2 tony 45
3 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
4 tony 45
5 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
6    
7     3. TIBExtract: data formatted as Charset set "octets" is now output using
8     hexadecimal notation.
9    
10     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
11     using a simple XML format.
12    
13     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
14     grants to these objects.
15    
16     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
17     dependency problems restoring complex databases.
18    
19     7. TIBXScript: This component has been restructured to allow for the processing of
20     embedded XML in INSERT statements and to support interactive sources in addition
21     to non-interactive data sources such as files.
22    
23     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
24    
25     9. TIBXScript: ISQL compatiable Set statements are now supported:
26     SET SQL DIALECT
27     SET TERM
28     SET AUTODDL
29     SET BAIL
30     SET ECHO
31     SET COUNT
32     SET STATS
33     SET NAMES <character set>
34    
35     10. IBVersion unit added to hold current IBX Version Number information.
36    
37     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
38     and domain definitions.
39    
40     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
41     fully supported.
42    
43     13. TIBExtract: when a database dump includes data, the generator values are now also set.
44    
45     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
46

48    
49 tony 45 See also doc/readme.upgrade-4-x.to.2-0-0.xhtml for important information on
50     upgrading to IBX2.
51    
52     1. Size property of TIBStringField is now the width in characters of the field
53     and not the byte length. This applies only to multi-byte character sets such
54     as UTF8. The original approach aligned with TStringField. However, the TStringField
55     code is not recognised as a bug and hence this change to align the behaviour.
56     The TStringField change is expected in fpc 3.2.0.
57    
58     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
59     true (default) then Size property value saved in the lfm is ignored. Size is
60     always set from the dynamic information read from the database. It is unclear
61     why anyone would want to override this and set Size to false.
62    
63     3. ibxscript: should now handle correctly a Case..End statement within a procedure
64     block.
65    
66     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
67     exist when an attempt is made to connect to it (run time only) then an attempt
68     is made to create the database.
69    
70     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
71     has been successfully created as a result of a call to CreateDatabase or when
72     creating a database after it was found not to exist.
73    
74     6. DBControlGrid: a race condition could result in the wrong row image being
75     written to the cache. This has been avoided by a trip round the message
76     loop before rendering the row image.
77    
78     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
79     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
80     known to risk corrupt rendering of row images when the control is first
81     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
82     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
83    
84     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
85     a TDateEdit control located on an editor panel.
86    
87     9. TIBExtract: brought up-to-date plus many bug fixes.
88    
89     10. DBControlGrid: Removed memory leak when updating rows.
90    
91     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
92    
93 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
94    
95     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
96     when target codepage is CP_NONE. This is a workaround for
97     http://bugs.freepascal.org/view.php?id=30622.
98    
99     2. DBLog option removed from TIBStatisticalService - not supported by server
100     since Firebird 1.5.
101    
102     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
103     similar.
104    
105     4. IBCodePage: updated mapping between codepages and character id.
106    
107     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
108     Firebird. Character sets with a char width of two are not UTF16.
109    
110     6. Strings received from the database are now always transliterated into UTF8
111     regardless of the database character set or connection character set. This
112     is for compatibility with the LCL.
113    
114 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
115 tony 41
116     1. IBBlob: Defer reading of blob until read method called. This avoids having to
117     read in an entire blob just to get the size of the blob. General performance
118     improvement when opening datasets containing blobs.
119    
120     2. Clearing a Blob now sets the corresponding field's modified flag.
121    
122     3. IBLookupCombo: When not performing auto-complete, original query sort order
123     is now used.
124    
125     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
126     determined.
127    
128     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
129    
130     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
131     lazarus 1.6.0
132    
133     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
134     compilation error.
135    
136 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
137    
138     1. No character set specified for connection: when a text blob is retrieved, the
139     character set is determined by looking up the native character set using then
140     Firebird API. Otherwise a text mode blob is assumed to have the same character
141     set as the connection.
142    
143     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
144     for Login Dialog returing a change to the database path.
145    
146     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
147     to be changed from that given in the TIBDatabase/TIBServer component and for the
148     entered value to be saved on a project specific basis (design time only).
149    
150     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
151     column fieldname. If they are the same then it is acts as a look up for the KeyValue
152     Otherwise, it sets the column text to the selected ListField Value.
153    
154     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
155     column width.
156    
157     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
158     and a case insensitive search is requested.
159    
160     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
161     or column ListSource.
162    
163     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
164     unprepare) when closing and the text has not changed.
165    
166     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
167     Less likely to cause a cursor re-use error on Windows.
168    
169     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
170     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
171    
172     11. TIBTreeView: Guard against nil destination on record changed
173    
174     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
175     string type with the code page set to reflect the returned field encoding after
176     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
177     earlier versions.
178    
