1 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +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 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 >
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's "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 >     Existing users should check to ensure that the "ibexpress" unit is included in
34 >     each project's source file (*.lpr).
35 >
36 >     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 >         Thanks to Julio Jiménez for suggesting support of console mode.
42 >
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 >    already open" errors due to random numbers used for the cursor name being identical.
59 >
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 > 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.
67 >
68 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
69 >
70 > 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 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
96 >
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 > IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
181 >
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 >    corresponds to a row of the linked DataSource. Any data aware control on the
186 >    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 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
190 >   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 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
200 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
201 >
202 > IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
203 >
204 > Development version only.
205 >
206 > IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
207 >
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 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
225 >   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 > IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
267 >
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 >

306 > 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 > 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 > 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 >
