1 IBX Change Log version (2.0.3) tba, 24 Feb 2017 12:17:53 +0000
2
3 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 changes.
5
6 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7 Bug could result in truncated multi-byte character set values.
8
9 3. Changes consequential on moving fbintf character set utility functions from
10 IFirebirdAPI to IAttachment.
11
12 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
13
14 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
15 results in autocomplete ignoring prefix text.
16
17 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
18 entering a new name into the text box.
19
20 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
21 Firebird rather than recomputing it.
22
23 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
24
25 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
26 include remote system name.
27
28 2. TIBExtract: No longer include comment header and COMMIT statement for empty
29 tables when data included in output.
30
31 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
32 and timing information to be written to stdout. This may be used to locate
33 performance bottlenecks.
34
35 4. SQLParser: only call "OnChanging" event handler when value is different.
36
37 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
38
39 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
40 that BindFields is called when the query is next activated. Avoids FieldName
41 not found error.
42
43 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
44
45 1. TIBEvents: Fix uninitialised variable that could result in lost events.
46
47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
48
49 3. TIBExtract: data formatted as Charset set "octets" is now output using
50 hexadecimal notation.
51
52 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
53 using a simple XML format.
54
55 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
56 grants to these objects.
57
58 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
59 dependency problems restoring complex databases.
60
61 7. TIBXScript: This component has been restructured to allow for the processing of
62 embedded XML in INSERT statements and to support interactive sources in addition
63 to non-interactive data sources such as files.
64
65 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
66
67 9. TIBXScript: ISQL compatiable Set statements are now supported:
68 SET SQL DIALECT
69 SET TERM
70 SET AUTODDL
71 SET BAIL
72 SET ECHO
73 SET COUNT
74 SET STATS
75 SET NAMES <character set>
76
77 10. IBVersion unit added to hold current IBX Version Number information.
78
79 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
80 and domain definitions.
81
82 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
83 fully supported.
84
85 13. TIBExtract: when a database dump includes data, the generator values are now also set.
86
87 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
88
89 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
90
91 See also doc/IBX4LazarusGuide.pdf for important information on
92 upgrading to IBX2.
93
94 1. Size property of TIBStringField is now the width in characters of the field
95 and not the byte length. This applies only to multi-byte character sets such
96 as UTF8. The original approach aligned with TStringField. However, the TStringField
97 code is not recognised as a bug and hence this change to align the behaviour.
98 The TStringField change is expected in fpc 3.2.0.
99
100 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
101 true (default) then Size property value saved in the lfm is ignored. Size is
102 always set from the dynamic information read from the database. It is unclear
103 why anyone would want to override this and set Size to false.
104
105 3. ibxscript: should now handle correctly a Case..End statement within a procedure
106 block.
107
108 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
109 exist when an attempt is made to connect to it (run time only) then an attempt
110 is made to create the database.
111
112 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
113 has been successfully created as a result of a call to CreateDatabase or when
114 creating a database after it was found not to exist.
115
116 6. DBControlGrid: a race condition could result in the wrong row image being
117 written to the cache. This has been avoided by a trip round the message
118 loop before rendering the row image.
119
120 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
121 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
122 known to risk corrupt rendering of row images when the control is first
123 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
124 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
125
126 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
127 a TDateEdit control located on an editor panel.
128
129 9. TIBExtract: brought up-to-date plus many bug fixes.
130
131 10. DBControlGrid: Removed memory leak when updating rows.
132
133 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
134
135 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
136
137 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
138 when target codepage is CP_NONE. This is a workaround for
139 http://bugs.freepascal.org/view.php?id=30622.
140
141 2. DBLog option removed from TIBStatisticalService - not supported by server
142 since Firebird 1.5.
143
144 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
145 similar.
146
147 4. IBCodePage: updated mapping between codepages and character id.
148
149 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
150 Firebird. Character sets with a char width of two are not UTF16.
151
152 6. Strings received from the database are now always transliterated into UTF8
153 regardless of the database character set or connection character set. This
154 is for compatibility with the LCL.
155
156 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
157
158 1. IBBlob: Defer reading of blob until read method called. This avoids having to
159 read in an entire blob just to get the size of the blob. General performance
160 improvement when opening datasets containing blobs.
161
162 2. Clearing a Blob now sets the corresponding field's modified flag.
163
164 3. IBLookupCombo: When not performing auto-complete, original query sort order
165 is now used.
166
167 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
168 determined.
169
170 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
171
172 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
173 lazarus 1.6.0
174
175 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
176 compilation error.
