1 tony 31 IBX Change Log version (1.3-0) Tue, 14 Jul 2015 16:32:40 +0100
2    
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     6. Cleanup of "Uses" clauses and console mode support. IBX should now support
17     console mode applications with all LCL required functions centralised in the
18     IBDialogs unit. As long as "IBDialogs" is not included in your project, IBX
19     should compile and link with a console mode program. See consolemode example
20     for further guidence. DO NOT add the ibexpress package to a console mode
21     application or the IDE will automatically assume that you application is
22     GUI based. Instead, you should include the ibexpressconsolemode package.
23    
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     included by default if "ibexpress" is in your project source "uses" clause.
27     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     You may find that in order for the IDE to recognise that ibexpressconsolemode
34     exists, you have to first open the package in the IDE and then close it. This
35     adds it to the most recently accessed packages list. To make it permanently
36     available, add the package name to lazarus' staticpackages.inc file.
37    
38     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.
44    
45     7. SQL Parser can now accept quoted strings that include new lines
46    
47     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
48     of text on start of edit. This is particularly useful when tabbing to a
49     column and then inserting text.
50    
51     9. New Examples provided for IB Services and ISQLMonitor.
52    
53     10. Fix error when writing to blob streams that recorded only the last buffer
54     write in the blob stream. In most cases, this did not cause a problem as the
55     IB Blob Stream is written in a single write. However, with the TDBImage, write
56     of a graphic type prefix was lost which caused a problem when the image could
57     not be automatically recognised.
58    
59     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
60     already open" errors due to random numbers being identical.
61    
62     12. IBTable: corrected error that could result in an "Index out of bounds" error
63     when opening the table and the Primary Key is the last or only column in the
64     table. Thanks to Rick Hoover for the fix.
65    
66 tony 29 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
67    
68     1. Firebird Services: avoid List Index error when opening a service with an
69     empty Params property.
70    
71     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
72     Link now set up in Loaded method - avoids occasional failure to apply
73     SQL markup on initial open.
74    
75     3. "Employees" example performance improvements when scrolling.
76    
77     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
78     TFrame. Force recaching of selected frame to avoid GTK race (results in a
79     random image cached).
80    
81     5. DBControlGrid: Should now react to changes in panel height at run time.
82    
83     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
84     even when further rows exist.
85    
86     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
87     always be derived from panel height and setting this property can cause confusion.
88     Note for existing projects: to avoid a missing property error at run time,
89     each form using the DBControlGrid must be opened, updated and saved in the IDE
90     in order to remove the property value from the lfm.
91    
92    
93 tony 27 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
94    
95     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
96     call Prepare before setting parameter values.
97    
98     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
99    
100     3. Code tidyup and more robust handling of dsql information result vector.
101    
102     4. Support for centralised handling of transaction status changes. TIBTransaction
103     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
104     and "AfterExecQuery". The first three are called after the same event is called
105     for an IBCustomDataSet descendent using the Transaction. The fourth is called
106     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
107     enable monitoring of transaction status changes for a given transaction to be
108     handled in a single place. For example, when a change to the dataset occurs
109     an indicator can be set that shows the user that in order to save changes,
110     the transaction should be committed. Rather than doing this per dataset, this
111     can now be done per transaction.
112    
113     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
114     the dataset is scrolled. However, any changes to the current row are, by default,
115     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
116     have a new property "DataSetCloseAction" that adds automatic posting of changes
117     on dataset close. If this property is set to dcDiscardChanges (default) then the
118     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
119     then IBX will attempt to post any unsaved changes before the dataset is closed
120     (and after the BeforeClose event handler is called). The exception is when the
121     dataset is being closed as a result of a transaction rollback. In this case,
122     no action is taken and any unsaved changes are discarded. This avoids both
123     unnecessary overhead and the risk that a validation error may occur in the Post
124     raising an exception and thereby preventing a rollback.
125    
126     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
127     In earlier versions, the Display Width was set to the maximum byte width rather than the character
128     width. Display Widths are now corrected by dividing by the max byte width per character.
129     For UTF8 character sets, the byte width is four and hence the Display Width will be
130     the byte width divided by 4. The byte width of each character set is determined
131     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
132     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
133    
134     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
135    
136     8. IBLookupComboEditBox: List should now always be restored to full list when the
137     control loses focus. Default Key press default interval reduced to 200ms.
138    
139     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
140     when dataset rows are less than visible rows.
141    
142     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
143     does not exist or DataSet is empty. More responsive on dataset open. New event
144     OnRestorePosition. Column sort disabled if no header row.
145    
146     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
147     while dataset state is dsInsert. Avoids posting errors.
