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

421 + IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
422 +
423 + 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
424 +    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
425 +    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
426 +    corresponds to a row of the linked DataSource. Any data aware control on the
427 +    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
428 +
429 + 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
430 +   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
431 +   takes place during database access. This may be useful when there are performance issues with
432 +   the change of cursor. Setting the property to false suppresses the change of cursor.
433 +
434 + 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
435 +   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
436 +   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
437 +   making all changes permanent immediately rather than when the transaction is explicitly
438 +   committed.
439 +
440 + 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
441 +   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

447 + IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
448 +
449 + 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
450 +   This is typically used during an "OnBeforeOpen" event handler to manipulate the
451 +   "Where" and "Having" clauses to implement user specified filters of arbitrary
452 +   complexity.
453 +
454 + 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
455 +   three new data aware controls dependent on IBX and which make use of the SQL Parser.
456 +   These are:
457 +
458 +   - TIBLookupComboEditBox
459 +   - TIBDynamicGrid
460 +   - TIBTreeview
461 +
462 +   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
463 +   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
464 +   to revise the available list and restrict it to items that are prefixed by the
465 +   typed text (either case sensitive or case insensitive). Autoinsert allows a
466 +   newly typed entry to be added to the list dataset and included in the available
467 +   list items.
468 +
469 +   TIBDynamicGrid is a TDBGrid descendent that provides for:
470 +   - automatic resizing of selected columns to fill the available row length
471 +   - automatic positioning and sizing of a "totals" control, typically at the
472 +     column footer, on a per column basis.
473 +   - DataSet resorting on header row click, sorting the dataset by the selected column.
474 +     A second click on the same header cell reversed the sort order.
475 +   - Support for a "Panel Editor". That is on clicking the indicator column, the row
476 +     is automatically expanded and a panel superimposed on it. The panel can have any
477 +     number of child controls, typically data aware controls with the same datasource
478 +     as the grid allowing for editing of additional fields and more complex editors.
479 +   - Reselection of the same row following resorting.
480 +   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
481 +     Its properties are specified on a per column basis and allows for one or more
482 +     columns to have their values selected from a list provided by a dataset.
483 +     Autocomplete and autoinsert are also available. The existing picklist editor
484 +     is unaffected by the extension.
485 +
486 +   TIBTreeView is a data aware TCustomTreeView.
487 +
488 + 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
489 +   zero scale will no longer return an error. An Int64 will be returned instead.
490 +
491 + 4. TIBTransaction now has events for Before and After Transaction End and a new function
492 +   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
493 +
494 + 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
495 +   repeated multiple times.
496 +
497 + 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
498 +   check used to get in the way of using Stored Procedures, and "Update or Insert"
499 +   statements.
500 +
501 + 7. Insert, Modify and Delete property Editors now support Query Generation from
502 +   Stored Procedures.
503 +
504 + 8. Three new examples illustrate the use of the new IB Controls
505 +
506 +
507 + IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
508 +
509 + 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
510 +   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
511 +   Gabor Boros for reporting this problem and for testing the improvements).
512 +
513 + 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
514 +   See readme.field+param.names in the doc folder.
515 +
516 + 3. IBX SQL Editors will now automatically add double quotes around column names when the database
517 +   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
518 +
519 + 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
520 +
521 + 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
522 +   actions.
523 +
524 + 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
525 +   thanks to Yuriy Kopnin for pointing this out).
526 +
527 + 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
528 +
529 + 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
530 +   for both fields and parameter setting.
531 +
532 + 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
533 +   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
534 +
535 + 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
536 +    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
537 +
538 + 11. TIBTable now has a property editor for "MasterFields"
539 +
540 + 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
541 +    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
542 +
543 + 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
544 +    of settings is unrecognised. Selecting this radio button has no effect on the settings.
545 +  
546 +