179     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
180     will now result in transliteration to the code page specified for the Firebird driver
181     if the assigned string has a different code page. FPC 3.0.0 onwards only.
182    
183     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
184     is ignored and the lc_ctype value, when the database is opened, is set to align with
185     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
186     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
187     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
188     the GETACP is used to determine the Windows code page.
189    
190     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
191     name used as the lc_ctype when the database was opened. Only valid while the
192     Database is connected.
193    
194     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
195     id that corresponds to the DefaultCharSetName.
196    
197 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
198    
199     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
200     path is given and database attach fails due to access permission issues on the
201     temp directory or security database, then the attach is retried with "localhost:"
202     prefixing the databasename. This should avoid problems when the database has to
203     be accessed by a local (e.g. classic) server and libfbembed is used.
204    
205     2. Windows: revised search order for Firebird DLL:
206     i. The Firebird Embedded Server in the application Directory.
207     ii. If the FIREBIRD environment variable is set then the directory this
208     points to is searched for the FB Client DLL and then then underlying
209     "bin" directory.
210     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
211     is used to locate the Firebird installation directory and the underlying
212     "bin" directory is searched for the FB Client DLL.
213     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
214     are searched for the FB Client DLL.
215     v. The PATH Environment variable is used to search for the FB Client DLL.
216     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
217    
218     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
219     See doc/readme.scriptengine and example applications.
220    
221     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
222     simplify the use of the embedded firebird server on both Linux and Windows platforms.
223     See dpc/readme.localdatabase and example applications.
224    
225     5. IBDynamicGrid: Reordering on column header click should now also work for
226     dynamic columns.
227    
228     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
229     between incrementing/decrementing the lock count and signalling the event.
230    
231 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
232    
233 tony 37 1.3.2 was never formally released and only made available as beta copies.
234    
235 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
236    
237     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
238    
239     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
240    
241     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
242     i.e. when it is a calculated field
243    
244     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
245     This problem was due to a race condition between recalculating row heights and
246     determining which row was selected by the mouse click. The row height calculation
247     is now deferred by an extra trip round the message loop allowing the row to
248     be always calculated on the current grid layout rather than risking it being
249     calculated on the grid layout after the expanded row has been shrunk.
250    
251     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
252     Windows.
253    
254     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
255     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
256 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
257 tony 35
258     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
259 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
260 tony 35
261     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
262     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
263 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
264 tony 35
265     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
266     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
267     implies no truncation.
268    
269     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
270    
271     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
272     (avoids "Not in Edit Mode" error).
273    
274     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
275    
276     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
277     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
278    
279     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
280    
281     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
282    
283     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
284    
285     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
286    
287 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
288 tony 31
289     1. OnCloseUp Event Handler added to TDBLookupProperties
290    
291     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
292     problem with row size when exception is called.
293    
294     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
295    
296     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
297     in a TCustomComboBox and ignores return key if in a TCustomMemo
298    
299     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
300     keyed in i.e. when autocomplete not performed
301    
302 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
303     console mode applications with all LCL required functions (builtin dialogs and
304     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
305     not included in your project, IBX should compile and link with a console mode program.
306     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
307     console mode application or the IDE will automatically assume that your
308     application is GUI based. Instead, you should include the ibexpressconsolemode package.
309 tony 31
310     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
311     to use the built in dialogs and cursor management. IBDialogs is
312 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
313 tony 31 This should be the case for all projects created through the IDE. This is why
314     you do not want to add the ibexpress package to console mode applications. The
315     ibexpressconsolemode package has been created to allow console mode programs
316     to avoid adding LCL dependencies when using IBX, while still having the
317     unit search paths set up correctly.
318    
319 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
320     each project's source file (*.lpr).
321    
322 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
323     exists, you have to first open the package in the IDE and then close it. This
324     adds it to the most recently accessed packages list. To make it permanently
325     available, add the package name to lazarus' staticpackages.inc file.
326    
327 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
328 tony 31
329     7. SQL Parser can now accept quoted strings that include new lines
330    
331     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
