1 > IBX Change Log  version                           (2.1-0) Fri, 15 Dec 2017 12:20:11 +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 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
24 >   screen centre. Previously some were "poDesigned" which may be inappropriate
25 >   for multi monitor desktops.
26 >
27 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
28 >
29 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
30 >    a transaction and always reset the object.
31 >
32 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
33 >
34 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
35 >
36 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
37 >    to a gbak format archive.
38 >
39 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
40 >
41 > 16. IBLocaldb: Drop database if error creating an empty database.
42 >
43 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
44 >    unless selected node not in current dataset.
45 >
46 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
47 >    to TIBCustomService, and IBlocalDB code tidy up.
48 >
49 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
50 >    behaviour due to uninitialised variable.
51 >
52 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
53 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
54 >
55 > 21. IBSQL: When Database changed ensure that all resources are freed.
56 >
57 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
58 >
59 > 23. SQL Property Editors now use SynEdit with SQL Highlighter.
60 >
61 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
62 >
63 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
64 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
65 >    workaround for a problem in fpc 3.0.4 win64).
66 >
67 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
68 >
69 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
70 >
71 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
72 >   include remote system name.
73 >
74 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
75 >   tables when data included in output.
76 >
77 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
78 >   and timing information to be written to stdout. This may be used to locate
79 >   performance bottlenecks.
80 >
81 > 4. SQLParser: only call "OnChanging" event handler when value is different.
82 >
83 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
84 >
85 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
86 >   that BindFields is called when the query is next activated. Avoids FieldName
87 >   not found error.
88 >
89 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
90 >   purpose and allows the programmer to define any action they want for Update, Insert
91 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
92 >   filtering of updates, or use of statements such as Grant or Revoke instead of
93 >   normal DML. See User Manual for more information.
94 >
95 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
96 >
97 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
98 >
99 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
100 >
101 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
102 >   hexadecimal notation.
103 >
104 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
105 >   using a simple XML format.
106 >
107 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
108 >   grants to these objects.
109 >
110 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
111 >   dependency problems restoring complex databases.
112 >
113 > 7. TIBXScript: This component has been restructured to allow for the processing of
114 >   embedded XML in INSERT statements and to support interactive sources in addition
115 >   to non-interactive data sources such as files.
116 >
117 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
118 >
119 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
120 >   SET SQL DIALECT
121 >   SET TERM
122 >   SET AUTODDL
123 >   SET BAIL
124 >   SET ECHO
125 >   SET COUNT
126 >   SET STATS
127 >   SET NAMES <character set>
128 >
129 > 10. IBVersion unit added to hold current IBX Version Number information.
130 >
131 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
132 >    and domain definitions.
133 >
134 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
135 >    fully supported.
136 >
137 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
138 >
139 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
140 >
141 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
142 >
143 > See also doc/IBX4LazarusGuide.pdf for important information on
144 > upgrading to IBX2.
145 >
146 > 1. Size property of TIBStringField is now the width in characters of the field
147 >   and not the byte length. This applies only to multi-byte character sets such
148 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
149 >   code is not recognised as a bug and hence this change to align the behaviour.
150 >   The TStringField change is expected in fpc 3.2.0.
151 >
152 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
153 >   true (default) then Size property value saved in the lfm is ignored. Size is
154 >   always set from the dynamic information read from the database. It is unclear
155 >   why anyone would want to override this and set Size to false.
156 >
157 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
158 >   block.
159 >
160 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
161 >   exist when an attempt is made to connect to it (run time only) then an attempt
162 >   is made to create the database.
163 >
164 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
165 >   has been successfully created as a result of a call to CreateDatabase or when
166 >   creating a database after it was found not to exist.
167 >
168 > 6.  DBControlGrid: a race condition could result in the wrong row image being
169 >    written to the cache. This has been avoided by a trip round the message
170 >    loop before rendering the row image.
171 >
172 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
173 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
174 >    known to risk corrupt rendering of row images when the control is first
175 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
176 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
177 >
178 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
179 >    a TDateEdit control located on an editor panel.
180 >
181 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
182 >
183 > 10. DBControlGrid: Removed memory leak when updating rows.
184 >
185 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
186 >
187 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
188 >
189 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
190 >   when target codepage is CP_NONE. This is a workaround for
191 >   http://bugs.freepascal.org/view.php?id=30622.
192 >
193 > 2. DBLog option removed from TIBStatisticalService - not supported by server
194 >   since Firebird 1.5.
