1. Add try-..except check when initially loading library in IDE. This should |
| 4 |
> |
ensure that IDE continues to load even when a failure occurs in IBX load |
| 5 |
> |
library. |
| 6 |
> |
|
| 7 |
> |
2. IBXScript: now recognises a CASE...END block within a stored procedure and |
| 8 |
> |
hence will correctly detect end of the outer containing block when the block |
| 9 |
> |
contains a SELECT ... CASE ... END construct. |
| 10 |
> |
|
| 11 |
> |
3. IBExtract: some further tidying up to remove extraneous white space. |
| 12 |
> |
|
| 13 |
> |
4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time |
| 14 |
> |
errors when extra elements are added to DB.TFieldType. |
| 15 |
> |
|
| 16 |
> |
5. IBUpdate: updated to reflect changes to ISQLParam. |
| 17 |
> |
|
| 18 |
> |
6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string. |
| 19 |
> |
|
| 20 |
> |
7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement. |
| 21 |
> |
|
| 22 |
> |
8. IBSQL: Support for scrollable cursors added (note: local databases only) |

1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the |
| 27 |
> |
exception of those defined to be one byte wide e.g. DBImplementationNo. |
| 28 |
> |
|
| 29 |
> |
2. TIBSQL: Batch Update/Insert support added. |
| 30 |
> |
|
| 31 |
> |
3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property |
| 32 |
> |
is no longer automatically converted to upper case when it is syntactically a |
| 33 |
> |
SQL Identifier. This is to support the use of stored procedures defined e.g. |
| 34 |
> |
as CREATE PROCEDURE "iCASE". |
| 35 |
> |
|
| 36 |
> |
There could be a backwards compatibility issue when the StoredProcName was entered |
| 37 |
> |
manually at design time. That is not selected from the drop down list. If the |
| 38 |
> |
StoredProcName is entered in mixed case and the procedure was declared e.g. as |
| 39 |
> |
CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should |
| 40 |
> |
ensure that the value of the StoredProcName is all upper case, unless it was |
| 41 |
> |
declared under dialect 3 and explicitly as mixed case (i.e. delimited by double |
| 42 |
> |
quotes). |
| 43 |
> |
|
| 44 |
> |
Note that when a stored procedure name was declared delimited in double quotes, |
| 45 |
> |
as in the first example above, the value of the StoredProcName property must not |
| 46 |
> |
include the delimiters (double quotes). |
| 47 |
> |
|
| 48 |
> |
4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in |
| 49 |
> |
upgrade.conf was not found. This replaces silently ignoring the problem. |
| 50 |
> |
|
| 51 |
> |
5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to |
| 52 |
> |
'Version.%.3d' and is used to generate the section header names (for a given |
| 53 |
> |
version no.) in the upgrade.conf file. |
| 54 |

|
| 62 |
> |
1. Firebird 4 support added. |
| 63 |
> |
|
| 64 |
> |
2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and |
| 65 |
> |
extended precision NUMERIC fields are supported. |
| 66 |
> |
|
| 67 |
> |
3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields. |
| 68 |
> |
|
| 69 |
> |
4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE |
| 70 |
> |
and TIME WITH TIME ZONE fields. These inherit from TDateTimeField. |
| 71 |
> |
|
| 72 |
> |
5. IBExtract now supports FB4 enhancements: |
| 73 |
> |
- new data types as above |
| 74 |
> |
- Identity column extensions |
| 75 |
> |
- Default user role |
| 76 |
> |
- SQL Security clause for Database, Tables, Procedures, Functions and Triggers |
| 77 |
> |
- Internal Functions |
| 78 |
> |
|
| 79 |
> |
6. IBExtract: new event: OnExtractLines. |
| 80 |
> |
|
| 81 |
> |
7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145 |
| 82 |
> |
|
| 83 |
> |
8. IBXServices: Server version no. parsing now allows any letter before major version number |
| 84 |
> |
and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1" |
| 85 |
> |
|
| 86 |
> |
9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default |
| 87 |
> |
format for rendering a time zone. |
| 88 |
> |
|
| 89 |
> |
10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date |
| 90 |
> |
to convert TIME WITH TIME ZONE data type values to and from GMT. |
| 91 |
> |
|
| 92 |
> |
11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to |
