2    
3     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4     changes.
5    
6 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7     Bug could result in truncated multi-byte character set values.
8    
9 tony 60 3. Changes consequential on moving fbintf character set utility functions from
10     IFirebirdAPI to IAttachment.
11    
12 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
13 tony 49
14 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
15 tony 49 include remote system name.
16    
17     2. TIBExtract: No longer include comment header and COMMIT statement for empty
18     tables when data included in output.
19    
20     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
21     and timing information to be written to stdout. This may be used to locate
22     performance bottlenecks.
23    
24     4. SQLParser: only call "OnChanging" event handler when value is different.
25    
26     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
27    
28 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
29     that BindFields is called when the query is next activated. Avoids FieldName
30     not found error.
31    
32 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
33 tony 45
34 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
35 tony 45
36 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
37    
38     3. TIBExtract: data formatted as Charset set "octets" is now output using
39     hexadecimal notation.
40    
41     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
42     using a simple XML format.
43    
44     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
45     grants to these objects.
46    
47     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
48     dependency problems restoring complex databases.
49    
50     7. TIBXScript: This component has been restructured to allow for the processing of
51     embedded XML in INSERT statements and to support interactive sources in addition
52     to non-interactive data sources such as files.
53    
54     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
55    
56     9. TIBXScript: ISQL compatiable Set statements are now supported:
57     SET SQL DIALECT
58     SET TERM
59     SET AUTODDL
60     SET BAIL
61     SET ECHO
62     SET COUNT
63     SET STATS
64     SET NAMES <character set>
65    
66     10. IBVersion unit added to hold current IBX Version Number information.
67    
68     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
69     and domain definitions.
70    
71     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
72     fully supported.
73    
74     13. TIBExtract: when a database dump includes data, the generator values are now also set.
75    
76     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
77    
78     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
79    
80 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
81 tony 45 upgrading to IBX2.
82    
83     1. Size property of TIBStringField is now the width in characters of the field
84     and not the byte length. This applies only to multi-byte character sets such
85     as UTF8. The original approach aligned with TStringField. However, the TStringField
86     code is not recognised as a bug and hence this change to align the behaviour.
87     The TStringField change is expected in fpc 3.2.0.
88    
89     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
90     true (default) then Size property value saved in the lfm is ignored. Size is
91     always set from the dynamic information read from the database. It is unclear
92     why anyone would want to override this and set Size to false.
93    
94     3. ibxscript: should now handle correctly a Case..End statement within a procedure
95     block.
96    
97     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
98     exist when an attempt is made to connect to it (run time only) then an attempt
99     is made to create the database.
100    
101     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
102     has been successfully created as a result of a call to CreateDatabase or when
103     creating a database after it was found not to exist.
104    
105     6. DBControlGrid: a race condition could result in the wrong row image being
106     written to the cache. This has been avoided by a trip round the message
107     loop before rendering the row image.
108    
109     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
110     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
111     known to risk corrupt rendering of row images when the control is first
112     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
113     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
114    
115     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
116     a TDateEdit control located on an editor panel.
117    
118     9. TIBExtract: brought up-to-date plus many bug fixes.
119    
120     10. DBControlGrid: Removed memory leak when updating rows.
121    
122     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
123    
124 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
125    
126     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
127     when target codepage is CP_NONE. This is a workaround for
128     http://bugs.freepascal.org/view.php?id=30622.
129    
130     2. DBLog option removed from TIBStatisticalService - not supported by server
131     since Firebird 1.5.
132    
133     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
134     similar.
135    
136     4. IBCodePage: updated mapping between codepages and character id.
137    
138     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
139     Firebird. Character sets with a char width of two are not UTF16.
140    
141     6. Strings received from the database are now always transliterated into UTF8
142     regardless of the database character set or connection character set. This
143     is for compatibility with the LCL.
144    
145 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
146 tony 41
147     1. IBBlob: Defer reading of blob until read method called. This avoids having to
148     read in an entire blob just to get the size of the blob. General performance
149     improvement when opening datasets containing blobs.
150    
151     2. Clearing a Blob now sets the corresponding field's modified flag.
152    
153     3. IBLookupCombo: When not performing auto-complete, original query sort order
154     is now used.
155    
156     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
157     determined.
158    
159     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
160    
161     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
162     lazarus 1.6.0
163    
164     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
165     compilation error.
166    
167 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
168    
169     1. No character set specified for connection: when a text blob is retrieved, the
170     character set is determined by looking up the native character set using then
171     Firebird API. Otherwise a text mode blob is assumed to have the same character
172     set as the connection.
