|
| 3 |
> |
1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf |
| 4 |
> |
changes. |
| 5 |
> |
|
| 6 |
> |
2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString. |
| 7 |
> |
Bug could result in truncated multi-byte character set values. |
| 8 |
> |
|
| 9 |
> |
3. Changes consequential on moving fbintf character set utility functions from |
| 10 |
> |
IFirebirdAPI to IAttachment. |
| 11 |
> |
|
| 12 |
> |
4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true |
| 13 |
> |
|
| 14 |
> |
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally |
| 15 |
> |
results in autocomplete ignoring prefix text. |
| 16 |
> |
|
| 17 |
> |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when |
| 18 |
> |
entering a new name into the text box. |
| 19 |
> |
|
| 20 |
> |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by |
| 21 |
> |
Firebird rather than recomputing it. |
| 22 |
> |
|
| 23 |
> |
8. Property Editor positioning tidy up: All IBX Property editors should now be |
| 24 |
> |
screen centre. Previously some were "poDesigned" which may be inappropriate |
| 25 |
> |
for multi monitor desktops. |
| 26 |
> |
|
| 27 |
> |
10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. |
| 28 |
> |
|
| 29 |
> |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending |
| 30 |
> |
a transaction and always reset the object. |
| 31 |
> |
|
| 32 |
> |
12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows. |
| 33 |
> |
|
| 34 |
> |
13. TIBXScript: Allow for override of database filename in Create Database statements. |
| 35 |
> |
|
| 36 |
> |
14. IBLocaldb: Support initialisation of the database from an SQL script in addition |
| 37 |
> |
to a gbak format archive. |
| 38 |
> |
|
| 39 |
> |
15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised. |
| 40 |
> |
|
| 41 |
> |
16. IBLocaldb: Drop database if error creating an empty database. |
| 42 |
> |
|
| 43 |
> |
17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset |
| 44 |
> |
unless selected node not in current dataset. |
| 45 |
> |
|
| 46 |
> |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) |
| 47 |
> |
to TIBCustomService, and IBlocalDB code tidy up. |
| 48 |
> |
|
| 49 |
> |
19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable |
| 50 |
> |
behaviour due to uninitialised variable. |
| 51 |
> |
|
| 52 |
> |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from |
| 53 |
> |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. |
| 54 |
> |
|
| 55 |
> |
21. IBSQL: When Database changed ensure that all resources are freed. |
| 56 |
> |
|
| 57 |
> |
22. IBCustomDataset: When database changed ensure that queries an unprepared. |
| 58 |
> |
|
| 59 |
> |
23. SQL Property Editors now use SynEdit with SQL Highlighter. |
| 60 |
> |
|
| 61 |
> |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). |
| 62 |
> |
|
| 63 |
> |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to |
| 64 |
> |
TVariantArray. Seems to avoid memory corruption in Windows (probably a |
| 65 |
> |
workaround for a problem in fpc 3.0.4 win64). |
| 66 |
> |
|
| 67 |
> |
26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open. |
| 68 |
> |
|
| 69 |
> |
IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000 |
| 70 |
> |
|
| 71 |
> |
1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to |
| 72 |
> |
include remote system name. |
| 73 |
> |
|
| 74 |
> |
2. TIBExtract: No longer include comment header and COMMIT statement for empty |
| 75 |
> |
tables when data included in output. |
| 76 |
> |
|
| 77 |
> |
3. Profiling: IBSQL now has conditional compilation flags to enable query performance |
| 78 |
> |
and timing information to be written to stdout. This may be used to locate |
| 79 |
> |
performance bottlenecks. |
| 80 |
> |
|
| 81 |
> |
4. SQLParser: only call "OnChanging" event handler when value is different. |
| 82 |
> |
|
| 83 |
> |
5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit |
| 84 |
> |
|
| 85 |
> |
6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures |
| 86 |
> |
that BindFields is called when the query is next activated. Avoids FieldName |
| 87 |
> |
not found error. |
| 88 |
> |
|
| 89 |
> |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general |
| 90 |
> |
purpose and allows the programmer to define any action they want for Update, Insert |
| 91 |
> |
or Delete. This may be complex SQL (similar to a Trigger), application specific |
| 92 |
> |
filtering of updates, or use of statements such as Grant or Revoke instead of |
| 93 |
> |
normal DML. See User Manual for more information. |
| 94 |