| 93 |
> |
IIBGUIInterface and IIBTimerInf respectively. |
| 94 |
> |
|
| 95 |
> |
12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames |
| 96 |
> |
now accessible as properties of TIBDatabase and TIBTransaction respectively. |
| 97 |
> |
|
| 98 |
> |
13. String Fields: when a fixed character with (CHAR) field is returned, it is now |
| 99 |
> |
truncated to its fixed character width rather than being right padded with |
| 100 |
> |
white space to the maximum data size. |
| 101 |
> |
|
| 102 |
> |
14. TIBTable.Empty table. In additional to deleting all records in the underlying |
| 103 |
> |
table, the internal buffers are now also flushed ensuring that the TIBTable is |
| 104 |
> |
also empty. |
| 105 |
> |
|
| 106 |
> |
15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset. |
| 107 |
> |
|
| 108 |
> |
16. TIBXControlService descendents: DatabaseName may now be set using a database |
| 109 |
> |
connect string. The database name is extracted from the connect string. |
| 110 |
> |
|
| 111 |
> |
17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel |
| 112 |
> |
|
| 113 |
> |
18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL. |
| 114 |
> |
|
| 115 |
> |
19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password |
| 116 |
> |
not being present as required. |
| 117 |
> |
|
| 118 |
> |
20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent |
| 119 |
> |
version that can be customised to work with other database drivers. |
| 120 |
> |
|
| 121 |
> |
21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids |
| 122 |
> |
unnecessary CR at end of line on Unix platforms. |
| 123 |
> |
|
| 124 |
> |
22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10 |
| 125 |
> |
seconds in order to reduce risk of message loss. |
| 126 |
> |
|
| 127 |
> |
23. ISQLMonitor: read and write count statistics now available via: |
| 128 |
> |
property TIBSQLMonitor.ReadCount; |
| 129 |
> |
IIBSQLMonitorHook.GetWriteCount: integer; |
| 130 |
> |
|
| 131 |
> |
24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC. |

| 134 |
> |
|
| 135 |
> |
1. TIBStringField: when a string value is read from a dataset buffer, if the |
| 136 |
> |
number of UTF8 characters exceeds the string size then string is truncated |
| 137 |
> |
to the maximum string size. This is usually a problem with fixed width columns |
| 138 |
> |
right padded with white space. |
| 139 |
> |
|
| 140 |
> |
2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset. |
| 141 |
> |
If SQLFiltered is set then when a dataset is opened, each line in the |
| 142 |
> |
SQLFilterParams property is assumed to be a SQL condition clause and |
| 143 |
> |
ANDed into the Where clause of the SQL Select statement provided as a |
| 144 |
> |
dataset property. Each such SQL condition thus acts as an additional filter |
| 145 |
> |
on the dataset. |
| 146 |
> |
|
| 147 |
> |
3. The Filtered property inherited from TDataset is no longer used for SQL (server |
| 148 |
> |
side filters). |
| 149 |
> |
|
| 150 |
> |
4. IBLookupComboEditBox: Selection should no longer reset to start of text when |
| 151 |
> |
text matches complete entry. |
| 152 |
> |
|
| 153 |
> |
5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail |
| 154 |
> |
dataset are active (avoids risk of access violation if master is inactive) |
| 155 |
> |
|
| 156 |
> |
6. TIBEvents: Registered property can now be set at design time even if database not open |
| 157 |
> |
|
| 158 |
> |
7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents. |
| 159 |
> |
This should prevent "spillover" of events between sessions. |
| 160 |
> |
|
| 161 |
> |
8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset. |
| 162 |
> |
This should ensure that the internal buffer is set up correctly and avoids |
| 163 |
> |
a duplicate initial row. |
| 164 |
> |
|
| 165 |
> |
9. TIBStringField: DataSize now given as byte size of string less trailing any zero character. |
| 166 |
> |
That is, the DataSize should be the field size * character set width. The |
| 167 |
> |
value returned by DataSize is now the same as the Dataset buffer size reserved |
| 168 |
> |
for the field. |
| 169 |
> |
|
| 170 |
> |
10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes. |
