2 tony 31
3     1. OnCloseUp Event Handler added to TDBLookupProperties
4    
5     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
6     problem with row size when exception is called.
7    
8     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
9    
10     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
11     in a TCustomComboBox and ignores return key if in a TCustomMemo
12    
13     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
14     keyed in i.e. when autocomplete not performed
15    
16 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
17     console mode applications with all LCL required functions (builtin dialogs and
18     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
19     not included in your project, IBX should compile and link with a console mode program.
20     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
21     console mode application or the IDE will automatically assume that your
22     application is GUI based. Instead, you should include the ibexpressconsolemode package.
23 tony 31
24     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
25     to use the built in dialogs and cursor management. IBDialogs is
26 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
27 tony 31 This should be the case for all projects created through the IDE. This is why
28     you do not want to add the ibexpress package to console mode applications. The
29     ibexpressconsolemode package has been created to allow console mode programs
30     to avoid adding LCL dependencies when using IBX, while still having the
31     unit search paths set up correctly.
32    
33 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
34     each project's source file (*.lpr).
35    
36 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
37     exists, you have to first open the package in the IDE and then close it. This
38     adds it to the most recently accessed packages list. To make it permanently
39     available, add the package name to lazarus' staticpackages.inc file.
40    
41 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
42 tony 31
43     7. SQL Parser can now accept quoted strings that include new lines
44    
45     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
46     of text on start of edit. This is particularly useful when tabbing to a
47     column and then inserting text.
48    
49     9. New Examples provided for IB Services and ISQLMonitor.
50    
51     10. Fix error when writing to blob streams that recorded only the last buffer
52     write in the blob stream. In most cases, this did not cause a problem as the
53     IB Blob Stream is written in a single write. However, with the TDBImage, write
54     of a graphic type prefix was lost which caused a problem when the image could
55     not be automatically recognised.
56    
57     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
58 tony 33 already open" errors due to random numbers used for the cursor name being identical.
59 tony 31
60     12. IBTable: corrected error that could result in an "Index out of bounds" error
61     when opening the table and the Primary Key is the last or only column in the
62     table. Thanks to Rick Hoover for the fix.
63    
64 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
65     of "UTF-8", and update list of available database character sets. Existing
66     users should check the current lc_ctype setting in their applications.

68 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
69    
70 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
71     empty Params property.
72    
73     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
74     Link now set up in Loaded method - avoids occasional failure to apply
75     SQL markup on initial open.
76    
77     3. "Employees" example performance improvements when scrolling.
78    
79     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
80     TFrame. Force recaching of selected frame to avoid GTK race (results in a
81     random image cached).
82    
83     5. DBControlGrid: Should now react to changes in panel height at run time.
84    
85     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
86     even when further rows exist.
87    
88     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
89     always be derived from panel height and setting this property can cause confusion.
90     Note for existing projects: to avoid a missing property error at run time,
91     each form using the DBControlGrid must be opened, updated and saved in the IDE
92     in order to remove the property value from the lfm.
93    
94    
95 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
96 tony 27
97     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
98     call Prepare before setting parameter values.
99    
100     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
101    
102     3. Code tidyup and more robust handling of dsql information result vector.
103    
104     4. Support for centralised handling of transaction status changes. TIBTransaction
105     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
106     and "AfterExecQuery". The first three are called after the same event is called
107     for an IBCustomDataSet descendent using the Transaction. The fourth is called
108     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
109     enable monitoring of transaction status changes for a given transaction to be
110     handled in a single place. For example, when a change to the dataset occurs
111     an indicator can be set that shows the user that in order to save changes,
112     the transaction should be committed. Rather than doing this per dataset, this
113     can now be done per transaction.
114    
115     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
116     the dataset is scrolled. However, any changes to the current row are, by default,
117     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
118     have a new property "DataSetCloseAction" that adds automatic posting of changes
119     on dataset close. If this property is set to dcDiscardChanges (default) then the
120     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
121     then IBX will attempt to post any unsaved changes before the dataset is closed
122     (and after the BeforeClose event handler is called). The exception is when the
123     dataset is being closed as a result of a transaction rollback. In this case,
124     no action is taken and any unsaved changes are discarded. This avoids both
125     unnecessary overhead and the risk that a validation error may occur in the Post
126     raising an exception and thereby preventing a rollback.
127    
128     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
129     In earlier versions, the Display Width was set to the maximum byte width rather than the character
130     width. Display Widths are now corrected by dividing by the max byte width per character.
131     For UTF8 character sets, the byte width is four and hence the Display Width will be
132     the byte width divided by 4. The byte width of each character set is determined
133     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
134     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
135    
136     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
137    
138     8. IBLookupComboEditBox: List should now always be restored to full list when the
139     control loses focus. Default Key press default interval reduced to 200ms.
140    
141     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
142     when dataset rows are less than visible rows.
143    
144     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
145     does not exist or DataSet is empty. More responsive on dataset open. New event
146     OnRestorePosition. Column sort disabled if no header row.
147    
148     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
149     while dataset state is dsInsert. Avoids posting errors.
150    
151     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
152     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
153    
154     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
155    
156     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
157     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
158     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
159     always "posts" the current record regardless or whether or not it may be more appropriate
160     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
161     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
162     as the first action of the "Post" method and allows the handler to convert the Post
163     into a Cancel if that is the appropriate action on moving to a different row. This is
164     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
165     raised here, but it may still be more appropriate to validate a post and signal
166     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
167    
168     15. On Unix derived systems, the Firebird library name can now be given as a colon
169     separated list. Each library name on the list is tried in turn, in left to right
170     order with the first found being used as the firebird library. By default, on Linux,
171     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
172     overidden by the FBLIB environment variable or the OnGetLibraryName function.
173    
174     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
175     then it will still attempt to access the database via the Firebird Server and will
176     require a username and password. If only the pathname is given, then the username
177     and password should be omitted and the unix file permissions are used to grant
178     access.
179    
180 tony 33 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
181 tony 23
182     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
183     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
184     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
185 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
186 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
187    
188     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
189 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
190 tony 23 takes place during database access. This may be useful when there are performance issues with
191     the change of cursor. Setting the property to false suppresses the change of cursor.
192    
193     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
194     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
195     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
196     making all changes permanent immediately rather than when the transaction is explicitly
197     committed.
198    
199 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
200 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

