2 >
3 > 1. IBExtract: Identity columns - add addition check for null column for generator name.
4 >
5 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
6 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
7 >   information). Values returned as a result of executing an Insert or Update statement
8 >   replace existing values in the current row for each corresponding column.
9 >
10 > 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
11 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
12 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
13 >   each Identity column after the insert is executed.
14 >
15 > 4. TIBGenerator: small performance improvement by not preparing query each time
16 >   a new number is generated.
17 >
18 > 5. TIBSQL: Free resources when transaction changed.
19 >
20 > 6. Property editor will now sync table name to a System Table when "Include System
21 >   Tables" is selected and the query is for a System Table.
22 >
23 > 7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
24 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
25 >   Insert..Returning clause.
26 >
27 > 8. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
28 >   values are no longer converted to milliseconds from TDateTime and then back again
29 >   the TDateTime (the TDataset approach).
30 >
31 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
32 >
33 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
34 >   changes.
35 >
36 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
37 >   Bug could result in truncated multi-byte character set values.
38 >
39 > 3. Changes consequential on moving fbintf character set utility functions from
40 >   IFirebirdAPI to IAttachment.
41 >
42 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
43 >
44 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
45 >   results in autocomplete ignoring prefix text.
46 >
47 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
48 >   entering a new name into the text box.
49 >
50 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
51 >   Firebird rather than recomputing it.
52 >
53 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
54 >   screen centre. Previously some were "poDesigned" which may be inappropriate
55 >   for multi monitor desktops.
56 >
57 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
58 >
59 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
60 >    a transaction and always reset the object.
61 >
62 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
63 >
64 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
65 >
66 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
67 >    to a gbak format archive.
68 >
69 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
70 >
71 > 16. IBLocaldb: Drop database if error creating an empty database.
72 >
73 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
74 >    unless selected node not in current dataset.
75 >
76 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
77 >    to TIBCustomService, and IBlocalDB code tidy up.
78 >
79 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
80 >    behaviour due to uninitialised variable.
81 >
82 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
83 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
84 >
85 > 21. IBSQL: When Database changed ensure that all resources are freed.
86 >
87 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
88 >
89 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
90 >    * Line Wrap on SQL Token boundaries (on user command)
91 >    * auto-complete table names in drop down list of table names
92 >    * Double click on tablename or field name adds to SQL text
93 >
94 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
95 >
96 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
97 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
98 >    workaround for a problem in fpc 3.0.4 win64).
99 >
100 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
101 >
102 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
103 >
104 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
105 >
106 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
107 >   include remote system name.
108 >
109 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
110 >   tables when data included in output.
111 >
112 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
113 >   and timing information to be written to stdout. This may be used to locate
114 >   performance bottlenecks.
115 >
116 > 4. SQLParser: only call "OnChanging" event handler when value is different.
117 >
118 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
119 >
120 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
121 >   that BindFields is called when the query is next activated. Avoids FieldName
122 >   not found error.
123 >
124 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
125 >   purpose and allows the programmer to define any action they want for Update, Insert
126 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
127 >   filtering of updates, or use of statements such as Grant or Revoke instead of
128 >   normal DML. See User Manual for more information.
129 >
130 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
131 >
132 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
133 >
134 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
135 >
136 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
137 >   hexadecimal notation.
138 >
139 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
140 >   using a simple XML format.
141 >
142 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
143 >   grants to these objects.
144 >
145 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
146 >   dependency problems restoring complex databases.
147 >
148 > 7. TIBXScript: This component has been restructured to allow for the processing of
149 >   embedded XML in INSERT statements and to support interactive sources in addition
150 >   to non-interactive data sources such as files.
151 >
152 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
153 >
154 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
155 >   SET SQL DIALECT
156 >   SET TERM
157 >   SET AUTODDL
158 >   SET BAIL
159 >   SET ECHO
160 >   SET COUNT
161 >   SET STATS
162 >   SET NAMES <character set>
163 >
164 > 10. IBVersion unit added to hold current IBX Version Number information.
165 >
166 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
167 >    and domain definitions.
168 >
169 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
170 >    fully supported.
171 >
172 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
173 >
174 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
175 >
176 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
177 >
178 > See also doc/IBX4LazarusGuide.pdf for important information on
179 > upgrading to IBX2.
180 >
181 > 1. Size property of TIBStringField is now the width in characters of the field
182 >   and not the byte length. This applies only to multi-byte character sets such
183 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
184 >   code is not recognised as a bug and hence this change to align the behaviour.
185 >   The TStringField change is expected in fpc 3.2.0.
186 >
187 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
188 >   true (default) then Size property value saved in the lfm is ignored. Size is
189 >   always set from the dynamic information read from the database. It is unclear
190 >   why anyone would want to override this and set Size to false.
191 >
192 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
193 >   block.
194 >
195 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
196 >   exist when an attempt is made to connect to it (run time only) then an attempt
197 >   is made to create the database.
198 >
199 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
200 >   has been successfully created as a result of a call to CreateDatabase or when
201 >   creating a database after it was found not to exist.
202 >
203 > 6.  DBControlGrid: a race condition could result in the wrong row image being
204 >    written to the cache. This has been avoided by a trip round the message
205 >    loop before rendering the row image.
206 >
207 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
208 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
209 >    known to risk corrupt rendering of row images when the control is first
210 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
211 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
212 >
213 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
214 >    a TDateEdit control located on an editor panel.
215 >
216 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
217 >
