41 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
42 >   using a simple XML format.
43 >
44 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
45 >   grants to these objects.
46 >
47 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
48 >   dependency problems restoring complex databases.
49 >
50 > 7. TIBXScript: This component has been restructured to allow for the processing of
51 >   embedded XML in INSERT statements and to support interactive sources in addition
52 >   to non-interactive data sources such as files.
53 >
54 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
55 >
56 > 9. TIBXScript: ISQL compatiable Set statements are now supported:

71 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
72 >    fully supported.
73 >
74 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
75 >
76 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
77 >
78 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
79 >
80 > See also doc/IBX4LazarusGuide.pdf for important information on
81 > upgrading to IBX2.
82 >
83 > 1. Size property of TIBStringField is now the width in characters of the field
84 >   and not the byte length. This applies only to multi-byte character sets such
85 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
86 >   code is not recognised as a bug and hence this change to align the behaviour.
87 >   The TStringField change is expected in fpc 3.2.0.
88 >
89 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
90 >   true (default) then Size property value saved in the lfm is ignored. Size is
91 >   always set from the dynamic information read from the database. It is unclear
92 >   why anyone would want to override this and set Size to false.
93 >
94 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
95 >   block.
96 >
97 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
98 >   exist when an attempt is made to connect to it (run time only) then an attempt
99 >   is made to create the database.
100 >
101 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
102 >   has been successfully created as a result of a call to CreateDatabase or when
103 >   creating a database after it was found not to exist.
104 >
105 > 6.  DBControlGrid: a race condition could result in the wrong row image being
106 >    written to the cache. This has been avoided by a trip round the message
107 >    loop before rendering the row image.
108 >
109 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
110 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
111 >    known to risk corrupt rendering of row images when the control is first
112 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
113 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
114 >
115 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
116 >    a TDateEdit control located on an editor panel.
117 >
118 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
119 >
120 > 10. DBControlGrid: Removed memory leak when updating rows.
121 >
122 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
123 >
124 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
125 >
126 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
127 >   when target codepage is CP_NONE. This is a workaround for
128 >   http://bugs.freepascal.org/view.php?id=30622.
129 >
130 > 2. DBLog option removed from TIBStatisticalService - not supported by server
131 >   since Firebird 1.5.
132 >
133 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
134 >   similar.
135 >
136 > 4. IBCodePage: updated mapping between codepages and character id.
137 >
138 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
139 >   Firebird. Character sets with a char width of two are not UTF16.
140 >
141 > 6. Strings received from the database are now always transliterated into UTF8
142 >   regardless of the database character set or connection character set. This
143 >   is for compatibility with the LCL.
144 >
145 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
146 >
147 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
148 >   read in an entire blob just to get the size of the blob. General performance
149 >   improvement when opening datasets containing blobs.
150 >
151 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
152 >
153 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
154 >   is now used.
155 >
156 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
157 >   determined.
158 >
159 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
160 >
161 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
162 >   lazarus 1.6.0
163 >
164 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
165 >   compilation error.
166 >
167 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
168 >
169 > 1. No character set specified for connection: when a text blob is retrieved, the
170 >  character set is determined by looking up the native character set using then
171 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
172 >  set as the connection.
173 >
174 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
175 >   for Login Dialog returing a change to the database path.
176 >
177 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
178 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
179 >   entered value to be saved on a project specific basis (design time only).
180 >
181 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
182 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
183 >   Otherwise, it sets the column text to the selected ListField Value.
184 >
185 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
186 >   column width.
187 >
188 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
189 >   and a case insensitive search is requested.
190 >
191 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
192 >   or column ListSource.
193 >
194 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
195 >   unprepare) when closing and the text has not changed.
196 >
197 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
198 >   Less likely to cause a cursor re-use error on Windows.
199 >
200 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
201 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
202 >
203 > 11. TIBTreeView: Guard against nil destination on record changed
204 >
205 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
206 >    string type with the code page set to reflect the returned field encoding after
207 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
208 >    earlier versions.
209 >
210 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
211 >    will now result in transliteration to the code page specified for the Firebird driver
212 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
213 >
214 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
215 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
216 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
217 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
218 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
219 >    the GETACP is used to determine the Windows code page.
220 >
221 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
222 >    name used as the lc_ctype when the database was opened. Only valid while the
223 >    Database is connected.
224 >
225 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
226 >    id that corresponds to the DefaultCharSetName.
227 >
228 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
229 >
230 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
231 >   path is given and database attach fails due to access permission issues on the
232 >   temp directory or security database, then the attach is retried with "localhost:"
233 >   prefixing the databasename. This should avoid problems when the database has to
234 >   be accessed by a local (e.g. classic) server and libfbembed is used.
235 >
236 > 2. Windows: revised search order for Firebird DLL:
237 >     i.   The Firebird Embedded Server in the application Directory.
238 >     ii.  If the FIREBIRD environment variable is set then the directory this
239 >          points to is searched for the FB Client DLL and then then underlying
240 >          "bin" directory.