173    
174     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
175     for Login Dialog returing a change to the database path.
176    
177     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
178     to be changed from that given in the TIBDatabase/TIBServer component and for the
179     entered value to be saved on a project specific basis (design time only).
180    
181     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
182     column fieldname. If they are the same then it is acts as a look up for the KeyValue
183     Otherwise, it sets the column text to the selected ListField Value.
184    
185     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
186     column width.
187    
188     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
189     and a case insensitive search is requested.
190    
191     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
192     or column ListSource.
193    
194     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
195     unprepare) when closing and the text has not changed.
196    
197     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
198     Less likely to cause a cursor re-use error on Windows.
199    
200     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
201     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
202    
203     11. TIBTreeView: Guard against nil destination on record changed
204    
205     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
206     string type with the code page set to reflect the returned field encoding after
207     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
208     earlier versions.
209    
210     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
211     will now result in transliteration to the code page specified for the Firebird driver
212     if the assigned string has a different code page. FPC 3.0.0 onwards only.
213    
214     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
215     is ignored and the lc_ctype value, when the database is opened, is set to align with
216     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
217     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
218     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
219     the GETACP is used to determine the Windows code page.
220    
221     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
222     name used as the lc_ctype when the database was opened. Only valid while the
223     Database is connected.
224    
225     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
226     id that corresponds to the DefaultCharSetName.
227    
228 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
229    
230     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
231     path is given and database attach fails due to access permission issues on the
232     temp directory or security database, then the attach is retried with "localhost:"
233     prefixing the databasename. This should avoid problems when the database has to
234     be accessed by a local (e.g. classic) server and libfbembed is used.
235    
236     2. Windows: revised search order for Firebird DLL:
237     i. The Firebird Embedded Server in the application Directory.
238     ii. If the FIREBIRD environment variable is set then the directory this
239     points to is searched for the FB Client DLL and then then underlying
240     "bin" directory.
241     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
242     is used to locate the Firebird installation directory and the underlying
243     "bin" directory is searched for the FB Client DLL.
244     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
245     are searched for the FB Client DLL.
246     v. The PATH Environment variable is used to search for the FB Client DLL.
247     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
248    
249     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
250     See doc/readme.scriptengine and example applications.
251    
252     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
253     simplify the use of the embedded firebird server on both Linux and Windows platforms.
254     See dpc/readme.localdatabase and example applications.
255    
256     5. IBDynamicGrid: Reordering on column header click should now also work for
257     dynamic columns.
258    
259     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
260     between incrementing/decrementing the lock count and signalling the event.
261    
262 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
263    
264 tony 37 1.3.2 was never formally released and only made available as beta copies.
265    
266 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
267    
268     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
269    
270     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
271    
272     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
273     i.e. when it is a calculated field
274    
275     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
276     This problem was due to a race condition between recalculating row heights and
277     determining which row was selected by the mouse click. The row height calculation
278     is now deferred by an extra trip round the message loop allowing the row to
279     be always calculated on the current grid layout rather than risking it being
280     calculated on the grid layout after the expanded row has been shrunk.
281    
282     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
283     Windows.
284    
285     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
286     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
287 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
288 tony 35
289     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
290 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
291 tony 35
292     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
293     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
294 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
295 tony 35
296     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
297     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
298     implies no truncation.
299    
300     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
301    
302     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
303     (avoids "Not in Edit Mode" error).
304    
305     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
306    
307     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
308     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
309    
310     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
311    
312     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
313    
314     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
315    
316     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
317    
318 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
319 tony 31
320     1. OnCloseUp Event Handler added to TDBLookupProperties
321    
322     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
323     problem with row size when exception is called.
324    
325     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
326    
327     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
328     in a TCustomComboBox and ignores return key if in a TCustomMemo
329    
330     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
331     keyed in i.e. when autocomplete not performed
332    
333 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
334     console mode applications with all LCL required functions (builtin dialogs and
335     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
336     not included in your project, IBX should compile and link with a console mode program.
337     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
338     console mode application or the IDE will automatically assume that your
339     application is GUI based. Instead, you should include the ibexpressconsolemode package.
340 tony 31
341     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
342     to use the built in dialogs and cursor management. IBDialogs is
343 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
344 tony 31 This should be the case for all projects created through the IDE. This is why
345     you do not want to add the ibexpress package to console mode applications. The
346     ibexpressconsolemode package has been created to allow console mode programs
347     to avoid adding LCL dependencies when using IBX, while still having the
348     unit search paths set up correctly.