218 > 10. DBControlGrid: Removed memory leak when updating rows.
219 >
220 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
221 >
222 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
223 >
224 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
225 >   when target codepage is CP_NONE. This is a workaround for
226 >   http://bugs.freepascal.org/view.php?id=30622.
227 >
228 > 2. DBLog option removed from TIBStatisticalService - not supported by server
229 >   since Firebird 1.5.
230 >
231 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
232 >   similar.
233 >
234 > 4. IBCodePage: updated mapping between codepages and character id.
235 >
236 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
237 >   Firebird. Character sets with a char width of two are not UTF16.
238 >
239 > 6. Strings received from the database are now always transliterated into UTF8
240 >   regardless of the database character set or connection character set. This
241 >   is for compatibility with the LCL.
242 >
243 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
244 >
245 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
246 >   read in an entire blob just to get the size of the blob. General performance
247 >   improvement when opening datasets containing blobs.
248 >
249 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
250 >
251 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
252 >   is now used.
253 >
254 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
255 >   determined.
256 >
257 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
258 >
259 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
260 >   lazarus 1.6.0
261 >
262 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
263 >   compilation error.
264 >
265 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
266 >
267 > 1. No character set specified for connection: when a text blob is retrieved, the
268 >  character set is determined by looking up the native character set using then
269 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
270 >  set as the connection.
271 >
272 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
273 >   for Login Dialog returing a change to the database path.
274 >
275 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
276 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
277 >   entered value to be saved on a project specific basis (design time only).
278 >
279 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
280 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
281 >   Otherwise, it sets the column text to the selected ListField Value.
282 >
283 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
284 >   column width.
285 >
286 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
287 >   and a case insensitive search is requested.
288 >
289 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
290 >   or column ListSource.
291 >
292 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
293 >   unprepare) when closing and the text has not changed.
294 >
295 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
296 >   Less likely to cause a cursor re-use error on Windows.
297 >
298 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
299 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
300 >
301 > 11. TIBTreeView: Guard against nil destination on record changed
302 >
303 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
304 >    string type with the code page set to reflect the returned field encoding after
305 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
306 >    earlier versions.
307 >
308 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
309 >    will now result in transliteration to the code page specified for the Firebird driver
310 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
311 >
312 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
313 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
314 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
315 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
316 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
317 >    the GETACP is used to determine the Windows code page.
318 >
319 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
320 >    name used as the lc_ctype when the database was opened. Only valid while the
321 >    Database is connected.
322 >
323 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
324 >    id that corresponds to the DefaultCharSetName.
325 >
326 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
327 >
328 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
329 >   path is given and database attach fails due to access permission issues on the
330 >   temp directory or security database, then the attach is retried with "localhost:"
331 >   prefixing the databasename. This should avoid problems when the database has to
332 >   be accessed by a local (e.g. classic) server and libfbembed is used.
333 >
334 > 2. Windows: revised search order for Firebird DLL:
335 >     i.   The Firebird Embedded Server in the application Directory.
336 >     ii.  If the FIREBIRD environment variable is set then the directory this
337 >          points to is searched for the FB Client DLL and then then underlying
338 >          "bin" directory.
339 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
340 >          is used to locate the Firebird installation directory and the underlying
341 >          "bin" directory is searched for the FB Client DLL.
342 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
343 >          are searched for the FB Client DLL.
344 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
345 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
346 >
347 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
348 >   See doc/readme.scriptengine and example applications.
349 >
350 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
351 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
352 >   See dpc/readme.localdatabase and example applications.
353 >
354 > 5. IBDynamicGrid: Reordering on column header click should now also work for
355 >   dynamic columns.
356 >
357 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
358 >   between incrementing/decrementing the lock count and signalling the event.
359 >
360 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
361 >
362 > 1.3.2 was never formally released and only made available as beta copies.
363 >
364 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
365 >
366 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
367 >
368 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
369 >
370 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
371 >   i.e. when it is a calculated field
372 >
373 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
374 >   This problem was due to a race condition between recalculating row heights and
375 >   determining which row was selected by the mouse click. The row height calculation
376 >   is now deferred by an extra trip round the message loop allowing the row to
377 >   be always calculated on the current grid layout rather than risking it being
378 >   calculated on the grid layout after the expanded row has been shrunk.
379 >
380 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
381 >   Windows.
382 >
383 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
384 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
385 >   to be determined at runtime. See doc/readme.charactersets.html.
386 >
387 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
388 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
389 >
390 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
391 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
392 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
393 >
394 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
395 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
396 >   implies no truncation.
397 >
398 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
399 >
400 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
401 >   (avoids "Not in Edit Mode" error).
402 >
403 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
404 >
405 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
406 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
407 >
408 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
409 >
410 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
411 >
412 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
413 >
414 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
415 >
416 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
417 >
418 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
419 >
420 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
421 >     problem with row size when exception is called.
422 >