177
178 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
179
180 1. No character set specified for connection: when a text blob is retrieved, the
181 character set is determined by looking up the native character set using then
182 Firebird API. Otherwise a text mode blob is assumed to have the same character
183 set as the connection.
184
185 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
186 for Login Dialog returing a change to the database path.
187
188 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
189 to be changed from that given in the TIBDatabase/TIBServer component and for the
190 entered value to be saved on a project specific basis (design time only).
191
192 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
193 column fieldname. If they are the same then it is acts as a look up for the KeyValue
194 Otherwise, it sets the column text to the selected ListField Value.
195
196 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
197 column width.
198
199 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
200 and a case insensitive search is requested.
201
202 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
203 or column ListSource.
204
205 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
206 unprepare) when closing and the text has not changed.
207
208 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
209 Less likely to cause a cursor re-use error on Windows.
210
211 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
212 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
213
214 11. TIBTreeView: Guard against nil destination on record changed
215
216 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
217 string type with the code page set to reflect the returned field encoding after
218 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
219 earlier versions.
220
221 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
222 will now result in transliteration to the code page specified for the Firebird driver
223 if the assigned string has a different code page. FPC 3.0.0 onwards only.
224
225 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
226 is ignored and the lc_ctype value, when the database is opened, is set to align with
227 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
228 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
229 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
230 the GETACP is used to determine the Windows code page.
231
232 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
233 name used as the lc_ctype when the database was opened. Only valid while the
234 Database is connected.
235
236 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
237 id that corresponds to the DefaultCharSetName.
238
239 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
240
241 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
242 path is given and database attach fails due to access permission issues on the
243 temp directory or security database, then the attach is retried with "localhost:"
244 prefixing the databasename. This should avoid problems when the database has to
245 be accessed by a local (e.g. classic) server and libfbembed is used.
246
247 2. Windows: revised search order for Firebird DLL:
248 i. The Firebird Embedded Server in the application Directory.
249 ii. If the FIREBIRD environment variable is set then the directory this
250 points to is searched for the FB Client DLL and then then underlying
251 "bin" directory.
252 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
253 is used to locate the Firebird installation directory and the underlying
254 "bin" directory is searched for the FB Client DLL.
255 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
256 are searched for the FB Client DLL.
257 v. The PATH Environment variable is used to search for the FB Client DLL.
258 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
259
260 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
261 See doc/readme.scriptengine and example applications.
262
263 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
264 simplify the use of the embedded firebird server on both Linux and Windows platforms.
265 See dpc/readme.localdatabase and example applications.
266
267 5. IBDynamicGrid: Reordering on column header click should now also work for
268 dynamic columns.
269
270 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
271 between incrementing/decrementing the lock count and signalling the event.
272
273 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
274
275 1.3.2 was never formally released and only made available as beta copies.
276
277 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
278
279 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
280
281 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
282
283 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
284 i.e. when it is a calculated field
285
286 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
287 This problem was due to a race condition between recalculating row heights and
288 determining which row was selected by the mouse click. The row height calculation
289 is now deferred by an extra trip round the message loop allowing the row to
290 be always calculated on the current grid layout rather than risking it being
291 calculated on the grid layout after the expanded row has been shrunk.
292
293 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
294 Windows.
295
296 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
297 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
298 to be determined at runtime. See doc/readme.charactersets.html.
299
300 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
301 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
302
303 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
304 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
305 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
306
307 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
308 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
309 implies no truncation.
310
311 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
312
313 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
314 (avoids "Not in Edit Mode" error).
315
316 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
317
318 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
319 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
320
321 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
322
323 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
324
325 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
326
327 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
328
329 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
330
331 1. OnCloseUp Event Handler added to TDBLookupProperties
332
333 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
334 problem with row size when exception is called.
335
336 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
337
338 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
339 in a TCustomComboBox and ignores return key if in a TCustomMemo
340
341 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
342 keyed in i.e. when autocomplete not performed
343
344 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
345 console mode applications with all LCL required functions (builtin dialogs and
346 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
347 not included in your project, IBX should compile and link with a console mode program.
348 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
349 console mode application or the IDE will automatically assume that your
350 application is GUI based. Instead, you should include the ibexpressconsolemode package.
351
352 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
353 to use the built in dialogs and cursor management. IBDialogs is
354 included by default if "ibexpress" is in your project source's "uses" clause.
355 This should be the case for all projects created through the IDE. This is why
356 you do not want to add the ibexpress package to console mode applications. The
357 ibexpressconsolemode package has been created to allow console mode programs
358 to avoid adding LCL dependencies when using IBX, while still having the
359 unit search paths set up correctly.