| 171 |
> |
|
| 172 |
> |
11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer |
| 173 |
> |
and vice-versa. This may result in an exception being raised (correctly) for |
| 174 |
> |
older programs when using dataset fields added to a form and the database has been |
| 175 |
> |
upgraded. For example, computed fields can change from 32-bit to 64-bit integers. |
| 176 |
> |
In such cases, the field needs to be deleted in the IDE fields editor and then |
| 177 |
> |
added back in. |
| 178 |
> |
|
| 179 |
> |
12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return |
| 180 |
> |
false if query contains only white space and not just empty. |
| 181 |
> |
|
| 182 |
> |
12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This |
| 183 |
> |
should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit |
| 184 |
> |
is cancelled. |
| 185 |
> |
|
| 186 |
> |
13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if |
| 187 |
> |
called on a null field. |
| 188 |
> |
|
| 189 |
> |
14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates |
| 190 |
> |
results in an empty dataTC86 Client side Filtered Dataset 1 X |
| 191 |
> |
set. |
| 192 |
> |
|
| 193 |
> |
15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when |
| 194 |
> |
a cached update is applied and an exception is raised. |
| 195 |
> |
|
| 196 |
> |
16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer. |
| 197 |
> |
|
| 198 |
> |
17. Console Mode Local Database support: backup/restore should now work correctly. |
| 199 |
> |
|
| 200 |
> |
18. Local Database Support: if an upgrade fails, a downgrade is now performed if |
| 201 |
> |
possible and an exception raised. |
| 202 |
> |
|
| 203 |
> |
19. MinimumVersionNo added to Local Database Support. Database will not open if |
| 204 |
> |
below this version no. and upgrade not possible. |
| 205 |

| 208 |
> |
1. TIBXDataSet and Generators: Generator Names that are not all upper case or |
| 209 |
> |
not SQL Identifiers are now supported. |
| 210 |
> |
|
| 211 |
> |
2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is |
| 212 |
> |
passed to the Firebird engine for execution. |
| 213 |
> |
|
| 214 |
> |
3. TIBDataSet: Unidirectional datasets now give an error message if an attempt |
| 215 |
> |
is made to scroll back. |
| 216 |
> |
|
| 217 |
> |
4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf |
| 218 |
> |
|
| 219 |
> |
5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now |
| 220 |
> |
only enclosed in double quotes in SQL dialect 3 and when it needs to be. |
| 221 |
> |
|
| 222 |
> |
6. TIBLookupComboEditBox: when the list source opens, the ListField name is now |
| 223 |
> |
validated. If no match is found in the list of field names and the database has |
| 224 |
> |
been opened in SQL Dialect 3, then the ListField Name is converted to upper case |
| 225 |
> |
if it then matches a field name. Otherwise, a Listfield not valid exception occurs. |
| 226 |
> |
|
| 227 |
> |
7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance |
| 228 |
> |
with fpc 3.2. |
| 229 |
> |
|
| 230 |

1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides" |
| 234 |
> |
and is used to override the default settings in the client side "firebird.conf" This |
| 235 |
> |
includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings". |
| 236 |
> |
Each line of the string list should be a setting in the same format as "firebird.conf". |
| 237 |
> |
For example "WireCompression = true" in order to request wire compression on the client side. |
| 238 |
> |
|
| 239 |
> |
Note: explicit settings in the client side "firebird.conf" appear to take precedence |
| 240 |
> |
over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings |
| 241 |
> |
also require a compatible setting in the server side "firebird.conf". For example |
| 242 |
> |
"WireCompression = true" must also be set in the server's "firebird.conf" for wire |
| 243 |
> |
compression to be used. |
| 244 |
> |
|
| 245 |
> |
Whether or not WireCompression or WireCrypt are in use can be checked using the information |
| 246 |
> |
returned with the Client/Server protocol version. See ibx/examples/dbadmin and |
| 247 |
> |
ibx/examples/dbinfo for examples of how to display this information. |
