1 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
2 +
3 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
4 +
5 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
6 +
7 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
8 +
9 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
10 +   i.e. when it is a calculated field
11 +
12 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
13 +   This problem was due to a race condition between recalculating row heights and
14 +   determining which row was selected by the mouse click. The row height calculation
15 +   is now deferred by an extra trip round the message loop allowing the row to
16 +   be always calculated on the current grid layout rather than risking it being
17 +   calculated on the grid layout after the expanded row has been shrunk.
18 +
19 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
20 +   Windows.
21 +
22 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
23 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
24 +   to be determined at runtime.
25 +
26 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
27 +   TWideStringField. This field type is used with the character size reported by Firebird is two.
28 +
29 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
30 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
31 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField).
32 +
33 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
34 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
35 +   implies no truncation.
36 +
37 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
38 +
39 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
40 +   (avoids "Not in Edit Mode" error).
41 +
42 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
43 +
44 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
45 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
46 +
47 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
48 +
49 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
50 +
51 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
52 +
53 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
54 +
55 + IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
56 +
57 + 1.   OnCloseUp Event Handler added to TDBLookupProperties
58 +
59 + 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
60 +     problem with row size when exception is called.
61 +
62 + 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
63 +
64 + 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
65 +     in a TCustomComboBox and ignores return key if in a TCustomMemo
66 +
67 + 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
68 +     keyed in i.e. when autocomplete not performed
69 +
70 + 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
71 +     console mode applications with all LCL required functions (builtin dialogs and
72 +     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
73 +     not included in your project, IBX should compile and link with a console mode program.
74 +     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
75 +     console mode application or the IDE will automatically assume that your
76 +     application is GUI based. Instead, you should include the ibexpressconsolemode package.
77 +
78 +     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
79 +     to use the built in dialogs and cursor management. IBDialogs is
80 +     included by default if "ibexpress" is in your project source's "uses" clause.
81 +     This should be the case for all projects created through the IDE. This is why
82 +     you do not want to add the ibexpress package to console mode applications. The
83 +     ibexpressconsolemode package has been created to allow console mode programs
84 +     to avoid adding LCL dependencies when using IBX, while still having the
85 +     unit search paths set up correctly.
86 +
87 +     Existing users should check to ensure that the "ibexpress" unit is included in
88 +     each project's source file (*.lpr).
89 +
90 +     You may find that in order for the IDE to recognise that ibexpressconsolemode
91 +     exists, you have to first open the package in the IDE and then close it. This
92 +     adds it to the most recently accessed packages list. To make it permanently
93 +     available, add the package name to lazarus' staticpackages.inc file.
94 +
95 +         Thanks to Julio Jiménez for suggesting support of console mode.
96 +
97 + 7.   SQL Parser can now accept quoted strings that include new lines
98 +
99 + 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
100 +     of text on start of edit. This is particularly useful when tabbing to a
101 +     column and then inserting text.
102 +
103 + 9.   New Examples provided for IB Services and ISQLMonitor.
104 +
105 + 10. Fix error when writing to blob streams that recorded only the last buffer
106 +    write in the blob stream. In most cases, this did not cause a problem as the
107 +    IB Blob Stream is written in a single write. However, with the TDBImage, write
108 +    of a graphic type prefix was lost which caused a problem when the image could
109 +        not be automatically recognised.
110 +
111 + 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
112 +    already open" errors due to random numbers used for the cursor name being identical.
113 +
114 + 12. IBTable: corrected error that could result in an "Index out of bounds" error
115 +    when opening the table and the Primary Key is the last or only column in the
116 +    table. Thanks to Rick Hoover for the fix.
117 +
118 + 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
119 +    of "UTF-8", and update list of available database character sets. Existing
120 +    users should check the current lc_ctype setting in their applications.
121 +
122 + IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
123 +
124 + 1.  Firebird Services: avoid List Index error when opening a service with an
125 +    empty Params property.
126 +
127 + 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
128 +    Link now set up in Loaded method - avoids occasional failure to apply
129 +    SQL markup on initial open.
