1 tony 35 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

56 tony 31
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 tony 33 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 tony 31
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 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
81 tony 31 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 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
88     each project's source file (*.lpr).
89    
90 tony 31 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 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
96 tony 31
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 tony 33 already open" errors due to random numbers used for the cursor name being identical.
113 tony 31
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 tony 33 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.

122 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
123    
124 tony 29 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 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
150 tony 27
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 tony 33 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
235 tony 23
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 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
240 tony 23 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 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
244 tony 23 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 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
254 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

257 tony 25
258     Development version only.
259    
260 tony 33 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
261 tony 21
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 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
279 tony 21 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 tony 33 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
321 tony 19
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    
359

361    
362     1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
363    
364 tony 15 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
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.
373    
374 tony 13 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
375    
376     1. Conditional compilation used to limit registration of TIntegerField to
377     Lazarus versions less than 1.1
378    
379     2. When a database connection is created, character set is now by default set
380     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
381     1250 to 1254.
382

385    
386     1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
387    
388    
389 tony 9 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
390 tony 7
391     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
392     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
393    
394     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