202 tony 33 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
203 tony 25
204     Development version only.
205    
206 tony 33 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
207 tony 21
208     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
209     This is typically used during an "OnBeforeOpen" event handler to manipulate the
210     "Where" and "Having" clauses to implement user specified filters of arbitrary
211     complexity.
212    
213     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
214     three new data aware controls dependent on IBX and which make use of the SQL Parser.
215     These are:
216    
217     - TIBLookupComboEditBox
218     - TIBDynamicGrid
219     - TIBTreeview
220    
221     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
222     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
223     to revise the available list and restrict it to items that are prefixed by the
224 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
225 tony 21 newly typed entry to be added to the list dataset and included in the available
226     list items.
227    
228     TIBDynamicGrid is a TDBGrid descendent that provides for:
229     - automatic resizing of selected columns to fill the available row length
230     - automatic positioning and sizing of a "totals" control, typically at the
231     column footer, on a per column basis.
232     - DataSet resorting on header row click, sorting the dataset by the selected column.
233     A second click on the same header cell reversed the sort order.
234     - Support for a "Panel Editor". That is on clicking the indicator column, the row
235     is automatically expanded and a panel superimposed on it. The panel can have any
236     number of child controls, typically data aware controls with the same datasource
237     as the grid allowing for editing of additional fields and more complex editors.
238     - Reselection of the same row following resorting.
239     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
240     Its properties are specified on a per column basis and allows for one or more
241     columns to have their values selected from a list provided by a dataset.
242     Autocomplete and autoinsert are also available. The existing picklist editor
243     is unaffected by the extension.
244    
245     TIBTreeView is a data aware TCustomTreeView.
246    
247     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
248     zero scale will no longer return an error. An Int64 will be returned instead.
249    
250     4. TIBTransaction now has events for Before and After Transaction End and a new function
251     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
252    
253     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
254     repeated multiple times.
255    
256     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
257     check used to get in the way of using Stored Procedures, and "Update or Insert"
258     statements.
259    
260     7. Insert, Modify and Delete property Editors now support Query Generation from
261     Stored Procedures.
262    
263     8. Three new examples illustrate the use of the new IB Controls
264    
265    
266 tony 33 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
267 tony 19
268     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
269     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
270     Gabor Boros for reporting this problem and for testing the improvements).
271    
272     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
273     See readme.field+param.names in the doc folder.
274    
275     3. IBX SQL Editors will now automatically add double quotes around column names when the database
276     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
277    
278     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
279    
280     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
281     actions.
282    
283     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
284     thanks to Yuriy Kopnin for pointing this out).
285    
286     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
287    
288     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
289     for both fields and parameter setting.
290    
291     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
292     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
293    
294     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
295     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
296    
297     11. TIBTable now has a property editor for "MasterFields"
298    
299     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
300     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
301    
302     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
303     of settings is unrecognised. Selecting this radio button has no effect on the settings.
304    
305    
306 tony 17 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
307    
308     1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
309    
310 tony 15 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
311    
312     1. In a TIBCustomDataset descendent, a generator now only sets the value when
313     it is null. This allows for alternative user defined setting of the generator
314    
315     Many thanks to Julio Jiménez for this fix
316    
317     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
318     and suggests that the user may have forgotten to install it.
319    
320 tony 13 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
321    
322     1. Conditional compilation used to limit registration of TIntegerField to
323     Lazarus versions less than 1.1
324    
325     2. When a database connection is created, character set is now by default set
326     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
327     1250 to 1254.
328    
329

331    
332     1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
333    
334    
335 tony 9 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
336 tony 7
337     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
338     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
339    
340     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
341     package is changed to do this (which it should do).
342    
343     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
344    
345     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
346    
347     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
348    
349     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
350    
351     4. Property editors should now correctly resize.
352    
353     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
354     (restored original functionality)
355    
356     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
357     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