|
| 97 |
> |
1. TIBEvents: Fix uninitialised variable that could result in lost events. |
| 98 |
> |
|
| 99 |
> |
2. TIBExtract: Added support for FB3 "USAGE" privilege. |
| 100 |
> |
|
| 101 |
> |
3. TIBExtract: data formatted as Charset set "octets" is now output using |
| 102 |
> |
hexadecimal notation. |
| 103 |
> |
|
| 104 |
> |
4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements |
| 105 |
> |
using a simple XML format. |
| 106 |
> |
|
| 107 |
> |
5. TIBExtract: extract of individual Triggers and Stored Procedures can now include |
| 108 |
> |
grants to these objects. |
| 109 |
> |
|
| 110 |
> |
6. TIBExtract: Stored Procedures and Views output in dependency order to avoid |
| 111 |
> |
dependency problems restoring complex databases. |
| 112 |
> |
|
| 113 |
> |
7. TIBXScript: This component has been restructured to allow for the processing of |
| 114 |
> |
embedded XML in INSERT statements and to support interactive sources in addition |
| 115 |
> |
to non-interactive data sources such as files. |
| 116 |
> |
|
| 117 |
> |
8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported. |
| 118 |
> |
|
| 119 |
> |
9. TIBXScript: ISQL compatiable Set statements are now supported: |
| 120 |
> |
SET SQL DIALECT |
| 121 |
> |
SET TERM |
| 122 |
> |
SET AUTODDL |
| 123 |
> |
SET BAIL |
| 124 |
> |
SET ECHO |
| 125 |
> |
SET COUNT |
| 126 |
> |
SET STATS |
| 127 |
> |
SET NAMES <character set> |
| 128 |
> |
|
| 129 |
> |
10. IBVersion unit added to hold current IBX Version Number information. |
| 130 |
> |
|
| 131 |
> |
11. TIBExtract: Use character rather than byte length for VarChar procedure arguments., |
| 132 |
> |
and domain definitions. |
| 133 |
> |
|
| 134 |
> |
12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers |
| 135 |
> |
fully supported. |
| 136 |
> |
|
| 137 |
> |
13. TIBExtract: when a database dump includes data, the generator values are now also set. |
| 138 |
> |
|
| 139 |
> |
14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later. |

IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000 |
| 142 |

|
| 143 |
> |
See also doc/IBX4LazarusGuide.pdf for important information on |
| 144 |
> |
upgrading to IBX2. |
| 145 |
> |
|
| 146 |
> |
1. Size property of TIBStringField is now the width in characters of the field |
| 147 |
> |
and not the byte length. This applies only to multi-byte character sets such |
| 148 |
> |
as UTF8. The original approach aligned with TStringField. However, the TStringField |
| 149 |
> |
code is not recognised as a bug and hence this change to align the behaviour. |
| 150 |
> |
The TStringField change is expected in fpc 3.2.0. |
| 151 |
> |
|
| 152 |
> |
2. A new property AutoFieldSize: boolean has been added to TIBStringField. When |
| 153 |
> |
true (default) then Size property value saved in the lfm is ignored. Size is |
| 154 |
> |
always set from the dynamic information read from the database. It is unclear |
| 155 |
> |
why anyone would want to override this and set Size to false. |
| 156 |
> |
|
| 157 |
> |
3. ibxscript: should now handle correctly a Case..End statement within a procedure |
| 158 |
> |
block. |
| 159 |
> |
|
| 160 |
> |
4. IBDatabase: new property - CreateIfNotExists. If true and database does not |
| 161 |
> |
exist when an attempt is made to connect to it (run time only) then an attempt |
| 162 |
> |
is made to create the database. |
| 163 |
> |
|
| 164 |
> |
5. IBDatabase: new event - OnCreateDatabase. This event is called after a database |
| 165 |
> |
has been successfully created as a result of a call to CreateDatabase or when |
| 166 |
> |
creating a database after it was found not to exist. |
| 167 |
> |
|
| 168 |
> |
6. DBControlGrid: a race condition could result in the wrong row image being |
| 169 |
> |
written to the cache. This has been avoided by a trip round the message |
| 170 |
> |
loop before rendering the row image. |
| 171 |
> |
|
| 172 |
> |
7. DBControlGrid: It is strongly recommended not to open the source DataSet for |
| 173 |
> |
a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is |
| 174 |
> |
known to risk corrupt rendering of row images when the control is first |
| 175 |
> |
displayed. If necessary use "Application.QueueAsyncCall" to delay opening |
| 176 |
> |
of the dataset (see DBControlGrid examples) until the Form's Window has been created. |
| 177 |
> |
|
| 178 |
> |
8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with |
| 179 |
> |
a TDateEdit control located on an editor panel. |
| 180 |
> |
|
| 181 |
> |
9. TIBExtract: brought up-to-date plus many bug fixes. |
| 182 |
> |
|
| 183 |
> |
10. DBControlGrid: Removed memory leak when updating rows. |
| 184 |
> |
|
| 185 |
> |
11. TIBCMLocalDBSupport: fixed invalid free on upgrade. |
| 186 |
> |