349    
350 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
351     each project's source file (*.lpr).
352    
353 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
354     exists, you have to first open the package in the IDE and then close it. This
355     adds it to the most recently accessed packages list. To make it permanently
356     available, add the package name to lazarus' staticpackages.inc file.
357    
358 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
359 tony 31
360     7. SQL Parser can now accept quoted strings that include new lines
361    
362     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
363     of text on start of edit. This is particularly useful when tabbing to a
364     column and then inserting text.
365    
366     9. New Examples provided for IB Services and ISQLMonitor.
367    
368     10. Fix error when writing to blob streams that recorded only the last buffer
369     write in the blob stream. In most cases, this did not cause a problem as the
370     IB Blob Stream is written in a single write. However, with the TDBImage, write
371     of a graphic type prefix was lost which caused a problem when the image could
372     not be automatically recognised.
373    
374     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
375 tony 33 already open" errors due to random numbers used for the cursor name being identical.
376 tony 31
377     12. IBTable: corrected error that could result in an "Index out of bounds" error
378     when opening the table and the Primary Key is the last or only column in the
379     table. Thanks to Rick Hoover for the fix.
380    
381 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
382     of "UTF-8", and update list of available database character sets. Existing
383     users should check the current lc_ctype setting in their applications.
384 tony 29
385 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
386    
387 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
388     empty Params property.
389    
390     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
391     Link now set up in Loaded method - avoids occasional failure to apply
392     SQL markup on initial open.
393    
394     3. "Employees" example performance improvements when scrolling.
395    
396     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
397     TFrame. Force recaching of selected frame to avoid GTK race (results in a
398     random image cached).
399    
400     5. DBControlGrid: Should now react to changes in panel height at run time.
401    
402     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
403     even when further rows exist.
404    
405     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
406     always be derived from panel height and setting this property can cause confusion.
407     Note for existing projects: to avoid a missing property error at run time,
408     each form using the DBControlGrid must be opened, updated and saved in the IDE
409     in order to remove the property value from the lfm.
410    
411    
412 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
413 tony 27
414     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
415     call Prepare before setting parameter values.
416    
417     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
418    
419     3. Code tidyup and more robust handling of dsql information result vector.
420    
421     4. Support for centralised handling of transaction status changes. TIBTransaction
422     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
423     and "AfterExecQuery". The first three are called after the same event is called
424     for an IBCustomDataSet descendent using the Transaction. The fourth is called
425     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
426     enable monitoring of transaction status changes for a given transaction to be
427     handled in a single place. For example, when a change to the dataset occurs
428     an indicator can be set that shows the user that in order to save changes,
429     the transaction should be committed. Rather than doing this per dataset, this
430     can now be done per transaction.
431    
432     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
433     the dataset is scrolled. However, any changes to the current row are, by default,
434     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
435     have a new property "DataSetCloseAction" that adds automatic posting of changes
436     on dataset close. If this property is set to dcDiscardChanges (default) then the
437     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
438     then IBX will attempt to post any unsaved changes before the dataset is closed
439     (and after the BeforeClose event handler is called). The exception is when the
440     dataset is being closed as a result of a transaction rollback. In this case,
441     no action is taken and any unsaved changes are discarded. This avoids both
442     unnecessary overhead and the risk that a validation error may occur in the Post
443     raising an exception and thereby preventing a rollback.
444    
445     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
446     In earlier versions, the Display Width was set to the maximum byte width rather than the character
447     width. Display Widths are now corrected by dividing by the max byte width per character.
448     For UTF8 character sets, the byte width is four and hence the Display Width will be
449     the byte width divided by 4. The byte width of each character set is determined
450     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
451     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
452    
453     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
454    
455     8. IBLookupComboEditBox: List should now always be restored to full list when the
456     control loses focus. Default Key press default interval reduced to 200ms.
457    
458     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
459     when dataset rows are less than visible rows.
460    
461     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
462     does not exist or DataSet is empty. More responsive on dataset open. New event
463     OnRestorePosition. Column sort disabled if no header row.
464    
465     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
466     while dataset state is dsInsert. Avoids posting errors.