332     of text on start of edit. This is particularly useful when tabbing to a
333     column and then inserting text.
334    
335     9. New Examples provided for IB Services and ISQLMonitor.
336    
337     10. Fix error when writing to blob streams that recorded only the last buffer
338     write in the blob stream. In most cases, this did not cause a problem as the
339     IB Blob Stream is written in a single write. However, with the TDBImage, write
340     of a graphic type prefix was lost which caused a problem when the image could
341     not be automatically recognised.
342    
343     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
344 tony 33 already open" errors due to random numbers used for the cursor name being identical.
345 tony 31
346     12. IBTable: corrected error that could result in an "Index out of bounds" error
347     when opening the table and the Primary Key is the last or only column in the
348     table. Thanks to Rick Hoover for the fix.
349    
350 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
351     of "UTF-8", and update list of available database character sets. Existing
352     users should check the current lc_ctype setting in their applications.
353 tony 29
354 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
355    
356 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
357     empty Params property.
358    
359     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
360     Link now set up in Loaded method - avoids occasional failure to apply
361     SQL markup on initial open.
362    
363     3. "Employees" example performance improvements when scrolling.
364    
365     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
366     TFrame. Force recaching of selected frame to avoid GTK race (results in a
367     random image cached).
368    
369     5. DBControlGrid: Should now react to changes in panel height at run time.
370    
371     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
372     even when further rows exist.
373    
374     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
375     always be derived from panel height and setting this property can cause confusion.
376     Note for existing projects: to avoid a missing property error at run time,
377     each form using the DBControlGrid must be opened, updated and saved in the IDE
378     in order to remove the property value from the lfm.
379    
380    
381 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
382 tony 27
383     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
384     call Prepare before setting parameter values.
385    
386     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
387    
388     3. Code tidyup and more robust handling of dsql information result vector.
389    
390     4. Support for centralised handling of transaction status changes. TIBTransaction
391     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
392     and "AfterExecQuery". The first three are called after the same event is called
393     for an IBCustomDataSet descendent using the Transaction. The fourth is called
394     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
395     enable monitoring of transaction status changes for a given transaction to be
396     handled in a single place. For example, when a change to the dataset occurs
397     an indicator can be set that shows the user that in order to save changes,
398     the transaction should be committed. Rather than doing this per dataset, this
399     can now be done per transaction.
400    
401     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
402     the dataset is scrolled. However, any changes to the current row are, by default,
403     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
404     have a new property "DataSetCloseAction" that adds automatic posting of changes
405     on dataset close. If this property is set to dcDiscardChanges (default) then the
406     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
407     then IBX will attempt to post any unsaved changes before the dataset is closed
408     (and after the BeforeClose event handler is called). The exception is when the
409     dataset is being closed as a result of a transaction rollback. In this case,
410     no action is taken and any unsaved changes are discarded. This avoids both
411     unnecessary overhead and the risk that a validation error may occur in the Post
412     raising an exception and thereby preventing a rollback.
413    
414     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
415     In earlier versions, the Display Width was set to the maximum byte width rather than the character
416     width. Display Widths are now corrected by dividing by the max byte width per character.
417     For UTF8 character sets, the byte width is four and hence the Display Width will be
418     the byte width divided by 4. The byte width of each character set is determined
419     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
420     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
421    
422     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
423    
424     8. IBLookupComboEditBox: List should now always be restored to full list when the
425     control loses focus. Default Key press default interval reduced to 200ms.
426    
427     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
428     when dataset rows are less than visible rows.
429    
430     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
431     does not exist or DataSet is empty. More responsive on dataset open. New event
432     OnRestorePosition. Column sort disabled if no header row.
433    
434     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
435     while dataset state is dsInsert. Avoids posting errors.
436    
437     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
438     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
439    
440     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
441    
442     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
443     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
444     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
445     always "posts" the current record regardless or whether or not it may be more appropriate
446     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
447     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
448     as the first action of the "Post" method and allows the handler to convert the Post
449     into a Cancel if that is the appropriate action on moving to a different row. This is
450     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
451     raised here, but it may still be more appropriate to validate a post and signal
452     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
453    
454     15. On Unix derived systems, the Firebird library name can now be given as a colon
455     separated list. Each library name on the list is tried in turn, in left to right
456     order with the first found being used as the firebird library. By default, on Linux,
457     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
458     overidden by the FBLIB environment variable or the OnGetLibraryName function.
459    
460     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
461     then it will still attempt to access the database via the Firebird Server and will
462     require a username and password. If only the pathname is given, then the username
463     and password should be omitted and the unix file permissions are used to grant
464     access.

