43 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
44 >   using a simple XML format.
45 >
46 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
47 >   grants to these objects.
48 >
49 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
50 >   dependency problems restoring complex databases.
51 >
52 > 7. TIBXScript: This component has been restructured to allow for the processing of
53 >   embedded XML in INSERT statements and to support interactive sources in addition
54 >   to non-interactive data sources such as files.
55 >
56 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
57 >
58 > 9. TIBXScript: ISQL compatiable Set statements are now supported:

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

423 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
424 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"

436 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
437 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
438 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
439 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
440 >    then IBX will attempt to post any unsaved changes before the dataset is closed
441 >    (and after the BeforeClose event handler is called). The exception is when the
442 >    dataset is being closed as a result of a transaction rollback. In this case,
443 >    no action is taken and any unsaved  changes are discarded. This avoids both
444 >    unnecessary overhead and the risk that a validation error may occur in the Post

448 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character

450 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
451 >    the byte width divided by 4. The byte width of each character set is determined
452 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
453 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).

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

463 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource

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

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

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