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.
22 +
23 + IBX Change Log  version                                                   (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
24 +
25 + Development version only.

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
85 +
86 +
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
