|

> |
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 |

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 |

115 |
> |
|
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 |

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 |
> |

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 |
> |
|

IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000 |
232 |
> |
|
233 |
> |
1.3.2 was never formally released and only made available as beta copies. |
234 |
> |
|
235 |
> |
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 |
> |
to be determined at runtime. See doc/readme.charactersets.html. |
257 |
> |
|
258 |
> |
8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from |
259 |
> |
TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html. |
260 |
> |
|
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 |
> |
1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html. |
264 |
> |
|
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. |

|
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 |
> |
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 |
> |
|
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 |
> |
included by default if "ibexpress" is in your project source's "uses" clause. |
313 |
> |
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 |
> |
Existing users should check to ensure that the "ibexpress" unit is included in |
320 |
> |
each project's source file (*.lpr). |
321 |
> |
|

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. |

Thanks to Julio Jiménez for suggesting support of console mode. |

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 |
> |
already open" errors due to random numbers used for the cursor name being identical. |
345 |
> |
|
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 |

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. |

|
356 |
> |
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. |

IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100 |
382 |
> |
|
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 |
> |
corresponds to a row of the linked DataSource. Any data aware control on the |
472 |
> |
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 |
> |
When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change |
476 |
> |
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 |
> |
4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still |
486 |
> |
using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature. |

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 |
> |
typed text (either case sensitive or case insensitive). Autoinsert allows a |
511 |
> |
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 |

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. |