| 188 |
> |
|
| 189 |
> |
1. IBCustomDataset: When calling SetCodePage, no longer request transliteration |
| 190 |
> |
when target codepage is CP_NONE. This is a workaround for |
| 191 |
> |
http://bugs.freepascal.org/view.php?id=30622. |
| 192 |
> |
|
| 193 |
> |
2. DBLog option removed from TIBStatisticalService - not supported by server |
| 194 |
> |
since Firebird 1.5. |
| 195 |
> |
|
| 196 |
> |
3. ibxscript: An error is no longer generated for "on commit preserve rows" or |
| 197 |
> |
similar. |
| 198 |
> |
|
| 199 |
> |
4. IBCodePage: updated mapping between codepages and character id. |
| 200 |
> |
|
| 201 |
> |
5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in |
| 202 |
> |
Firebird. Character sets with a char width of two are not UTF16. |
| 203 |
> |
|
| 204 |
> |
6. Strings received from the database are now always transliterated into UTF8 |
| 205 |
> |
regardless of the database character set or connection character set. This |
| 206 |
> |
is for compatibility with the LCL. |
| 207 |
> |
|
| 208 |

|
| 210 |
> |
1. IBBlob: Defer reading of blob until read method called. This avoids having to |
| 211 |
> |
read in an entire blob just to get the size of the blob. General performance |
| 212 |
> |
improvement when opening datasets containing blobs. |
| 213 |
> |
|
| 214 |
> |
2. Clearing a Blob now sets the corresponding field's modified flag. |
| 215 |
> |
|
| 216 |
> |
3. IBLookupCombo: When not performing auto-complete, original query sort order |
| 217 |
> |
is now used. |
| 218 |
> |
|
| 219 |
> |
4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically |
| 220 |
> |
determined. |
| 221 |
> |
|
| 222 |
> |
5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened. |
| 223 |
> |
|
| 224 |
> |
6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post |
| 225 |
> |
lazarus 1.6.0 |
| 226 |
> |
|
| 227 |
> |
7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages" |
| 228 |
> |
compilation error. |
| 229 |
> |
|
| 230 |
> |