148    
149     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
150     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
151    
152     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
153    
154     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
155     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
156     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
157     always "posts" the current record regardless or whether or not it may be more appropriate
158     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
159     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
160     as the first action of the "Post" method and allows the handler to convert the Post
161     into a Cancel if that is the appropriate action on moving to a different row. This is
162     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
163     raised here, but it may still be more appropriate to validate a post and signal
164     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
165    
166     15. On Unix derived systems, the Firebird library name can now be given as a colon
167     separated list. Each library name on the list is tried in turn, in left to right
168     order with the first found being used as the firebird library. By default, on Linux,
169     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
170     overidden by the FBLIB environment variable or the OnGetLibraryName function.
171    
172     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
173     then it will still attempt to access the database via the Firebird Server and will
174     require a username and password. If only the pathname is given, then the username
175     and password should be omitted and the unix file permissions are used to grant
176     access.
177    
178 tony 25 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
179 tony 23
180     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
181     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
182     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
183 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
184 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
185    
186     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
187 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
188 tony 23 takes place during database access. This may be useful when there are performance issues with
189     the change of cursor. Setting the property to false suppresses the change of cursor.
190    
191     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
192     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
193     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
194     making all changes permanent immediately rather than when the transaction is explicitly
195     committed.
196    
197 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
198 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

200 tony 25 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
201    
202     Development version only.
203    
204 tony 21 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
205    
206     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
207     This is typically used during an "OnBeforeOpen" event handler to manipulate the
208     "Where" and "Having" clauses to implement user specified filters of arbitrary
209     complexity.
210    
211     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
212     three new data aware controls dependent on IBX and which make use of the SQL Parser.
213     These are:
214    
215     - TIBLookupComboEditBox
216     - TIBDynamicGrid
217     - TIBTreeview
218    
219     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
220     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
221     to revise the available list and restrict it to items that are prefixed by the
222 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
223 tony 21 newly typed entry to be added to the list dataset and included in the available
224     list items.
225    
226     TIBDynamicGrid is a TDBGrid descendent that provides for:
227     - automatic resizing of selected columns to fill the available row length
228     - automatic positioning and sizing of a "totals" control, typically at the
229     column footer, on a per column basis.
230     - DataSet resorting on header row click, sorting the dataset by the selected column.
231     A second click on the same header cell reversed the sort order.
232     - Support for a "Panel Editor". That is on clicking the indicator column, the row
233     is automatically expanded and a panel superimposed on it. The panel can have any
234     number of child controls, typically data aware controls with the same datasource
235     as the grid allowing for editing of additional fields and more complex editors.
236     - Reselection of the same row following resorting.
237     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
238     Its properties are specified on a per column basis and allows for one or more
239     columns to have their values selected from a list provided by a dataset.
240     Autocomplete and autoinsert are also available. The existing picklist editor
241     is unaffected by the extension.
242    
243     TIBTreeView is a data aware TCustomTreeView.
244    
245     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
246     zero scale will no longer return an error. An Int64 will be returned instead.
247    
248     4. TIBTransaction now has events for Before and After Transaction End and a new function
249     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
250    
251     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
252     repeated multiple times.
253    
254     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
255     check used to get in the way of using Stored Procedures, and "Update or Insert"
256     statements.
257    
258     7. Insert, Modify and Delete property Editors now support Query Generation from
259     Stored Procedures.
260    
261     8. Three new examples illustrate the use of the new IB Controls
262    
263    
264 tony 19 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
265    
266     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
267     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
268     Gabor Boros for reporting this problem and for testing the improvements).
269    
270     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
271     See readme.field+param.names in the doc folder.
272    
273     3. IBX SQL Editors will now automatically add double quotes around column names when the database
274     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
275    
276     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
277    
278     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
279     actions.
280    
281     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
282     thanks to Yuriy Kopnin for pointing this out).
283    
284     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
285    
286     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
287     for both fields and parameter setting.
288    
289     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
290     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
291    
292     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
293     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
294    
295     11. TIBTable now has a property editor for "MasterFields"
296    
297     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
298     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
299    
300     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
301     of settings is unrecognised. Selecting this radio button has no effect on the settings.
302    
303    
304 tony 17 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
305    
306     1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
307    
308 tony 15 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
309    
310     1. In a TIBCustomDataset descendent, a generator now only sets the value when
311     it is null. This allows for alternative user defined setting of the generator
312    
313     Many thanks to Julio Jiménez for this fix
314    
315     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
316     and suggests that the user may have forgotten to install it.
317    
318 tony 13 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
319    
320     1. Conditional compilation used to limit registration of TIntegerField to
321     Lazarus versions less than 1.1
322    
323     2. When a database connection is created, character set is now by default set
324     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
325     1250 to 1254.
326    
327    
328 tony 11 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
329    
330     1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
331    
332    
333 tony 9 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
334 tony 7
335     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
336     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
337    
338     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
339     package is changed to do this (which it should do).
340    
341     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
342    
343     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
344    
345     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
346    
347     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
348    
349     4. Property editors should now correctly resize.
350    
351     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
352     (restored original functionality)
353    
354     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
355     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