| 248 |
> |
|
| 249 |
> |
2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This |
| 250 |
> |
is a "convenience" property. If set the "WireCompression=true" is added to the |
| 251 |
> |
ConfigOverrides. If unchecked then this setting is removed. |
| 252 |
> |
|
| 253 |
> |
3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and |
| 254 |
> |
not "INT64". |
| 255 |
> |
|
| 256 |
> |
4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut |
| 257 |
> |
These are: |
| 258 |
> |
property TimestampFormat: string; |
| 259 |
> |
property DateFormat: string; |
| 260 |
> |
property TimeFormat: string; |
| 261 |
> |
|
| 262 |
> |
Respectively, these provide the date time format templates for SQL types: TIMESTAMP, |
| 263 |
> |
DATETIME and TIME. The format strings use the standard FPC date/time format |
| 264 |
> |
characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html). |
| 265 |
> |
|
| 266 |
> |
If any of the above properties are set to an empty string, then the locale default |
| 267 |
> |
is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the |
| 268 |
> |
locale default is extended by appending '.zzz' to include milliseconds. |
| 269 |
> |
|
| 270 |
> |
TIBCSVDataOut by default sets these properties to the empty string, while the other |
| 271 |
> |
two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively. |
| 272 |
> |
|
| 273 |
> |
5. New published property for TIBCSVDataOut: |
| 274 |
> |
property QuoteStrings: boolean (default true) |
| 275 |
> |
|
| 276 |
> |
If false then strings are unquoted, otherwise, the QuoteChar property value is |
| 277 |
> |
used to delimit each and every string in the output. |
| 278 |
> |
|
| 279 |
> |
6. New published properties for TIBCSVDataOut: |
| 280 |
> |
property FieldSeparator: string; |
| 281 |
> |
property HeaderSeparator: string; |
| 282 |
> |
|
| 283 |
> |
Respectively, these provide the separator character(s) used to separate fields |
| 284 |
> |
in data and header rows. Both default to ','. |
| 285 |
> |
|
| 286 |
> |
7. New published properties for TIBCSVDataOut and TIBBlockFormatOut: |
| 287 |
> |
TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object; |
| 288 |
> |
property OnFormatTextString; |
| 289 |
> |
|
| 290 |
> |
This event handler can be used to process text strings before they are included |
| 291 |
> |
in the output e.g. to replace unprintable characters with alternative strings. |
| 292 |
> |
This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT. |
| 293 |
> |
|
| 294 |
> |
8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name. |
| 295 |
> |
Uses "FindParam" if in order to find out if a parameter with a given name exists |
| 296 |
> |
and without raising and exception if it does not. |
| 297 |
> |
|
| 298 |
> |
9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure |
| 299 |
> |
consistency with SQL queries. |
| 300 |
> |
|
| 301 |
> |
10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery. |
| 302 |
> |
When true, SQL statement parameter names are parsed case sensitive. Note for |
| 303 |
> |
TIBDataSet only applies to Select query. |
| 304 |
> |
|
| 305 |
> |
11. IBEvents: removing a TIBEvent component from a form should no longer result in |
| 306 |
> |
an IDE exception. |
| 307 |
> |
|
| 308 |
> |
12. LocalDBSupport: initial database creation should now work correctly |
| 309 |
> |
when the schema source is an sql file. |
| 310 |
> |
|
| 311 |
> |
13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent" |
| 312 |
> |
when defined, this handler will be called by the internal TIBXScript during |
| 313 |
> |
initial database creation when the schema source is an sql file and may be used |
| 314 |
> |
to provide a visual indication of progress in console mode. |
| 315 |
> |
|
| 316 |
> |
14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set |
| 317 |
> |
to true while a new local database is being created and its schema populated. |
| 318 |
> |
Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions |
| 319 |
> |
when the database is disconnected/connected during the create DB procedure. |
| 320 |
> |
|
| 321 |
> |
15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement |
| 322 |
> |
are now always ignored and replaced by the user name and password provided as |
