi-byte character set values.
303 +
304 + 3. Changes consequential on moving fbintf character set utility functions from
305 +   IFirebirdAPI to IAttachment.
306 +
307 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
308 +
309 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
310 +   results in autocomplete ignoring prefix text.
311 +
312 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
313 +   entering a new name into the text box.
314 +
315 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
316 +   Firebird rather than recomputing it.
317 +
318 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
319 +   screen centre. Previously some were "poDesigned" which may be inappropriate
320 +   for multi monitor desktops.
321 +
322 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
323 +
324 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
325 +    a transaction and always reset the object.
326 +
327 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
328 +
329 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
330 +
331 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
332 +    to a gbak format archive.
333 +
334 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
335 +
336 + 16. IBLocaldb: Drop database if error creating an empty database.
337 +
338 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
339 +    unless selected node not in current dataset.
340 +
341 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
342 +    to TIBCustomService, and IBlocalDB code tidy up.
343 +
344 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
345 +    behaviour due to uninitialised variable.
346 +
347 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
348 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
349 +
350 + 21. IBSQL: When Database changed ensure that all resources are freed.
351 +
352 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
353 +
354 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
355 +    * Line Wrap on SQL Token boundaries (on user command)
356 +    * auto-complete table names in drop down list of table names
357 +    * Double click on tablename or field name adds to SQL text
358 +
359 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
360 +
361 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
362 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
363 +    workaround for a problem in fpc 3.0.4 win64).
364 +
365 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
366 +
367 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
368 +
369 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
370 +
371 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
372 +   include remote system name.
373 +
374 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
375 +   tables when data included in output.
376 +
377 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
378 +   and timing information to be written to stdout. This may be used to locate
379 +   performance bottlenecks.
380 +
381 + 4. SQLParser: only call "OnChanging" event handler when value is different.
382 +
383 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
384 +
385 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
386 +   that BindFields is called when the query is next activated. Avoids FieldName
387 +   not found error.
388 +
389 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
390 +   purpose and allows the programmer to define any action they want for Update, Insert
391 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
392 +   filtering of updates, or use of statements such as Grant or Revoke instead of
393 +   normal DML. See User Manual for more information.
394 +
395 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
396 +
397 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
398 +
399 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
400 +
401 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
402 +   hexadecimal notation.
403 +
404 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
405 +   using a simple XML format.
406 +
407 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
408 +   grants to these objects.
409 +
410 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
411 +   dependency problems restoring complex databases.
412 +
413 + 7. TIBXScript: This component has been restructured to allow for the processing of
414 +   embedded XML in INSERT statements and to support interactive sources in addition
415 +   to non-interactive data sources such as files.
416 +
417 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
418 +
419 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
420 +   SET SQL DIALECT
421 +   SET TERM
422 +   SET AUTODDL
423 +   SET BAIL
424 +   SET ECHO
425 +   SET COUNT
426 +   SET STATS
427 +   SET NAMES <character set>
428 +
429 + 10. IBVersion unit added to hold current IBX Version Number information.
430 +
431 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
432 +    and domain definitions.
433 +
434 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
435 +    fully supported.
436 +
437 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
438 +
439 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
440 +
441 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
442 +
443 + See also doc/IBX4LazarusGuide.pdf for important information on
444 + upgrading to IBX2.
445 +
446 + 1. Size property of TIBStringField is now the width in characters of the field
447 +   and not the byte length. This applies only to multi-byte character sets such
448 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
449 +   code is not recognised as a bug and hence this change to align the behaviour.
450 +   The TStringField change is expected in fpc 3.2.0.
451 +
452 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
453 +   true (default) then Size property value saved in the lfm is ignored. Size is
454 +   always set from the dynamic information read from the database. It is unclear
455 +   why anyone would want to override this and set Size to false.
456 +
457 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
458 +   block.
459 +
460 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
461 +   exist when an attempt is made to connect to it (run time only) then an attempt
462 +   is made to create the database.
463 +
464 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
465 +   has been successfully created as a result of a call to CreateDatabase or when
466 +   creating a database after it was found not to exist.