130 +
131 + 3.  "Employees" example performance improvements when scrolling.
132 +
133 + 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
134 +    TFrame. Force recaching of selected frame to avoid GTK race (results in a
135 +    random image cached).
136 +
137 + 5.  DBControlGrid: Should now react to changes in panel height at run time.
138 +
139 + 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
140 +    even when further rows exist.
141 +
142 + 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
143 +    always be derived from panel height and setting this property can cause confusion.
144 +    Note for existing projects: to avoid a missing property error at run time,
145 +    each form using the DBControlGrid must be opened, updated and saved in the IDE
146 +    in order to remove the property value from the lfm.
147 +
148 +
149 + IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
150 +
151 + 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
152 +    call Prepare before setting parameter values.
153 +
154 + 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
155 +
156 + 3.  Code tidyup and more robust handling of dsql information result vector.
157 +
158 + 4.  Support for centralised handling of transaction status changes. TIBTransaction
159 +    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
160 +    and "AfterExecQuery". The first three are called after the same event is called
161 +    for an IBCustomDataSet descendent using the Transaction. The fourth is called
162 +    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
163 +    enable monitoring of transaction status changes for a given transaction to be
164 +    handled in a single place. For example, when a change to the dataset occurs
165 +    an indicator can be set that shows the user that in order to save changes,
166 +    the transaction should be committed.  Rather than doing this per dataset, this
167 +    can now be done per transaction.
168 +
169 + 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
170 +    the dataset is scrolled. However, any changes to the current row are, by default,
171 +    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
172 +    have a new property "DataSetCloseAction" that adds automatic posting of changes
173 +    on dataset close. If this property is set to dcDiscardChanges (default) then the
174 +    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
175 +    then IBX will attempt to post any unsaved changes before the dataset is closed
176 +    (and after the BeforeClose event handler is called). The exception is when the
177 +    dataset is being closed as a result of a transaction rollback. In this case,
178 +    no action is taken and any unsaved  changes are discarded. This avoids both
179 +    unnecessary overhead and the risk that a validation error may occur in the Post
180 +    raising an exception and thereby preventing a rollback.
181 +
182 + 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
183 +    In earlier versions, the Display Width was set to the maximum byte width rather than the character
184 +    width. Display Widths are now corrected by dividing by the max byte width per character.
185 +    For UTF8 character sets, the byte width is four and hence the Display Width will be
186 +    the byte width divided by 4. The byte width of each character set is determined
187 +    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
188 +    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
189 +
190 + 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
191 +
192 + 8.  IBLookupComboEditBox: List should now always be restored to full list when the
193 +    control loses focus. Default Key press default interval reduced to 200ms.
194 +
195 + 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
196 +    when dataset rows are less than visible rows.
197 +
198 + 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
199 +    does not exist or DataSet is empty. More responsive on dataset open. New event
200 +    OnRestorePosition. Column sort disabled if no header row.
201 +
202 + 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
203 +    while dataset state is dsInsert. Avoids posting errors.
204 +
205 + 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
206 +    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
207 +
208 + 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
209 +
210 + 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
211 +    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
212 +    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
213 +    always "posts" the current record regardless or whether or not it may be more appropriate
214 +    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
215 +    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
216 +    as the first action of the "Post" method and allows the handler to convert the Post
217 +    into a Cancel if that is the appropriate action on moving to a different row. This is
218 +    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
219 +    raised here, but it may still be more appropriate to validate a post and signal
220 +    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
221 +
222 + 15. On Unix derived systems, the Firebird library name can now be given as a colon
223 +    separated list. Each library name on the list is tried in turn, in left to right
224 +    order with the first found being used as the firebird library. By default, on Linux,
225 +    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
226 +    overidden by the FBLIB environment variable or the OnGetLibraryName function.
227 +
228 +    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
229 +    then it will still attempt to access the database via the Firebird Server and will
230 +    require a username and password. If only the pathname is given, then the username
231 +    and password should be omitted and the unix file permissions are used to grant
232 +    access.