195 >
196 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
197 >   similar.
198 >
199 > 4. IBCodePage: updated mapping between codepages and character id.
200 >
201 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
202 >   Firebird. Character sets with a char width of two are not UTF16.
203 >
204 > 6. Strings received from the database are now always transliterated into UTF8
205 >   regardless of the database character set or connection character set. This
206 >   is for compatibility with the LCL.
207 >
208 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
209 >
210 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
211 >   read in an entire blob just to get the size of the blob. General performance
212 >   improvement when opening datasets containing blobs.
213 >
214 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
215 >
216 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
217 >   is now used.
218 >
219 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
220 >   determined.
221 >
222 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
223 >
224 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
225 >   lazarus 1.6.0
226 >
227 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
228 >   compilation error.
229 >
230 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
231 >
232 > 1. No character set specified for connection: when a text blob is retrieved, the
233 >  character set is determined by looking up the native character set using then
234 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
235 >  set as the connection.
236 >
237 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
238 >   for Login Dialog returing a change to the database path.
239 >
240 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
241 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
242 >   entered value to be saved on a project specific basis (design time only).
243 >
244 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
245 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
246 >   Otherwise, it sets the column text to the selected ListField Value.
247 >
248 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
249 >   column width.
250 >
251 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
252 >   and a case insensitive search is requested.
253 >
254 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
255 >   or column ListSource.
256 >
257 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
258 >   unprepare) when closing and the text has not changed.
259 >
260 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
261 >   Less likely to cause a cursor re-use error on Windows.
262 >
263 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
264 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
265 >
266 > 11. TIBTreeView: Guard against nil destination on record changed
267 >
268 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
269 >    string type with the code page set to reflect the returned field encoding after
270 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
271 >    earlier versions.
272 >
273 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
274 >    will now result in transliteration to the code page specified for the Firebird driver
275 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
276 >
277 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
278 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
279 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
280 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
281 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
282 >    the GETACP is used to determine the Windows code page.
283 >
284 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
285 >    name used as the lc_ctype when the database was opened. Only valid while the
286 >    Database is connected.
287 >
288 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
289 >    id that corresponds to the DefaultCharSetName.
290 >
291 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
292 >
293 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
294 >   path is given and database attach fails due to access permission issues on the
295 >   temp directory or security database, then the attach is retried with "localhost:"
296 >   prefixing the databasename. This should avoid problems when the database has to
297 >   be accessed by a local (e.g. classic) server and libfbembed is used.
298 >
299 > 2. Windows: revised search order for Firebird DLL:
300 >     i.   The Firebird Embedded Server in the application Directory.
301 >     ii.  If the FIREBIRD environment variable is set then the directory this
302 >          points to is searched for the FB Client DLL and then then underlying
303 >          "bin" directory.
304 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
305 >          is used to locate the Firebird installation directory and the underlying
306 >          "bin" directory is searched for the FB Client DLL.
307 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
308 >          are searched for the FB Client DLL.
309 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
310 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
311 >
312 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
313 >   See doc/readme.scriptengine and example applications.
314 >
315 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
316 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
317 >   See dpc/readme.localdatabase and example applications.
318 >
319 > 5. IBDynamicGrid: Reordering on column header click should now also work for
320 >   dynamic columns.
321 >
322 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
323 >   between incrementing/decrementing the lock count and signalling the event.
324 >
325 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
326 >
327 > 1.3.2 was never formally released and only made available as beta copies.
328 >
329 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
330 >
331 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
332 >
333 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
334 >
335 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
336 >   i.e. when it is a calculated field
337 >
338 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
339 >   This problem was due to a race condition between recalculating row heights and
340 >   determining which row was selected by the mouse click. The row height calculation
341 >   is now deferred by an extra trip round the message loop allowing the row to
342 >   be always calculated on the current grid layout rather than risking it being
343 >   calculated on the grid layout after the expanded row has been shrunk.
344 >
345 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
346 >   Windows.
347 >
348 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
349 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
350 >   to be determined at runtime. See doc/readme.charactersets.html.
351 >
352 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
353 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
354 >
355 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
356 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
357 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
358 >
359 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
360 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
361 >   implies no truncation.
362 >
363 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
364 >
365 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
366 >   (avoids "Not in Edit Mode" error).
367 >
368 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
369 >
370 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
371 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
372 >
373 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
374 >
375 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
376 >
377 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
378 >
379 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
380 >
381 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
382 >
383 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
384 >
385 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
386 >     problem with row size when exception is called.