| 323 |
> |
the login parameters for the TIBDatabase referenced from the TIBXScript. The |
| 324 |
> |
IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is |
| 325 |
> |
completely ignored if this property is true. |
| 326 |
> |
|
| 327 |
> |
16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes |
| 328 |
> |
to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise |
| 329 |
> |
ImageIndex and SelectImageIndex values on AddNode. |
| 330 |
> |
|
| 331 |
> |
17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now |
| 332 |
> |
read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share |
| 333 |
> |
the same database connection. |
| 334 |
> |
|
| 335 |
> |
18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property. |
| 336 |
> |
if provided, this should be an conditional SQL expression suitable for |
| 337 |
> |
including in an SQL Select statement "where" clause. If non-empty and the |
| 338 |
> |
"Filtered" property is true then the SQL expression provided as the value of |
| 339 |
> |
the "Filter" property is "ANDed" with any existing condition statement |
| 340 |
> |
in the SQL statement's "Where" clause. |
| 341 |
> |
|
| 342 |
> |
If the "Filter" property is set at run time, the "Filtered" property is true |
| 343 |
> |
and the dataset is already open, then the dataset is closed and re-opened automatically. |
| 344 |
> |
|
| 345 |
> |
The "Filter" condition may include IBX style parameters. In which case, their |
| 346 |
> |
value must be set by the dataset's "OnBeforeOpen" event handler. |
| 347 |
> |
|
| 348 |
> |
This is a public property for TIBDataSet and TIBQuery query and intended for |
| 349 |
> |
use at run time. |
| 350 |
> |
|
| 351 |
> |
Note: The property is a published property of TIBTable. The TIBTable functionality |
| 352 |
> |
is unaffected by this change. |

1. Remove need to check for IsMultiThread by providing access to GUI timers via |
| 357 |
> |
IBGUIInterface. Note: master/detail delay timer does not apply to console |
| 358 |
> |
mode apps. |
| 359 |
> |
|
| 360 |
> |
2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select |
| 361 |
> |
statement. This avoids problems if "Execute Block" is used as the Query. |
| 362 |
> |
|
| 363 |
> |
3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the |
| 364 |
> |
internal SQL tokeniser routines. |
| 365 |
> |
|
| 366 |
> |
4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse |
| 367 |
> |
as a select statement, with or without CTEs. |
| 368 |
> |
|
| 369 |
> |
5. IBSQLParser: parser now recognises the "ROWS" clause. |
| 370 |
> |
|
| 371 |
> |
6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the |
| 372 |
> |
internal SQL tokeniser routines. |
| 373 |
> |
|
| 374 |
> |
7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions |
| 375 |
> |
being raised for valid set statements processed by a data formatter. |
| 376 |
> |
|
| 377 |
> |
8. New published property for TIBDatabase and TIBXServicesConnection. This is |
| 378 |
> |
FirebirdLibraryPathName: string. If not empty it is used to explicitly specify |
| 379 |
> |
the path of the Firebird Library used by the database/services connection. |
| 380 |
> |
|
| 381 |
> |
9. New read only public property for TIBDatabase and TIBXServicesConnection. This |
| 382 |
> |
is FirebirdAPI and returns the IFirebirdAPI interface used by the database/ |
| 383 |
> |
services connection. |
| 384 |
> |
|
| 385 |
> |
10.SQL Property editors now quote parameter names if "Quote identifier" is selected |
| 386 |
> |
or param name is not a valid SQL identifier. |
| 387 |
> |
|
| 388 |
> |
11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive |
| 389 |
> |
view of whether the text box should be editable when no DataSource is specified. |
| 390 |
> |
TIBLookupComboEditBox has been updated to workaround this problem. As long as |
| 391 |
> |
ReadOnly is false, the text box is editable when no DataSource is specified. |
| 392 |
> |
|
| 393 |
> |
12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of |
| 394 |
> |
the FBLIB environment variable. If you do not want to permit this then you |
| 395 |
> |
must modify the Register procedure in the design/IBDBReg.pas unit to remove |
| 396 |
> |
this setting. |