241 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
242 >          is used to locate the Firebird installation directory and the underlying
243 >          "bin" directory is searched for the FB Client DLL.
244 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
245 >          are searched for the FB Client DLL.
246 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
247 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
248 >
249 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
250 >   See doc/readme.scriptengine and example applications.
251 >
252 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
253 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
254 >   See dpc/readme.localdatabase and example applications.
255 >
256 > 5. IBDynamicGrid: Reordering on column header click should now also work for
257 >   dynamic columns.
258 >
259 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
260 >   between incrementing/decrementing the lock count and signalling the event.
261 >
262 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
263 >
264 > 1.3.2 was never formally released and only made available as beta copies.
265 >
266 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
267 >
268 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
269 >
270 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
271 >
272 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
273 >   i.e. when it is a calculated field
274 >
275 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
276 >   This problem was due to a race condition between recalculating row heights and
277 >   determining which row was selected by the mouse click. The row height calculation
278 >   is now deferred by an extra trip round the message loop allowing the row to
279 >   be always calculated on the current grid layout rather than risking it being
280 >   calculated on the grid layout after the expanded row has been shrunk.
281 >
282 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
283 >   Windows.
284 >
285 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
286 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
287 >   to be determined at runtime. See doc/readme.charactersets.html.
288 >
289 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
290 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
291 >
292 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
293 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
294 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
295 >
296 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
297 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
298 >   implies no truncation.
299 >
300 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
301 >
302 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
303 >   (avoids "Not in Edit Mode" error).
304 >
305 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
306 >
307 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
308 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
309 >
310 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
311 >
312 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
313 >
314 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
315 >
316 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
317 >
318 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
319 >
320 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
321 >
322 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
323 >     problem with row size when exception is called.
324 >
325 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
326 >
327 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
328 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
329 >
330 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
331 >     keyed in i.e. when autocomplete not performed
332 >
333 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
334 >     console mode applications with all LCL required functions (builtin dialogs and
335 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
336 >     not included in your project, IBX should compile and link with a console mode program.
337 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
338 >     console mode application or the IDE will automatically assume that your
339 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
340 >
341 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
342 >     to use the built in dialogs and cursor management. IBDialogs is
343 >     included by default if "ibexpress" is in your project source's "uses" clause.
344 >     This should be the case for all projects created through the IDE. This is why
345 >     you do not want to add the ibexpress package to console mode applications. The
346 >     ibexpressconsolemode package has been created to allow console mode programs
347 >     to avoid adding LCL dependencies when using IBX, while still having the
348 >     unit search paths set up correctly.
349 >
350 >     Existing users should check to ensure that the "ibexpress" unit is included in
351 >     each project's source file (*.lpr).
352 >
353 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
354 >     exists, you have to first open the package in the IDE and then close it. This
355 >     adds it to the most recently accessed packages list. To make it permanently
356 >     available, add the package name to lazarus' staticpackages.inc file.
357 >
358 >         Thanks to Julio Jiménez for suggesting support of console mode.
359 >
360 > 7.   SQL Parser can now accept quoted strings that include new lines
361 >
362 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
363 >     of text on start of edit. This is particularly useful when tabbing to a
364 >     column and then inserting text.
365 >
366 > 9.   New Examples provided for IB Services and ISQLMonitor.
367 >
368 > 10. Fix error when writing to blob streams that recorded only the last buffer
369 >    write in the blob stream. In most cases, this did not cause a problem as the
370 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
371 >    of a graphic type prefix was lost which caused a problem when the image could
372 >        not be automatically recognised.
373 >
374 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
375 >    already open" errors due to random numbers used for the cursor name being identical.
376 >
377 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
378 >    when opening the table and the Primary Key is the last or only column in the
379 >    table. Thanks to Rick Hoover for the fix.
380 >
381 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
382 >    of "UTF-8", and update list of available database character sets. Existing
383 >    users should check the current lc_ctype setting in their applications.
384 >
385 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
386 >
387 > 1.  Firebird Services: avoid List Index error when opening a service with an
388 >    empty Params property.
389 >
390 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
391 >    Link now set up in Loaded method - avoids occasional failure to apply
392 >    SQL markup on initial open.
393 >
394 > 3.  "Employees" example performance improvements when scrolling.
395 >
396 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
397 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
398 >    random image cached).
399 >
400 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
401 >
402 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
403 >    even when further rows exist.
404 >
405 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
406 >    always be derived from panel height and setting this property can cause confusion.
407 >    Note for existing projects: to avoid a missing property error at run time,
408 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
409 >    in order to remove the property value from the lfm.
410 >
411 >
412 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
413 >
414 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
415 >    call Prepare before setting parameter values.
416 >
417 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.