|
| 232 |
> |
1. No character set specified for connection: when a text blob is retrieved, the |
| 233 |
> |
character set is determined by looking up the native character set using then |
| 234 |
> |
Firebird API. Otherwise a text mode blob is assumed to have the same character |
| 235 |
> |
set as the connection. |
| 236 |
> |
|
| 237 |
> |
2. TIBGUIInterface: this is an internal interface. Minor type changes to allow |
| 238 |
> |
for Login Dialog returing a change to the database path. |
| 239 |
> |
|
| 240 |
> |
3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name |
| 241 |
> |
to be changed from that given in the TIBDatabase/TIBServer component and for the |
| 242 |
> |
entered value to be saved on a project specific basis (design time only). |
| 243 |
> |
|
| 244 |
> |
4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the |
| 245 |
> |
column fieldname. If they are the same then it is acts as a look up for the KeyValue |
| 246 |
> |
Otherwise, it sets the column text to the selected ListField Value. |
| 247 |
> |
|
| 248 |
> |
5. IBDynamicGrid: Only visible columns are now taken into account When recalculating |
| 249 |
> |
column width. |
| 250 |
> |
|
| 251 |
> |
6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given |
| 252 |
> |
and a case insensitive search is requested. |
| 253 |
> |
|
| 254 |
> |
7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls |
| 255 |
> |
or column ListSource. |
| 256 |
> |
|
| 257 |
> |
8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an |
| 258 |
> |
unprepare) when closing and the text has not changed. |
| 259 |
> |
|
| 260 |
> |
9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer. |
| 261 |
> |
Less likely to cause a cursor re-use error on Windows. |
| 262 |
> |
|
| 263 |
> |
10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin. |
| 264 |
> |
Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0. |
| 265 |
> |
|
| 266 |
> |
11. TIBTreeView: Guard against nil destination on record changed |
| 267 |
> |
|
| 268 |
> |
12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a |
| 269 |
> |
string type with the code page set to reflect the returned field encoding after |
| 270 |
> |
Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for |
| 271 |
> |
earlier versions. |
| 272 |
> |
|
| 273 |
> |
13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString |
| 274 |
> |
will now result in transliteration to the code page specified for the Firebird driver |
| 275 |
> |
if the assigned string has a different code page. FPC 3.0.0 onwards only. |
| 276 |
> |
|
| 277 |
> |
14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter |
| 278 |
> |
is ignored and the lc_ctype value, when the database is opened, is set to align with |
| 279 |
> |
the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure |
| 280 |
> |
platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC |
| 281 |
> |
3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when |
| 282 |
> |
the GETACP is used to determine the Windows code page. |
| 283 |
> |
|
| 284 |
> |
15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set |
| 285 |
> |
name used as the lc_ctype when the database was opened. Only valid while the |
| 286 |
> |
Database is connected. |
| 287 |
> |
|
| 288 |
> |
16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage |
| 289 |
> |
id that corresponds to the DefaultCharSetName. |
| 290 |
> |

1. Unix: If Firebird Embedded Server shared object is loaded and a local database |
| 294 |
> |
path is given and database attach fails due to access permission issues on the |
| 295 |
> |
temp directory or security database, then the attach is retried with "localhost:" |
| 296 |
> |
prefixing the databasename. This should avoid problems when the database has to |
| 297 |
> |
be accessed by a local (e.g. classic) server and libfbembed is used. |
| 298 |
> |
|
| 299 |
> |
2. Windows: revised search order for Firebird DLL: |
| 300 |
> |
i. The Firebird Embedded Server in the application Directory. |
| 301 |
> |
ii. If the FIREBIRD environment variable is set then the directory this |
| 302 |
> |
points to is searched for the FB Client DLL and then then underlying |
| 303 |
> |
"bin" directory. |
| 304 |
> |
iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances |
| 305 |
> |
is used to locate the Firebird installation directory and the underlying |
| 306 |
> |
"bin" directory is searched for the FB Client DLL. |
| 307 |
> |
iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x |
| 308 |
> |
are searched for the FB Client DLL. |
| 309 |
> |
v. The PATH Environment variable is used to search for the FB Client DLL. |
| 310 |
> |
vi. Finally the PATH Environment variable is used to search for IBASE.DLL. |
| 311 |
> |
|
| 312 |
> |
3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine. |
| 313 |
> |
See doc/readme.scriptengine and example applications. |
| 314 |
> |
|
| 315 |
> |
4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to |
| 316 |
> |
simplify the use of the embedded firebird server on both Linux and Windows platforms. |
| 317 |
> |
See dpc/readme.localdatabase and example applications. |

IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000 |
| 326 |

|
| 327 |
> |
1.3.2 was never formally released and only made available as beta copies. |
| 328 |
> |
|
| 329 |
> |
1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo |
| 330 |
> |
|
| 331 |
> |
2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column |
| 332 |
> |
|
| 333 |
> |
3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early |
| 334 |
> |
|
| 335 |
> |
4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset |
| 336 |
> |
i.e. when it is a calculated field |
| 337 |
> |
|
| 338 |
> |
5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid. |
| 339 |
> |
This problem was due to a race condition between recalculating row heights and |
| 340 |
> |
determining which row was selected by the mouse click. The row height calculation |
| 341 |
> |
is now deferred by an extra trip round the message loop allowing the row to |
| 342 |
> |
be always calculated on the current grid layout rather than risking it being |
| 343 |
> |
calculated on the grid layout after the expanded row has been shrunk. |
| 344 |
> |
|
| 345 |
> |
6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on |
| 346 |
> |
Windows. |
| 347 |
> |
|
| 348 |
> |
7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer; |
| 349 |
> |
These properties allow the (Firebird) character set name for the field and the max number of bytes per character |
| 350 |
> |
to be determined at runtime. See doc/readme.charactersets.html. |
| 351 |
> |
|
| 352 |
> |
8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from |
| 353 |
> |
TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html. |
| 354 |
> |
|
| 355 |
> |
9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from |
| 356 |
> |
TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of |
| 357 |
> |
1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html. |
| 358 |
> |
|
| 359 |
> |
Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated |
| 360 |
> |
from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero |
| 361 |
> |
implies no truncation. |
| 362 |
> |
|
| 363 |
> |
10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active. |
| 364 |
> |
|
| 365 |
> |
11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state |
| 366 |
> |
(avoids "Not in Edit Mode" error). |
| 367 |
> |
|
| 368 |
> |
12. IBDynamicGrid: Correctly resize grid when one column width plus indicator. |
| 369 |
> |
|
| 370 |
> |
13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling |
| 371 |
> |
DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control. |
| 372 |
> |
|
| 373 |
> |
14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent. |
| 374 |
> |
|
| 375 |
> |
15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls |
| 376 |
> |
|
| 377 |
> |
16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked. |
| 378 |
> |
|
| 379 |
> |
17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened. |

for further guidence. DO NOT add the ibexpress package to a console mode |

application or the IDE will automatically assume that you application is |

GUI based. Instead, you should include the ibexpressconsolemode package. |

|
IMPORTANT NOTE: IBDialogs must be included in GUI applications in order |
| 405 |
|
to use the built in dialogs and cursor management. IBDialogs is |
| 406 |
< |
included by default if "ibexpress" is in your project source "uses" clause. |
| 406 |
> |
included by default if "ibexpress" is in your project source's "uses" clause. |
| 407 |
|
This should be the case for all projects created through the IDE. This is why |
| 408 |
|
you do not want to add the ibexpress package to console mode applications. The |
| 409 |
|
ibexpressconsolemode package has been created to allow console mode programs |
| 410 |
|
to avoid adding LCL dependencies when using IBX, while still having the |
| 411 |
|
unit search paths set up correctly. |
| 412 |
|
|
| 413 |
+ |
Existing users should check to ensure that the "ibexpress" unit is included in |
| 414 |
+ |
each project's source file (*.lpr). |
| 415 |
+ |
|
| 416 |
|
You may find that in order for the IDE to recognise that ibexpressconsolemode |
| 417 |
|
exists, you have to first open the package in the IDE and then close it. This |
| 418 |
|
adds it to the most recently accessed packages list. To make it permanently |
| 419 |
|
available, add the package name to lazarus' staticpackages.inc file. |
| 420 |
|
|
| 421 |
< |
Under Windows, the TISQLMonitor OnSQL Event Handler may require a new call to |
| 39 |
< |
Application.ProcessMessages in order to display an event journal correctly. See |
| 40 |
< |
example. This was previously called by TISQLMonitor itself but removed to avoid |
| 41 |
< |
a GUI dependency. |
| 42 |
< |
|
| 43 |

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

7. SQL Parser can now accept quoted strings that include new lines |
| 424 |
|
|
| 435 |
|
not be automatically recognised. |
| 436 |
|
|
| 437 |

11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor |
| 438 |
< |
already open" errors due to random numbers being identical. |

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

|
12. IBTable: corrected error that could result in an "Index out of bounds" error |
| 441 |
|
when opening the table and the Primary Key is the last or only column in the |
| 442 |
|
table. Thanks to Rick Hoover for the fix. |

13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead |
| 445 |

1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike |
| 563 |
|
rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid |
| 579 |
|
4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still |
| 580 |
|
using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature. |