233 +
234 + IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
235 +
236 + 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
237 +    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
238 +    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
239 +    corresponds to a row of the linked DataSource. Any data aware control on the
240 +    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
241 +
242 + 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
243 +   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
244 +   takes place during database access. This may be useful when there are performance issues with
245 +   the change of cursor. Setting the property to false suppresses the change of cursor.
246 +
247 + 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
248 +   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
249 +   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
250 +   making all changes permanent immediately rather than when the transaction is explicitly
251 +   committed.
252 +
253 + 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
254 +   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
255 +
256 + IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
257 +
258 + Development version only.
259 +
260 + IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
261 +
262 + 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
263 +   This is typically used during an "OnBeforeOpen" event handler to manipulate the
264 +   "Where" and "Having" clauses to implement user specified filters of arbitrary
265 +   complexity.
266 +
267 + 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
268 +   three new data aware controls dependent on IBX and which make use of the SQL Parser.
269 +   These are:
270 +
271 +   - TIBLookupComboEditBox
272 +   - TIBDynamicGrid
273 +   - TIBTreeview
274 +
275 +   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
276 +   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
277 +   to revise the available list and restrict it to items that are prefixed by the
278 +   typed text (either case sensitive or case insensitive). Autoinsert allows a
279 +   newly typed entry to be added to the list dataset and included in the available
280 +   list items.
281 +
282 +   TIBDynamicGrid is a TDBGrid descendent that provides for:
283 +   - automatic resizing of selected columns to fill the available row length
284 +   - automatic positioning and sizing of a "totals" control, typically at the
285 +     column footer, on a per column basis.
286 +   - DataSet resorting on header row click, sorting the dataset by the selected column.
287 +     A second click on the same header cell reversed the sort order.
288 +   - Support for a "Panel Editor". That is on clicking the indicator column, the row
289 +     is automatically expanded and a panel superimposed on it. The panel can have any
290 +     number of child controls, typically data aware controls with the same datasource
291 +     as the grid allowing for editing of additional fields and more complex editors.
292 +   - Reselection of the same row following resorting.
293 +   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
294 +     Its properties are specified on a per column basis and allows for one or more
295 +     columns to have their values selected from a list provided by a dataset.
296 +     Autocomplete and autoinsert are also available. The existing picklist editor
297 +     is unaffected by the extension.
298 +
299 +   TIBTreeView is a data aware TCustomTreeView.
300 +
301 + 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
302 +   zero scale will no longer return an error. An Int64 will be returned instead.
303 +
304 + 4. TIBTransaction now has events for Before and After Transaction End and a new function
305 +   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
306 +
307 + 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
308 +   repeated multiple times.
309 +
310 + 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
311 +   check used to get in the way of using Stored Procedures, and "Update or Insert"
312 +   statements.
313 +
314 + 7. Insert, Modify and Delete property Editors now support Query Generation from
315 +   Stored Procedures.
316 +
317 + 8. Three new examples illustrate the use of the new IB Controls
318 +
319 +
320 + IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
321 +
322 + 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
323 +   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
324 +   Gabor Boros for reporting this problem and for testing the improvements).
325 +
326 + 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
327 +   See readme.field+param.names in the doc folder.
328 +
329 + 3. IBX SQL Editors will now automatically add double quotes around column names when the database
330 +   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
331 +
332 + 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
333 +
334 + 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
335 +   actions.
336 +
337 + 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
338 +   thanks to Yuriy Kopnin for pointing this out).
339 +
340 + 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
341 +
342 + 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
343 +   for both fields and parameter setting.
344 +
345 + 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
346 +   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
347 +
348 + 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
349 +    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
350 +
351 + 11. TIBTable now has a property editor for "MasterFields"
352 +
353 + 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
354 +    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
355 +
356 + 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
357 +    of settings is unrecognised. Selecting this radio button has no effect on the settings.
358 +

365 +
366 + 1. In a TIBCustomDataset descendent, a generator now only sets the value when
367 +   it is null. This allows for alternative user defined setting of the generator
368 +
369 +   Many thanks to Julio Jiménez for this fix
370 +
371 + 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
372 +   and suggests that the user may have forgotten to install it.