421 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
422 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
423 >    and "AfterExecQuery". The first three are called after the same event is called

441 >    no action is taken and any unsaved  changes are discarded. This avoids both
442 >    unnecessary overhead and the risk that a validation error may occur in the Post
443 >    raising an exception and thereby preventing a rollback.

445 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
446 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
447 >    width. Display Widths are now corrected by dividing by the max byte width per character.
448 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
449 >    the byte width divided by 4. The byte width of each character set is determined
450 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
451 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).

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

455 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
456 >    control loses focus. Default Key press default interval reduced to 200ms.

458 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
459 >    when dataset rows are less than visible rows.
460 >
461 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
462 >    does not exist or DataSet is empty. More responsive on dataset open. New event
463 >    OnRestorePosition. Column sort disabled if no header row.
464 >
465 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
466 >    while dataset state is dsInsert. Avoids posting errors.
467 >
468 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to

471 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
472 >
473 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
474 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
475 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
476 >    always "posts" the current record regardless or whether or not it may be more appropriate
477 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
478 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
479 >    as the first action of the "Post" method and allows the handler to convert the Post
480 >    into a Cancel if that is the appropriate action on moving to a different row. This is
481 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
482 >    raised here, but it may still be more appropriate to validate a post and signal
483 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
484 >
485 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
486 >    separated list. Each library name on the list is tried in turn, in left to right
487 >    order with the first found being used as the firebird library. By default, on Linux,
488 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
489 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
490 >
491 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
492 >    then it will still attempt to access the database via the Firebird Server and will
493 >    require a username and password. If only the pathname is given, then the username
494 >    and password should be omitted and the unix file permissions are used to grant

499   1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
500      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
501      that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
502 <    correspondes to a row of the linked DataSource. Any data aware control on the
502 >    corresponds to a row of the linked DataSource. Any data aware control on the
503      replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
504  
505   2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
506 <   When set to false (default true), the Hour Glass cursor is surpressed and no cursor change
506 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
507     takes place during database access. This may be useful when there are performance issues with
508     the change of cursor. Setting the property to false suppresses the change of cursor.

525   1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
526     This is typically used during an "OnBeforeOpen" event handler to manipulate the
# Line 38 | Line 538 | IBX Change Log  version
538     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
539     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
540     to revise the available list and restrict it to items that are prefixed by the
541 <   typed text (either case sensitive or case insenstive). Autoinsert allows a
541 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
542     newly typed entry to be added to the list dataset and included in the available
543     list items.