467 +
468 + 6.  DBControlGrid: a race condition could result in the wrong row image being
469 +    written to the cache. This has been avoided by a trip round the message
470 +    loop before rendering the row image.
471 +
472 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
473 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
474 +    known to risk corrupt rendering of row images when the control is first
475 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
476 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
477 +
478 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
479 +    a TDateEdit control located on an editor panel.
480 +
481 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
482 +
483 + 10. DBControlGrid: Removed memory leak when updating rows.
484 +
485 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
486 +
487 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
488 +
489 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
490 +   when target codepage is CP_NONE. This is a workaround for
491 +   http://bugs.freepascal.org/view.php?id=30622.
492 +
493 + 2. DBLog option removed from TIBStatisticalService - not supported by server
494 +   since Firebird 1.5.
495 +
496 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
497 +   similar.
498 +
499 + 4. IBCodePage: updated mapping between codepages and character id.
500 +
501 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
502 +   Firebird. Character sets with a char width of two are not UTF16.
503 +
504 + 6. Strings received from the database are now always transliterated into UTF8
505 +   regardless of the database character set or connection character set. This
506 +   is for compatibility with the LCL.
507 +
508 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
509 +
510 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
511 +   read in an entire blob just to get the size of the blob. General performance
512 +   improvement when opening datasets containing blobs.
513 +
514 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
515 +
516 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
517 +   is now used.
518 +
519 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
520 +   determined.
521 +
522 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
523 +
524 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
525 +   lazarus 1.6.0
526 +
527 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
528 +   compilation error.
529 +
530 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
531 +
532 + 1. No character set specified for connection: when a text blob is retrieved, the
533 +  character set is determined by looking up the native character set using then
534 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
535 +  set as the connection.
536 +
537 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
538 +   for Login Dialog returing a change to the database path.
539 +
540 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
541 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
542 +   entered value to be saved on a project specific basis (design time only).
543 +
544 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
545 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
546 +   Otherwise, it sets the column text to the selected ListField Value.
547 +
548 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
549 +   column width.
550 +
551 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
552 +   and a case insensitive search is requested.
553 +
554 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
555 +   or column ListSource.
556 +
557 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
558 +   unprepare) when closing and the text has not changed.
559 +
560 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
561 +   Less likely to cause a cursor re-use error on Windows.
562 +
563 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
564 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
565 +
566 + 11. TIBTreeView: Guard against nil destination on record changed
567 +
568 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
569 +    string type with the code page set to reflect the returned field encoding after
570 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
571 +    earlier versions.
572 +
573 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
574 +    will now result in transliteration to the code page specified for the Firebird driver
575 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
576 +
577 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
578 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
579 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
580 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
581 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
582 +    the GETACP is used to determine the Windows code page.
583 +
584 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
585 +    name used as the lc_ctype when the database was opened. Only valid while the
586 +    Database is connected.
587 +
588 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
589 +    id that corresponds to the DefaultCharSetName.
590 +
591 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
592 +
593 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
594 +   path is given and database attach fails due to access permission issues on the
595 +   temp directory or security database, then the attach is retried with "localhost:"
596 +   prefixing the databasename. This should avoid problems when the database has to
597 +   be accessed by a local (e.g. classic) server and libfbembed is used.
598 +
599 + 2. Windows: revised search order for Firebird DLL:
600 +     i.   The Firebird Embedded Server in the application Directory.
601 +     ii.  If the FIREBIRD environment variable is set then the directory this
602 +          points to is searched for the FB Client DLL and then then underlying
603 +          "bin" directory.
604 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
605 +          is used to locate the Firebird installation directory and the underlying
606 +          "bin" directory is searched for the FB Client DLL.
607 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
608 +          are searched for the FB Client DLL.
609 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
610 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
611 +
612 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
613 +   See doc/readme.scriptengine and example applications.
614 +
615 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
616 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
617 +   See dpc/readme.localdatabase and example applications.
618 +
619 + 5. IBDynamicGrid: Reordering on column header click should now also work for
620 +   dynamic columns.
621 +
622 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
623 +   between incrementing/decrementing the lock count and signalling the event.
624 +
625 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
626 +
627 + 1.3.2 was never formally released and only made available as beta copies.