468     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
469     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
470     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
471 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
472 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
473    
474     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
475 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
476 tony 23 takes place during database access. This may be useful when there are performance issues with
477     the change of cursor. Setting the property to false suppresses the change of cursor.
478    
479     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
480     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
481     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
482     making all changes permanent immediately rather than when the transaction is explicitly
483     committed.
484    
485 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
486 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

494     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
495     This is typically used during an "OnBeforeOpen" event handler to manipulate the
496     "Where" and "Having" clauses to implement user specified filters of arbitrary
497     complexity.
498    
499     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
500     three new data aware controls dependent on IBX and which make use of the SQL Parser.
501     These are:
502    
503     - TIBLookupComboEditBox
504     - TIBDynamicGrid
505     - TIBTreeview
506    
507     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
508     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
509     to revise the available list and restrict it to items that are prefixed by the
510 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
511 tony 21 newly typed entry to be added to the list dataset and included in the available
512     list items.
513    
514     TIBDynamicGrid is a TDBGrid descendent that provides for:
515     - automatic resizing of selected columns to fill the available row length
516     - automatic positioning and sizing of a "totals" control, typically at the
517     column footer, on a per column basis.
518     - DataSet resorting on header row click, sorting the dataset by the selected column.
519     A second click on the same header cell reversed the sort order.
520     - Support for a "Panel Editor". That is on clicking the indicator column, the row
521     is automatically expanded and a panel superimposed on it. The panel can have any
522     number of child controls, typically data aware controls with the same datasource
523     as the grid allowing for editing of additional fields and more complex editors.
524     - Reselection of the same row following resorting.
525     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
526     Its properties are specified on a per column basis and allows for one or more
527     columns to have their values selected from a list provided by a dataset.
528     Autocomplete and autoinsert are also available. The existing picklist editor
529     is unaffected by the extension.
530    
531     TIBTreeView is a data aware TCustomTreeView.
532    
533     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
534     zero scale will no longer return an error. An Int64 will be returned instead.
535    
536     4. TIBTransaction now has events for Before and After Transaction End and a new function
537     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
538    
539     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
540     repeated multiple times.
541    
542     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
543     check used to get in the way of using Stored Procedures, and "Update or Insert"
544     statements.
545    
546     7. Insert, Modify and Delete property Editors now support Query Generation from
547     Stored Procedures.
548    
549     8. Three new examples illustrate the use of the new IB Controls
550

554     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
555     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
556     Gabor Boros for reporting this problem and for testing the improvements).
557    
558     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
559     See readme.field+param.names in the doc folder.
560    
561     3. IBX SQL Editors will now automatically add double quotes around column names when the database
562     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
563    
564     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
565    
566     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
567     actions.
568    
569     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
570     thanks to Yuriy Kopnin for pointing this out).
571    
572     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
573    
574     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
575     for both fields and parameter setting.
576    
577     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
578     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
579    
580     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
581     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
582    
583     11. TIBTable now has a property editor for "MasterFields"
584    
585     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
586     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
587    
588     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
589     of settings is unrecognised. Selecting this radio button has no effect on the settings.

598     1. In a TIBCustomDataset descendent, a generator now only sets the value when
599     it is null. This allows for alternative user defined setting of the generator
600    
601     Many thanks to Julio Jiménez for this fix
602    
603     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
604     and suggests that the user may have forgotten to install it.

608     1. Conditional compilation used to limit registration of TIntegerField to
609     Lazarus versions less than 1.1
610    
611     2. When a database connection is created, character set is now by default set
612     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
613     1250 to 1254.

623     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
624     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
625    
626     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
627     package is changed to do this (which it should do).
628    
629     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
630    
631     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
632    
633     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
634    
635     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
636    
637     4. Property editors should now correctly resize.
638    
639     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
640     (restored original functionality)
641    
642     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
643     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