526 >    an indicator can be set that shows the user that in order to save changes,

533 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
534 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
535 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
536 >    then IBX will attempt to post any unsaved changes before the dataset is closed
537 >    (and after the BeforeClose event handler is called). The exception is when the
538 >    dataset is being closed as a result of a transaction rollback. In this case,
539 >    no action is taken and any unsaved  changes are discarded. This avoids both
540 >    unnecessary overhead and the risk that a validation error may occur in the Post
541 >    raising an exception and thereby preventing a rollback.
542 >
543 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
544 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
545 >    width. Display Widths are now corrected by dividing by the max byte width per character.
546 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
547 >    the byte width divided by 4. The byte width of each character set is determined
548 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
549 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).

551 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.

553 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
554 >    control loses focus. Default Key press default interval reduced to 200ms.
555 >
556 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
557 >    when dataset rows are less than visible rows.
558 >
559 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
560 >    does not exist or DataSet is empty. More responsive on dataset open. New event
561 >    OnRestorePosition. Column sort disabled if no header row.
562 >
563 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
564 >    while dataset state is dsInsert. Avoids posting errors.
565 >
566 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to

568 >
569 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
570 >
571 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
572 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
573 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
574 >    always "posts" the current record regardless or whether or not it may be more appropriate
575 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
576 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
577 >    as the first action of the "Post" method and allows the handler to convert the Post
578 >    into a Cancel if that is the appropriate action on moving to a different row. This is
579 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
580 >    raised here, but it may still be more appropriate to validate a post and signal
581 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
582 >
583 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
584 >    separated list. Each library name on the list is tried in turn, in left to right
585 >    order with the first found being used as the firebird library. By default, on Linux,
586 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be

588 >
589 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"

603   2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
604 <   When set to false (default true), the Hour Glass cursor is surpressed and no cursor change
604 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
605     takes place during database access. This may be useful when there are performance issues with
606     the change of cursor. Setting the property to false suppresses the change of cursor.

636     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
637     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
638     to revise the available list and restrict it to items that are prefixed by the
639 <   typed text (either case sensitive or case insenstive). Autoinsert allows a
639 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
