+IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
-+
-+
+. Unix: If Firebird Embedded Server shared object is loaded and a local database
-+
+   path is given and database attach fails due to access permission issues on the
-+
+   temp directory or security database, then the attach is retried with "localhost:"
-+
+   prefixing the databasename. This should avoid problems when the database has to
-+
+   be accessed by a local (e.g. classic) server and libfbembed is used.
-+
-+
+. Windows: revised search order for Firebird DLL:
-+
+     i.   The Firebird Embedded Server in the application Directory.
-+
+     ii.  If the FIREBIRD environment variable is set then the directory this
-+
+          points to is searched for the FB Client DLL and then then underlying
-+
+          "bin" directory.
-+
+     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
-+
+          is used to locate the Firebird installation directory and the underlying
-+
+          "bin" directory is searched for the FB Client DLL.
-+
+     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
-+
+          are searched for the FB Client DLL.
-+
+     v.   The PATH Environment variable is used to search for the FB Client DLL.
-+
+     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
-+
-+
+. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
-+
+   See doc/readme.scriptengine and example applications.
-+
-+
+. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
-+
+   simplify the use of the embedded firebird server on both Linux and Windows platforms.
-+
+   See dpc/readme.localdatabase and example applications.
-+
-+
+. IBDynamicGrid: Reordering on column header click should now also work for
-+
+   dynamic columns.
-+
-+
+. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
-+
+   between incrementing/decrementing the lock count and signalling the event.
-+
-+
+IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
-+
-+
+.3.2 was never formally released and only made available as beta copies.
-+
-+
+. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
-+
-+
+. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
-+
-+
+. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
-+
-+
+. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
-+
+   i.e. when it is a calculated field
-+
-+
+. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
-+
+   This problem was due to a race condition between recalculating row heights and
-+
+   determining which row was selected by the mouse click. The row height calculation
-+
+   is now deferred by an extra trip round the message loop allowing the row to
-+
+   be always calculated on the current grid layout rather than risking it being
-+
+   calculated on the grid layout after the expanded row has been shrunk.
-+
-+
+. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
-+
+   Windows.
-+
-+
+. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
-+
+   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
-+
+   to be determined at runtime. See doc/readme.charactersets.html.
-+
-+
+. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
-+
+   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
-+
-+
+. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
-+
+   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
-+
+, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
-+
-+
+   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
-+
+   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
-+
+   implies no truncation.
-+
-+
+. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
-+
-+
+. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
-+
+   (avoids "Not in Edit Mode" error).
-+
-+
+. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
-+
-+
+. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
-+
+    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
-+
-+
+. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
-+
-+
+. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
-+
-+
+. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
-+
-+
+. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
-+
-+
+IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
-+
-+
+.   OnCloseUp Event Handler added to TDBLookupProperties
-+
-+
+.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
-+
+     problem with row size when exception is called.
-+
-+
+.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
-+
-+
+.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
-+
+     in a TCustomComboBox and ignores return key if in a TCustomMemo
-+
-+
+.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
-+
+     keyed in i.e. when autocomplete not performed
-+
-+
+.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
-+
+     console mode applications with all LCL required functions (builtin dialogs and
-+
+     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
-+
+     not included in your project, IBX should compile and link with a console mode program.
-+
+     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
-+
+     console mode application or the IDE will automatically assume that your
-+
+     application is GUI based. Instead, you should include the ibexpressconsolemode package.
-+
-+
+     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
-+
+     to use the built in dialogs and cursor management. IBDialogs is
-+
+     included by default if "ibexpress" is in your project source's "uses" clause.
-+
+     This should be the case for all projects created through the IDE. This is why
-+
+     you do not want to add the ibexpress package to console mode applications. The
-+
+     ibexpressconsolemode package has been created to allow console mode programs
-+
+     to avoid adding LCL dependencies when using IBX, while still having the
-+
+     unit search paths set up correctly.
-+
-+
+     Existing users should check to ensure that the "ibexpress" unit is included in
-+
+     each project's source file (*.lpr).
-+
-+
+     You may find that in order for the IDE to recognise that ibexpressconsolemode
-+
+     exists, you have to first open the package in the IDE and then close it. This
-+
+     adds it to the most recently accessed packages list. To make it permanently
-+
+     available, add the package name to lazarus' staticpackages.inc file.
-+
-+
+         Thanks to Julio Jiménez for suggesting support of console mode.
-+
-+
+.   SQL Parser can now accept quoted strings that include new lines
-+
-+
+.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
-+
+     of text on start of edit. This is particularly useful when tabbing to a
-+
+     column and then inserting text.
-+
-+
+.   New Examples provided for IB Services and ISQLMonitor.
-+
-+
+. Fix error when writing to blob streams that recorded only the last buffer
-+
+    write in the blob stream. In most cases, this did not cause a problem as the
-+
+    IB Blob Stream is written in a single write. However, with the TDBImage, write
-+
+    of a graphic type prefix was lost which caused a problem when the image could
-+
+        not be automatically recognised.