387 >
388 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
389 >
390 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
391 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
392 >
393 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
394 >     keyed in i.e. when autocomplete not performed
395 >
396 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
397 >     console mode applications with all LCL required functions (builtin dialogs and
398 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
399 >     not included in your project, IBX should compile and link with a console mode program.
400 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
401 >     console mode application or the IDE will automatically assume that your
402 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
403 >
404 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
405 >     to use the built in dialogs and cursor management. IBDialogs is
406 >     included by default if "ibexpress" is in your project source's "uses" clause.
407 >     This should be the case for all projects created through the IDE. This is why
408 >     you do not want to add the ibexpress package to console mode applications. The
409 >     ibexpressconsolemode package has been created to allow console mode programs
410 >     to avoid adding LCL dependencies when using IBX, while still having the
411 >     unit search paths set up correctly.
412 >
413 >     Existing users should check to ensure that the "ibexpress" unit is included in
414 >     each project's source file (*.lpr).
415 >
416 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
417 >     exists, you have to first open the package in the IDE and then close it. This
418 >     adds it to the most recently accessed packages list. To make it permanently
419 >     available, add the package name to lazarus' staticpackages.inc file.
420 >

484 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
485 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
486 >    and "AfterExecQuery". The first three are called after the same event is called
487 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
488 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
489 >    enable monitoring of transaction status changes for a given transaction to be
490 >    handled in a single place. For example, when a change to the dataset occurs
491 >    an indicator can be set that shows the user that in order to save changes,
492 >    the transaction should be committed.  Rather than doing this per dataset, this
493 >    can now be done per transaction.
494 >
495 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
496 >    the dataset is scrolled. However, any changes to the current row are, by default,
497 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
498 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
499 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
500 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
501 >    then IBX will attempt to post any unsaved changes before the dataset is closed
502 >    (and after the BeforeClose event handler is called). The exception is when the
503 >    dataset is being closed as a result of a transaction rollback. In this case,
504 >    no action is taken and any unsaved  changes are discarded. This avoids both
505 >    unnecessary overhead and the risk that a validation error may occur in the Post
506 >    raising an exception and thereby preventing a rollback.
507 >
508 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
509 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
510 >    width. Display Widths are now corrected by dividing by the max byte width per character.
511 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
512 >    the byte width divided by 4. The byte width of each character set is determined
513 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
514 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
515 >
516 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
517 >
518 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
519 >    control loses focus. Default Key press default interval reduced to 200ms.
520 >
521 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
522 >    when dataset rows are less than visible rows.
523 >
524 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
525 >    does not exist or DataSet is empty. More responsive on dataset open. New event
526 >    OnRestorePosition. Column sort disabled if no header row.
527 >
528 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
529 >    while dataset state is dsInsert. Avoids posting errors.
530 >
531 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
532 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
533 >
534 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
535 >
536 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
537 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
538 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
539 >    always "posts" the current record regardless or whether or not it may be more appropriate
540 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
541 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
542 >    as the first action of the "Post" method and allows the handler to convert the Post
543 >    into a Cancel if that is the appropriate action on moving to a different row. This is
544 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
545 >    raised here, but it may still be more appropriate to validate a post and signal
546 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
547 >
548 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
549 >    separated list. Each library name on the list is tried in turn, in left to right
550 >    order with the first found being used as the firebird library. By default, on Linux,
551 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
552 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
553 >
554 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
555 >    then it will still attempt to access the database via the Firebird Server and will
556 >    require a username and password. If only the pathname is given, then the username
557 >    and password should be omitted and the unix file permissions are used to grant

562 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
563 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
564 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
565 >    corresponds to a row of the linked DataSource. Any data aware control on the
566 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
567 >
568 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
569 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
570 >   takes place during database access. This may be useful when there are performance issues with
571 >   the change of cursor. Setting the property to false suppresses the change of cursor.
572 >
573 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
574 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
575 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
576 >   making all changes permanent immediately rather than when the transaction is explicitly
577 >   committed.

579 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
580 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

588   1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
589     This is typically used during an "OnBeforeOpen" event handler to manipulate the
# Line 16 | Line 601 | IBX Change Log  version
601     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
602     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
603     to revise the available list and restrict it to items that are prefixed by the
604 <   typed text (either case sensitive or case insenstive). Autoinsert allows a
604 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
605     newly typed entry to be added to the list dataset and included in the available
606     list items.