360
361 Existing users should check to ensure that the "ibexpress" unit is included in
362 each project's source file (*.lpr).
363
364 You may find that in order for the IDE to recognise that ibexpressconsolemode
365 exists, you have to first open the package in the IDE and then close it. This
366 adds it to the most recently accessed packages list. To make it permanently
367 available, add the package name to lazarus' staticpackages.inc file.
368
369 Thanks to Julio Jiménez for suggesting support of console mode.
370
371 7. SQL Parser can now accept quoted strings that include new lines
372
373 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
374 of text on start of edit. This is particularly useful when tabbing to a
375 column and then inserting text.
376
377 9. New Examples provided for IB Services and ISQLMonitor.
378
379 10. Fix error when writing to blob streams that recorded only the last buffer
380 write in the blob stream. In most cases, this did not cause a problem as the
381 IB Blob Stream is written in a single write. However, with the TDBImage, write
382 of a graphic type prefix was lost which caused a problem when the image could
383 not be automatically recognised.
384
385 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
386 already open" errors due to random numbers used for the cursor name being identical.
387
388 12. IBTable: corrected error that could result in an "Index out of bounds" error
389 when opening the table and the Primary Key is the last or only column in the
390 table. Thanks to Rick Hoover for the fix.
391
392 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
393 of "UTF-8", and update list of available database character sets. Existing
394 users should check the current lc_ctype setting in their applications.
395
396 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
397
398 1. Firebird Services: avoid List Index error when opening a service with an
399 empty Params property.
400
401 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
402 Link now set up in Loaded method - avoids occasional failure to apply
403 SQL markup on initial open.
404
405 3. "Employees" example performance improvements when scrolling.
406
407 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
408 TFrame. Force recaching of selected frame to avoid GTK race (results in a
409 random image cached).
410
411 5. DBControlGrid: Should now react to changes in panel height at run time.
412
413 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
414 even when further rows exist.
415
416 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
417 always be derived from panel height and setting this property can cause confusion.
418 Note for existing projects: to avoid a missing property error at run time,
419 each form using the DBControlGrid must be opened, updated and saved in the IDE
420 in order to remove the property value from the lfm.
421
422
423 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
424
425 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
426 call Prepare before setting parameter values.
427
428 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
429
430 3. Code tidyup and more robust handling of dsql information result vector.
431
432 4. Support for centralised handling of transaction status changes. TIBTransaction
433 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
434 and "AfterExecQuery". The first three are called after the same event is called
435 for an IBCustomDataSet descendent using the Transaction. The fourth is called
436 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
437 enable monitoring of transaction status changes for a given transaction to be
438 handled in a single place. For example, when a change to the dataset occurs
439 an indicator can be set that shows the user that in order to save changes,
440 the transaction should be committed. Rather than doing this per dataset, this
441 can now be done per transaction.
442
443 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
444 the dataset is scrolled. However, any changes to the current row are, by default,
445 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
446 have a new property "DataSetCloseAction" that adds automatic posting of changes
447 on dataset close. If this property is set to dcDiscardChanges (default) then the
448 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
449 then IBX will attempt to post any unsaved changes before the dataset is closed
450 (and after the BeforeClose event handler is called). The exception is when the
451 dataset is being closed as a result of a transaction rollback. In this case,
452 no action is taken and any unsaved changes are discarded. This avoids both
453 unnecessary overhead and the risk that a validation error may occur in the Post
454 raising an exception and thereby preventing a rollback.
455
456 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
457 In earlier versions, the Display Width was set to the maximum byte width rather than the character
458 width. Display Widths are now corrected by dividing by the max byte width per character.
459 For UTF8 character sets, the byte width is four and hence the Display Width will be
460 the byte width divided by 4. The byte width of each character set is determined
461 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
462 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
463
464 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
465
466 8. IBLookupComboEditBox: List should now always be restored to full list when the
467 control loses focus. Default Key press default interval reduced to 200ms.
468
469 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
470 when dataset rows are less than visible rows.
471
472 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
473 does not exist or DataSet is empty. More responsive on dataset open. New event
474 OnRestorePosition. Column sort disabled if no header row.
475
476 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
477 while dataset state is dsInsert. Avoids posting errors.
478
479 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
480 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
481
482 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
483
484 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
485 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
486 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
487 always "posts" the current record regardless or whether or not it may be more appropriate
488 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
489 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
490 as the first action of the "Post" method and allows the handler to convert the Post
491 into a Cancel if that is the appropriate action on moving to a different row. This is
492 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
493 raised here, but it may still be more appropriate to validate a post and signal
494 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
495
496 15. On Unix derived systems, the Firebird library name can now be given as a colon
497 separated list. Each library name on the list is tried in turn, in left to right
498 order with the first found being used as the firebird library. By default, on Linux,
499 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
500 overidden by the FBLIB environment variable or the OnGetLibraryName function.
