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 tony 43 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 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
70 tony 41
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 tony 39 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 tony 37 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 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
187    
188 tony 37 1.3.2 was never formally released and only made available as beta copies.
189    
190 tony 35 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 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
212 tony 35
213     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
214 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
215 tony 35
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 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
219 tony 35
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 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
243 tony 31
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 tony 33 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 tony 31
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 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
268 tony 31 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 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
275     each project's source file (*.lpr).
276    
277 tony 31 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 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
283 tony 31
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 tony 33 already open" errors due to random numbers used for the cursor name being identical.
300 tony 31
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 tony 33 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 tony 29
309 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
310    
311 tony 29 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 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
337 tony 27
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.

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 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
427 tony 23 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 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
431 tony 23 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 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
441 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

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 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
466 tony 21 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

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.

552    
553     1. In a TIBCustomDataset descendent, a generator now only sets the value when
554     it is null. This allows for alternative user defined setting of the generator
555    
556     Many thanks to Julio Jiménez for this fix
557    
558     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
559     and suggests that the user may have forgotten to install it.
560

562    
563     1. Conditional compilation used to limit registration of TIntegerField to
564     Lazarus versions less than 1.1
565    
566     2. When a database connection is created, character set is now by default set
567     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
568     1250 to 1254.

578     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
579     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
580    
581     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
582     package is changed to do this (which it should do).
583    
584     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
585    
586     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
587    
588     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
589    
590     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
591    
592     4. Property editors should now correctly resize.
593    
594     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
595     (restored original functionality)
596    
597     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
598     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