628 +
629 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
630 +
631 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
632 +
633 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
634 +
635 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
636 +   i.e. when it is a calculated field
637 +
638 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
639 +   This problem was due to a race condition between recalculating row heights and
640 +   determining which row was selected by the mouse click. The row height calculation
641 +   is now deferred by an extra trip round the message loop allowing the row to
642 +   be always calculated on the current grid layout rather than risking it being
643 +   calculated on the grid layout after the expanded row has been shrunk.
644 +
645 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
646 +   Windows.
647 +
648 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
649 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
650 +   to be determined at runtime. See doc/readme.charactersets.html.
651 +
652 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
653 +   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
654 +
655 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
656 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
657 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
658 +
659 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
660 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
661 +   implies no truncation.
662 +
663 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
664 +
665 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
666 +   (avoids "Not in Edit Mode" error).
667 +
668 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
669 +
670 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
671 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
672 +
673 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
674 +
675 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
676 +
677 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
678 +
679 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
680 +
681 + IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
682 +
683 + 1.   OnCloseUp Event Handler added to TDBLookupProperties
684 +
685 + 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
686 +     problem with row size when exception is called.
687 +
688 + 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
689 +
690 + 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
691 +     in a TCustomComboBox and ignores return key if in a TCustomMemo
692 +
693 + 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
694 +     keyed in i.e. when autocomplete not performed
695 +
696 + 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
697 +     console mode applications with all LCL required functions (builtin dialogs and
698 +     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
699 +     not included in your project, IBX should compile and link with a console mode program.
700 +     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
701 +     console mode application or the IDE will automatically assume that your
702 +     application is GUI based. Instead, you should include the ibexpressconsolemode package.
703 +
704 +     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
705 +     to use the built in dialogs and cursor management. IBDialogs is
706 +     included by default if "ibexpress" is in your project source's "uses" clause.
707 +     This should be the case for all projects created through the IDE. This is why
708 +     you do not want to add the ibexpress package to console mode applications. The
709 +     ibexpressconsolemode package has been created to allow console mode programs
710 +     to avoid adding LCL dependencies when using IBX, while still having the
711 +     unit search paths set up correctly.
712 +
713 +     Existing users should check to ensure that the "ibexpress" unit is included in
714 +     each project's source file (*.lpr).
715 +
716 +     You may find that in order for the IDE to recognise that ibexpressconsolemode
717 +     exists, you have to first open the package in the IDE and then close it. This
718 +     adds it to the most recently accessed packages list. To make it permanently
719 +     available, add the package name to lazarus' staticpackages.inc file.
720 +
721 +         Thanks to Julio Jiménez for suggesting support of console mode.
722 +
723 + 7.   SQL Parser can now accept quoted strings that include new lines
724 +
725 + 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
726 +     of text on start of edit. This is particularly useful when tabbing to a
727 +     column and then inserting text.
728 +
729 + 9.   New Examples provided for IB Services and ISQLMonitor.
730 +
731 + 10. Fix error when writing to blob streams that recorded only the last buffer
732 +    write in the blob stream. In most cases, this did not cause a problem as the
733 +    IB Blob Stream is written in a single write. However, with the TDBImage, write
734 +    of a graphic type prefix was lost which caused a problem when the image could
735 +        not be automatically recognised.
736 +
737 + 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
738 +    already open" errors due to random numbers used for the cursor name being identical.
739 +
740 + 12. IBTable: corrected error that could result in an "Index out of bounds" error
741 +    when opening the table and the Primary Key is the last or only column in the
742 +    table. Thanks to Rick Hoover for the fix.
743 +
744 + 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
745 +    of "UTF-8", and update list of available database character sets. Existing
746 +    users should check the current lc_ctype setting in their applications.
747 +
748 + IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
749 +
750 + 1.  Firebird Services: avoid List Index error when opening a service with an
751 +    empty Params property.
752 +
753 + 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
754 +    Link now set up in Loaded method - avoids occasional failure to apply
755 +    SQL markup on initial open.
756 +
757 + 3.  "Employees" example performance improvements when scrolling.
758 +
759 + 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
760 +    TFrame. Force recaching of selected frame to avoid GTK race (results in a
761 +    random image cached).
