1 + IBX Change Log  version                                      (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
2 +
3 + 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
4 +   This is typically used during an "OnBeforeOpen" event handler to manipulate the
5 +   "Where" and "Having" clauses to implement user specified filters of arbitrary
6 +   complexity.
7 +
8 + 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
9 +   three new data aware controls dependent on IBX and which make use of the SQL Parser.
10 +   These are:
11 +
12 +   - TIBLookupComboEditBox
13 +   - TIBDynamicGrid
14 +   - TIBTreeview
15 +
16 +   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
17 +   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
18 +   to revise the available list and restrict it to items that are prefixed by the
19 +   typed text (either case sensitive or case insenstive). Autoinsert allows a
20 +   newly typed entry to be added to the list dataset and included in the available
21 +   list items.
22 +
23 +   TIBDynamicGrid is a TDBGrid descendent that provides for:
24 +   - automatic resizing of selected columns to fill the available row length
25 +   - automatic positioning and sizing of a "totals" control, typically at the
26 +     column footer, on a per column basis.
27 +   - DataSet resorting on header row click, sorting the dataset by the selected column.
28 +     A second click on the same header cell reversed the sort order.
29 +   - Support for a "Panel Editor". That is on clicking the indicator column, the row
30 +     is automatically expanded and a panel superimposed on it. The panel can have any
31 +     number of child controls, typically data aware controls with the same datasource
32 +     as the grid allowing for editing of additional fields and more complex editors.
33 +   - Reselection of the same row following resorting.
34 +   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
35 +     Its properties are specified on a per column basis and allows for one or more
36 +     columns to have their values selected from a list provided by a dataset.
37 +     Autocomplete and autoinsert are also available. The existing picklist editor
38 +     is unaffected by the extension.
39 +
40 +   TIBTreeView is a data aware TCustomTreeView.
41 +
42 + 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
43 +   zero scale will no longer return an error. An Int64 will be returned instead.
44 +
45 + 4. TIBTransaction now has events for Before and After Transaction End and a new function
46 +   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
47 +
48 + 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
49 +   repeated multiple times.
50 +
51 + 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
52 +   check used to get in the way of using Stored Procedures, and "Update or Insert"
53 +   statements.
54 +
55 + 7. Insert, Modify and Delete property Editors now support Query Generation from
56 +   Stored Procedures.
57 +
58 + 8. Three new examples illustrate the use of the new IB Controls
59 +
60 +
61 + IBX Change Log  version                      (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
62 +
63 + 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
64 +   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
65 +   Gabor Boros for reporting this problem and for testing the improvements).
66 +
67 + 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
68 +   See readme.field+param.names in the doc folder.
69 +
70 + 3. IBX SQL Editors will now automatically add double quotes around column names when the database
71 +   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
72 +
73 + 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
74 +
75 + 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
76 +   actions.
77 +
78 + 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
79 +   thanks to Yuriy Kopnin for pointing this out).
80 +
81 + 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
82 +
83 + 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
84 +   for both fields and parameter setting.
85 +
86 + 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
87 +   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
88 +
89 + 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
90 +    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
91 +
92 + 11. TIBTable now has a property editor for "MasterFields"
93 +
94 + 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
95 +    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
96 +
97 + 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
98 +    of settings is unrecognised. Selecting this radio button has no effect on the settings.
99 +  
100 +
101 + IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
102 +
103 + 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
104 +
105 + IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
106 +
107 + 1. In a TIBCustomDataset descendent, a generator now only sets the value when
108 +   it is null. This allows for alternative user defined setting of the generator
109 +
110 +   Many thanks to Julio JimĂ©nez for this fix
111 +
112 + 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
113 +   and suggests that the user may have forgotten to install it.
114 +
115 + IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
116 +
117 + 1. Conditional compilation used to limit registration of TIntegerField to
118 +   Lazarus versions less than 1.1
119 +
120 + 2. When a database connection is created, character set is now by default set
121 +   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
122 +   1250 to 1254.
123 +
124 +
125   IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
126  
127   1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