467    
468     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
469     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
470    
471     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
472    
473     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
474     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
475     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
476     always "posts" the current record regardless or whether or not it may be more appropriate
477     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
478     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
479     as the first action of the "Post" method and allows the handler to convert the Post
480     into a Cancel if that is the appropriate action on moving to a different row. This is
481     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
482     raised here, but it may still be more appropriate to validate a post and signal
483     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
484    
485     15. On Unix derived systems, the Firebird library name can now be given as a colon
486     separated list. Each library name on the list is tried in turn, in left to right
487     order with the first found being used as the firebird library. By default, on Linux,
488     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
489     overidden by the FBLIB environment variable or the OnGetLibraryName function.
490    
491     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
492     then it will still attempt to access the database via the Firebird Server and will
493     require a username and password. If only the pathname is given, then the username
494     and password should be omitted and the unix file permissions are used to grant
495     access.

499     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
500     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
501     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
502 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
503 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
504    
505     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
506 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
507 tony 23 takes place during database access. This may be useful when there are performance issues with
508     the change of cursor. Setting the property to false suppresses the change of cursor.
509    
510     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
511     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
512     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
513     making all changes permanent immediately rather than when the transaction is explicitly
514     committed.
515    
516 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
517 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

524 tony 21
525     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
526     This is typically used during an "OnBeforeOpen" event handler to manipulate the
527     "Where" and "Having" clauses to implement user specified filters of arbitrary
528     complexity.
529    
530     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
531     three new data aware controls dependent on IBX and which make use of the SQL Parser.
532     These are:
533    
534     - TIBLookupComboEditBox
535     - TIBDynamicGrid
536     - TIBTreeview
537    
538     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
539     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
540     to revise the available list and restrict it to items that are prefixed by the
541 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
542 tony 21 newly typed entry to be added to the list dataset and included in the available
543     list items.
544    
545     TIBDynamicGrid is a TDBGrid descendent that provides for:
546     - automatic resizing of selected columns to fill the available row length
547     - automatic positioning and sizing of a "totals" control, typically at the
548     column footer, on a per column basis.
549     - DataSet resorting on header row click, sorting the dataset by the selected column.
550     A second click on the same header cell reversed the sort order.
551     - Support for a "Panel Editor". That is on clicking the indicator column, the row
552     is automatically expanded and a panel superimposed on it. The panel can have any
553     number of child controls, typically data aware controls with the same datasource
554     as the grid allowing for editing of additional fields and more complex editors.
555     - Reselection of the same row following resorting.
556     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
557     Its properties are specified on a per column basis and allows for one or more
558     columns to have their values selected from a list provided by a dataset.
559     Autocomplete and autoinsert are also available. The existing picklist editor
560     is unaffected by the extension.
561    
562     TIBTreeView is a data aware TCustomTreeView.
563    
564     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
565     zero scale will no longer return an error. An Int64 will be returned instead.
566    
567     4. TIBTransaction now has events for Before and After Transaction End and a new function
568     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
569    
570     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
571     repeated multiple times.
572    
573     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
574     check used to get in the way of using Stored Procedures, and "Update or Insert"
575     statements.
576    
577     7. Insert, Modify and Delete property Editors now support Query Generation from
578     Stored Procedures.
579    
580     8. Three new examples illustrate the use of the new IB Controls
581

584 tony 19
585     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
586     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
587     Gabor Boros for reporting this problem and for testing the improvements).
588    
589     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
590     See readme.field+param.names in the doc folder.
591    
592     3. IBX SQL Editors will now automatically add double quotes around column names when the database
593     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
594    
595     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
596    
597     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
598     actions.
599    
600     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
601     thanks to Yuriy Kopnin for pointing this out).
602    
603     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
604    
605     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
606     for both fields and parameter setting.
607    
608     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
609     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
610    
611     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
612     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
613    
614     11. TIBTable now has a property editor for "MasterFields"
615    
616     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
617     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
618    
619     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
620     of settings is unrecognised. Selecting this radio button has no effect on the settings.

629     1. In a TIBCustomDataset descendent, a generator now only sets the value when
630     it is null. This allows for alternative user defined setting of the generator
631    
632     Many thanks to Julio Jiménez for this fix
633    
634     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
635     and suggests that the user may have forgotten to install it.

639     1. Conditional compilation used to limit registration of TIntegerField to
640     Lazarus versions less than 1.1
641    
642     2. When a database connection is created, character set is now by default set
643     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
644     1250 to 1254.

654     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
655     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
656    
657     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
658     package is changed to do this (which it should do).
659    
660     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
661    
662     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
663    
664     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
665    
666     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
667    
668     4. Property editors should now correctly resize.
669    
670     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
671     (restored original functionality)
672    
673     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
674     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