762 +
763 + 5.  DBControlGrid: Should now react to changes in panel height at run time.
764 +
765 + 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
766 +    even when further rows exist.
767 +
768 + 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
769 +    always be derived from panel height and setting this property can cause confusion.
770 +    Note for existing projects: to avoid a missing property error at run time,
771 +    each form using the DBControlGrid must be opened, updated and saved in the IDE
772 +    in order to remove the property value from the lfm.
773 +
774 +
775 + IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
776 +
777 + 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
778 +    call Prepare before setting parameter values.
779 +
780 + 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
781 +
782 + 3.  Code tidyup and more robust handling of dsql information result vector.
783 +
784 + 4.  Support for centralised handling of transaction status changes. TIBTransaction
785 +    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
786 +    and "AfterExecQuery". The first three are called after the same event is called
787 +    for an IBCustomDataSet descendent using the Transaction. The fourth is called
788 +    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
789 +    enable monitoring of transaction status changes for a given transaction to be
790 +    handled in a single place. For example, when a change to the dataset occurs
791 +    an indicator can be set that shows the user that in order to save changes,
792 +    the transaction should be committed.  Rather than doing this per dataset, this
793 +    can now be done per transaction.
794 +
795 + 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
796 +    the dataset is scrolled. However, any changes to the current row are, by default,
797 +    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
798 +    have a new property "DataSetCloseAction" that adds automatic posting of changes
799 +    on dataset close. If this property is set to dcDiscardChanges (default) then the
800 +    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
801 +    then IBX will attempt to post any unsaved changes before the dataset is closed
802 +    (and after the BeforeClose event handler is called). The exception is when the
803 +    dataset is being closed as a result of a transaction rollback. In this case,
804 +    no action is taken and any unsaved  changes are discarded. This avoids both
805 +    unnecessary overhead and the risk that a validation error may occur in the Post
806 +    raising an exception and thereby preventing a rollback.
807 +
808 + 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
809 +    In earlier versions, the Display Width was set to the maximum byte width rather than the character
810 +    width. Display Widths are now corrected by dividing by the max byte width per character.
811 +    For UTF8 character sets, the byte width is four and hence the Display Width will be
812 +    the byte width divided by 4. The byte width of each character set is determined
813 +    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
814 +    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
815 +
816 + 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
817 +
818 + 8.  IBLookupComboEditBox: List should now always be restored to full list when the
819 +    control loses focus. Default Key press default interval reduced to 200ms.
820 +
821 + 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
822 +    when dataset rows are less than visible rows.
823 +
824 + 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
825 +    does not exist or DataSet is empty. More responsive on dataset open. New event
826 +    OnRestorePosition. Column sort disabled if no header row.
827 +
828 + 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
829 +    while dataset state is dsInsert. Avoids posting errors.
830 +
831 + 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
832 +    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
833 +
834 + 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
835 +
836 + 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
837 +    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
838 +    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
839 +    always "posts" the current record regardless or whether or not it may be more appropriate
840 +    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
841 +    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
842 +    as the first action of the "Post" method and allows the handler to convert the Post
843 +    into a Cancel if that is the appropriate action on moving to a different row. This is
844 +    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
845 +    raised here, but it may still be more appropriate to validate a post and signal
846 +    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
847 +
848 + 15. On Unix derived systems, the Firebird library name can now be given as a colon
849 +    separated list. Each library name on the list is tried in turn, in left to right
850 +    order with the first found being used as the firebird library. By default, on Linux,
851 +    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
852 +    overidden by the FBLIB environment variable or the OnGetLibraryName function.
853 +
854 +    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
855 +    then it will still attempt to access the database via the Firebird Server and will
856 +    require a username and password. If only the pathname is given, then the username
857 +    and password should be omitted and the unix file permissions are used to grant
858 +    access.

860 + IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
861 +
862 + 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
863 +    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
864 +    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
865 +    corresponds to a row of the linked DataSource. Any data aware control on the
866 +    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
867 +
868 + 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
869 +   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
870 +   takes place during database access. This may be useful when there are performance issues with
871 +   the change of cursor. Setting the property to false suppresses the change of cursor.
