   entering a new name into the text box

File Contents

# Content
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.

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

505 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
506
507 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
508 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
509 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
510 corresponds to a row of the linked DataSource. Any data aware control on the
511 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
512
513 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
514 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
515 takes place during database access. This may be useful when there are performance issues with
516 the change of cursor. Setting the property to false suppresses the change of cursor.
517
518 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
519 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
520 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
521 making all changes permanent immediately rather than when the transaction is explicitly
522 committed.
523
524 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
525 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

531 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
532
533 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
534 This is typically used during an "OnBeforeOpen" event handler to manipulate the
535 "Where" and "Having" clauses to implement user specified filters of arbitrary
536 complexity.
537
538 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
539 three new data aware controls dependent on IBX and which make use of the SQL Parser.
540 These are:
541
542 - TIBLookupComboEditBox
543 - TIBDynamicGrid
544 - TIBTreeview
545
546 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
547 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
548 to revise the available list and restrict it to items that are prefixed by the
549 typed text (either case sensitive or case insensitive). Autoinsert allows a
550 newly typed entry to be added to the list dataset and included in the available
551 list items.
552
553 TIBDynamicGrid is a TDBGrid descendent that provides for:
554 - automatic resizing of selected columns to fill the available row length
555 - automatic positioning and sizing of a "totals" control, typically at the
556 column footer, on a per column basis.
557 - DataSet resorting on header row click, sorting the dataset by the selected column.
558 A second click on the same header cell reversed the sort order.
559 - Support for a "Panel Editor". That is on clicking the indicator column, the row
560 is automatically expanded and a panel superimposed on it. The panel can have any
561 number of child controls, typically data aware controls with the same datasource
562 as the grid allowing for editing of additional fields and more complex editors.
563 - Reselection of the same row following resorting.
564 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
565 Its properties are specified on a per column basis and allows for one or more
566 columns to have their values selected from a list provided by a dataset.
567 Autocomplete and autoinsert are also available. The existing picklist editor
568 is unaffected by the extension.
569
570 TIBTreeView is a data aware TCustomTreeView.
571
572 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
573 zero scale will no longer return an error. An Int64 will be returned instead.
574
575 4. TIBTransaction now has events for Before and After Transaction End and a new function
576 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
577
578 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
579 repeated multiple times.
580
581 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
582 check used to get in the way of using Stored Procedures, and "Update or Insert"
583 statements.
584
585 7. Insert, Modify and Delete property Editors now support Query Generation from
586 Stored Procedures.
587
588 8. Three new examples illustrate the use of the new IB Controls
589

591 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
592
593 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
594 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
595 Gabor Boros for reporting this problem and for testing the improvements).
596
597 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
598 See readme.field+param.names in the doc folder.
599
600 3. IBX SQL Editors will now automatically add double quotes around column names when the database
601 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
602
603 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
604
605 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
606 actions.
607
608 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
609 thanks to Yuriy Kopnin for pointing this out).
610
611 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
612
613 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
614 for both fields and parameter setting.
615
616 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
617 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
618
619 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
620 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
621
622 11. TIBTable now has a property editor for "MasterFields"
623
624 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
625 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
626
627 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
628 of settings is unrecognised. Selecting this radio button has no effect on the settings.

631 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
632
633 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
634
635 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
636
637 1. In a TIBCustomDataset descendent, a generator now only sets the value when
638 it is null. This allows for alternative user defined setting of the generator
639
640 Many thanks to Julio Jiménez for this fix
641
642 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
643 and suggests that the user may have forgotten to install it.
644
645 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
646
647 1. Conditional compilation used to limit registration of TIntegerField to
648 Lazarus versions less than 1.1
649
650 2. When a database connection is created, character set is now by default set
651 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
652 1250 to 1254.
653
654
655 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
656
657 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
658
659
660 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
661
662 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
663 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
664
665 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
666 package is changed to do this (which it should do).
667
668 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
669
670 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
671
672 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
673
674 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
675
676 4. Property editors should now correctly resize.
677
678 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
679 (restored original functionality)
680
681 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
682 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
