1 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
2
3 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
4 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
5 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
6 correspondes to a row of the linked DataSource. Any data aware control on the
7 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
8
9 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
10 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
11 takes place during database access. This may be useful when there are performance issues with
12 the change of cursor. Setting the property to false suppresses the change of cursor.
13
14 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
15 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
16 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
17 making all changes permanent immediately rather than when the transaction is explicitly
18 committed.
19
20 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
21 using the legacy Firebird API. Thanks to Gabor Boros for helping to this feature.

27 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
28
29 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
30 This is typically used during an "OnBeforeOpen" event handler to manipulate the
31 "Where" and "Having" clauses to implement user specified filters of arbitrary
32 complexity.
33
34 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
35 three new data aware controls dependent on IBX and which make use of the SQL Parser.
36 These are:
37
38 - TIBLookupComboEditBox
39 - TIBDynamicGrid
40 - TIBTreeview
41
42 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
43 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
44 to revise the available list and restrict it to items that are prefixed by the
45 typed text (either case sensitive or case insensitive). Autoinsert allows a
46 newly typed entry to be added to the list dataset and included in the available
47 list items.
48
49 TIBDynamicGrid is a TDBGrid descendent that provides for:
50 - automatic resizing of selected columns to fill the available row length
51 - automatic positioning and sizing of a "totals" control, typically at the
52 column footer, on a per column basis.
53 - DataSet resorting on header row click, sorting the dataset by the selected column.
54 A second click on the same header cell reversed the sort order.
55 - Support for a "Panel Editor". That is on clicking the indicator column, the row
56 is automatically expanded and a panel superimposed on it. The panel can have any
57 number of child controls, typically data aware controls with the same datasource
58 as the grid allowing for editing of additional fields and more complex editors.
59 - Reselection of the same row following resorting.
60 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
61 Its properties are specified on a per column basis and allows for one or more
62 columns to have their values selected from a list provided by a dataset.
63 Autocomplete and autoinsert are also available. The existing picklist editor
64 is unaffected by the extension.
65
66 TIBTreeView is a data aware TCustomTreeView.
67
68 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
69 zero scale will no longer return an error. An Int64 will be returned instead.
70
71 4. TIBTransaction now has events for Before and After Transaction End and a new function
72 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
73
74 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
75 repeated multiple times.
76
77 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
78 check used to get in the way of using Stored Procedures, and "Update or Insert"
79 statements.
80
81 7. Insert, Modify and Delete property Editors now support Query Generation from
82 Stored Procedures.
83
84 8. Three new examples illustrate the use of the new IB Controls

87 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
88
89 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
90 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
91 Gabor Boros for reporting this problem and for testing the improvements).
92
93 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
94 See readme.field+param.names in the doc folder.
95
96 3. IBX SQL Editors will now automatically add double quotes around column names when the database
97 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
98
99 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
100
101 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
102 actions.
103
104 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
105 thanks to Yuriy Kopnin for pointing this out).
106
107 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
108
109 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
110 for both fields and parameter setting.
111
112 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
113 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
114
115 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
116 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
117
118 11. TIBTable now has a property editor for "MasterFields"
119
120 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
121 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
122
123 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
124 of settings is unrecognised. Selecting this radio button has no effect on the settings.
125
126
127 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
128
129 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
130
131 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
132
133 1. In a TIBCustomDataset descendent, a generator now only sets the value when
134 it is null. This allows for alternative user defined setting of the generator
135
136 Many thanks to Julio Jiménez for this fix
137
138 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
139 and suggests that the user may have forgotten to install it.
140
141 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
142
143 1. Conditional compilation used to limit registration of TIntegerField to
144 Lazarus versions less than 1.1
145
146 2. When a database connection is created, character set is now by default set
147 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
148 1250 to 1254.
149
150
151 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
152
153 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
154
155
156 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
157
158 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
159 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
160
161 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
162 package is changed to do this (which it should do).
163
164 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
165
166 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
167
168 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
169
170 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
171
172 4. Property editors should now correctly resize.
173
174 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
175 (restored original functionality)
176
177 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
178 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