872 +
873 + 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
874 +   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
875 +   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
876 +   making all changes permanent immediately rather than when the transaction is explicitly
877 +   committed.
878 +
879 + 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
880 +   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

884 + Development version only.
885 +
886 + IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
887 +
888 + 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
889 +   This is typically used during an "OnBeforeOpen" event handler to manipulate the
890 +   "Where" and "Having" clauses to implement user specified filters of arbitrary
891 +   complexity.
892 +
893 + 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
894 +   three new data aware controls dependent on IBX and which make use of the SQL Parser.
895 +   These are:
896 +
897 +   - TIBLookupComboEditBox
898 +   - TIBDynamicGrid
899 +   - TIBTreeview
900 +
901 +   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
902 +   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
903 +   to revise the available list and restrict it to items that are prefixed by the
904 +   typed text (either case sensitive or case insensitive). Autoinsert allows a
905 +   newly typed entry to be added to the list dataset and included in the available
906 +   list items.
907 +
908 +   TIBDynamicGrid is a TDBGrid descendent that provides for:
909 +   - automatic resizing of selected columns to fill the available row length
910 +   - automatic positioning and sizing of a "totals" control, typically at the
911 +     column footer, on a per column basis.
912 +   - DataSet resorting on header row click, sorting the dataset by the selected column.
913 +     A second click on the same header cell reversed the sort order.
914 +   - Support for a "Panel Editor". That is on clicking the indicator column, the row
915 +     is automatically expanded and a panel superimposed on it. The panel can have any
916 +     number of child controls, typically data aware controls with the same datasource
917 +     as the grid allowing for editing of additional fields and more complex editors.
918 +   - Reselection of the same row following resorting.
919 +   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
920 +     Its properties are specified on a per column basis and allows for one or more
921 +     columns to have their values selected from a list provided by a dataset.
922 +     Autocomplete and autoinsert are also available. The existing picklist editor
923 +     is unaffected by the extension.
924 +
925 +   TIBTreeView is a data aware TCustomTreeView.
926 +
927 + 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
928 +   zero scale will no longer return an error. An Int64 will be returned instead.
929 +
930 + 4. TIBTransaction now has events for Before and After Transaction End and a new function
931 +   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
932 +
933 + 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
934 +   repeated multiple times.
935 +
936 + 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
937 +   check used to get in the way of using Stored Procedures, and "Update or Insert"
938 +   statements.
939 +
940 + 7. Insert, Modify and Delete property Editors now support Query Generation from
941 +   Stored Procedures.
942 +
943 + 8. Three new examples illustrate the use of the new IB Controls
944 +
945 +
946 + IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
947 +
948 + 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
949 +   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
950 +   Gabor Boros for reporting this problem and for testing the improvements).
951 +
952 + 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
953 +   See readme.field+param.names in the doc folder.
954 +
955 + 3. IBX SQL Editors will now automatically add double quotes around column names when the database
956 +   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
957 +
958 + 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
959 +
960 + 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
961 +   actions.
962 +
963 + 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
964 +   thanks to Yuriy Kopnin for pointing this out).
965 +
966 + 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
967 +
968 + 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
969 +   for both fields and parameter setting.
970 +
971 + 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
972 +   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
973 +
974 + 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
975 +    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
976 +
977 + 11. TIBTable now has a property editor for "MasterFields"
978 +
979 + 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
980 +    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
981 +
982 + 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
983 +    of settings is unrecognised. Selecting this radio button has no effect on the settings.
984 +

988 + 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
989 +
990 + IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
991 +
992 + 1. In a TIBCustomDataset descendent, a generator now only sets the value when
993 +   it is null. This allows for alternative user defined setting of the generator
994 +
995 +   Many thanks to Julio Jiménez for this fix
996 +
997 + 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
998 +   and suggests that the user may have forgotten to install it.
999 +
1000 + IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1001 +
1002 + 1. Conditional compilation used to limit registration of TIntegerField to
1003 +   Lazarus versions less than 1.1
1004 +
1005 + 2. When a database connection is created, character set is now by default set
1006 +   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1007 +   1250 to 1254.
1008 +
1009 +
