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. |

+ |

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 |
+ |
|
305 |

1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change. |