501
502 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
503 then it will still attempt to access the database via the Firebird Server and will
504 require a username and password. If only the pathname is given, then the username
505 and password should be omitted and the unix file permissions are used to grant
506 access.

508 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
509
510 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
511 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
512 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
513 corresponds to a row of the linked DataSource. Any data aware control on the
514 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
515
516 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
517 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
518 takes place during database access. This may be useful when there are performance issues with
519 the change of cursor. Setting the property to false suppresses the change of cursor.
520
521 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
522 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
523 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
524 making all changes permanent immediately rather than when the transaction is explicitly
525 committed.
526
527 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
528 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

531
532 Development version only.
533
534 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
535
536 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
537 This is typically used during an "OnBeforeOpen" event handler to manipulate the
538 "Where" and "Having" clauses to implement user specified filters of arbitrary
539 complexity.
540
541 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
542 three new data aware controls dependent on IBX and which make use of the SQL Parser.
543 These are:
544
545 - TIBLookupComboEditBox
546 - TIBDynamicGrid
547 - TIBTreeview
548
549 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
550 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
551 to revise the available list and restrict it to items that are prefixed by the
552 typed text (either case sensitive or case insensitive). Autoinsert allows a
553 newly typed entry to be added to the list dataset and included in the available
554 list items.
555
556 TIBDynamicGrid is a TDBGrid descendent that provides for:
557 - automatic resizing of selected columns to fill the available row length
558 - automatic positioning and sizing of a "totals" control, typically at the
559 column footer, on a per column basis.
560 - DataSet resorting on header row click, sorting the dataset by the selected column.
561 A second click on the same header cell reversed the sort order.
562 - Support for a "Panel Editor". That is on clicking the indicator column, the row
563 is automatically expanded and a panel superimposed on it. The panel can have any
564 number of child controls, typically data aware controls with the same datasource
565 as the grid allowing for editing of additional fields and more complex editors.
566 - Reselection of the same row following resorting.
567 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
568 Its properties are specified on a per column basis and allows for one or more
569 columns to have their values selected from a list provided by a dataset.
570 Autocomplete and autoinsert are also available. The existing picklist editor
571 is unaffected by the extension.
572
573 TIBTreeView is a data aware TCustomTreeView.
574
575 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
576 zero scale will no longer return an error. An Int64 will be returned instead.
577
578 4. TIBTransaction now has events for Before and After Transaction End and a new function
579 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
580
581 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
582 repeated multiple times.
583
584 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
585 check used to get in the way of using Stored Procedures, and "Update or Insert"
586 statements.
587
588 7. Insert, Modify and Delete property Editors now support Query Generation from
589 Stored Procedures.
590
591 8. Three new examples illustrate the use of the new IB Controls
592
593
594 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
595
596 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
597 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
598 Gabor Boros for reporting this problem and for testing the improvements).
599
600 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
601 See readme.field+param.names in the doc folder.
602
603 3. IBX SQL Editors will now automatically add double quotes around column names when the database
604 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
605
606 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
607
608 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
609 actions.
610
611 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
612 thanks to Yuriy Kopnin for pointing this out).
613
614 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
615
616 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
617 for both fields and parameter setting.
618
619 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
620 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
621
622 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
623 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
624
625 11. TIBTable now has a property editor for "MasterFields"
626
627 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
628 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
629
630 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
631 of settings is unrecognised. Selecting this radio button has no effect on the settings.
632

634 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
635
636 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
637
638 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
639
640 1. In a TIBCustomDataset descendent, a generator now only sets the value when
641 it is null. This allows for alternative user defined setting of the generator
642
643 Many thanks to Julio Jiménez for this fix
644
645 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
646 and suggests that the user may have forgotten to install it.
647
648 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
649
650 1. Conditional compilation used to limit registration of TIntegerField to
651 Lazarus versions less than 1.1
652
653 2. When a database connection is created, character set is now by default set
654 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
655 1250 to 1254.
656
657
658 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
659
660 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
661
662
663 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
664
665 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
666 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
667
668 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
669 package is changed to do this (which it should do).
670
671 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
672
673 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
674
675 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
676
677 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
678
679 4. Property editors should now correctly resize.
680
681 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
682 (restored original functionality)
683
684 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
685 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