-+
-+
+. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
-+
+    already open" errors due to random numbers used for the cursor name being identical.
-+
-+
+. IBTable: corrected error that could result in an "Index out of bounds" error
-+
+    when opening the table and the Primary Key is the last or only column in the
-+
+    table. Thanks to Rick Hoover for the fix.
-+
-+
+. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
-+
+    of "UTF-8", and update list of available database character sets. Existing
-+
+    users should check the current lc_ctype setting in their applications.
-+
-+
+IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
-+
-+
+.  Firebird Services: avoid List Index error when opening a service with an
-+
+    empty Params property.
-+
-+
+.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
-+
+    Link now set up in Loaded method - avoids occasional failure to apply
-+
+    SQL markup on initial open.
-+
-+
+.  "Employees" example performance improvements when scrolling.
-+
-+
+.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
-+
+    TFrame. Force recaching of selected frame to avoid GTK race (results in a
-+
+    random image cached).
-+
-+
+.  DBControlGrid: Should now react to changes in panel height at run time.
-+
-+
+.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
-+
+    even when further rows exist.
-+
-+
+.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
-+
+    always be derived from panel height and setting this property can cause confusion.
-+
+    Note for existing projects: to avoid a missing property error at run time,
-+
+    each form using the DBControlGrid must be opened, updated and saved in the IDE
-+
+    in order to remove the property value from the lfm.
-+
-+
-+
+IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
-+
-+
+.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
-+
+    call Prepare before setting parameter values.
-+
-+
+.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
-+
-+
+.  Code tidyup and more robust handling of dsql information result vector.
-+
-+
+.  Support for centralised handling of transaction status changes. TIBTransaction
-+
+    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
-+
+    and "AfterExecQuery". The first three are called after the same event is called
-+
+    for an IBCustomDataSet descendent using the Transaction. The fourth is called
-+
+    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
-+
+    enable monitoring of transaction status changes for a given transaction to be
-+
+    handled in a single place. For example, when a change to the dataset occurs
-+
+    an indicator can be set that shows the user that in order to save changes,
-+
+    the transaction should be committed.  Rather than doing this per dataset, this
-+
+    can now be done per transaction.
-+
-+
+.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
-+
+    the dataset is scrolled. However, any changes to the current row are, by default,
-+
+    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
-+
+    have a new property "DataSetCloseAction" that adds automatic posting of changes
-+
+    on dataset close. If this property is set to dcDiscardChanges (default) then the
-+
+    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
-+
+    then IBX will attempt to post any unsaved changes before the dataset is closed
-+
+    (and after the BeforeClose event handler is called). The exception is when the
-+
+    dataset is being closed as a result of a transaction rollback. In this case,
-+
+    no action is taken and any unsaved  changes are discarded. This avoids both
-+
+    unnecessary overhead and the risk that a validation error may occur in the Post
-+
+    raising an exception and thereby preventing a rollback.
-+
-+
+.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
-+
+    In earlier versions, the Display Width was set to the maximum byte width rather than the character
-+
+    width. Display Widths are now corrected by dividing by the max byte width per character.
-+
+    For UTF8 character sets, the byte width is four and hence the Display Width will be
-+
+    the byte width divided by 4. The byte width of each character set is determined
-+
+    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
-+
+    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
-+
-+
+.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
-+
-+
+.  IBLookupComboEditBox: List should now always be restored to full list when the
-+
+    control loses focus. Default Key press default interval reduced to 200ms.
-+
-+
+.  DBControlGrid: Ensure that selection is changed to newly appended row, even
-+
+    when dataset rows are less than visible rows.
-+
-+
+. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
-+
+    does not exist or DataSet is empty. More responsive on dataset open. New event
-+
+    OnRestorePosition. Column sort disabled if no header row.
-+
-+
+. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
-+
+    while dataset state is dsInsert. Avoids posting errors.
-+
-+
+. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
-+
+    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
-+
-+
+. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
-+
-+
+. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
-+
+    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
-+
+    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
-+
+    always "posts" the current record regardless or whether or not it may be more appropriate
-+
+    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
-+
+    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
-+
+    as the first action of the "Post" method and allows the handler to convert the Post
-+
+    into a Cancel if that is the appropriate action on moving to a different row. This is
-+
+    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
-+
+    raised here, but it may still be more appropriate to validate a post and signal
-+
+    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
-+
-+
+. On Unix derived systems, the Firebird library name can now be given as a colon
-+
+    separated list. Each library name on the list is tried in turn, in left to right
-+
+    order with the first found being used as the firebird library. By default, on Linux,
-+
+    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
-+
+    overidden by the FBLIB environment variable or the OnGetLibraryName function.
-+
-+
+    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
-+
+    then it will still attempt to access the database via the Firebird Server and will
-+
+    require a username and password. If only the pathname is given, then the username
-+
+    and password should be omitted and the unix file permissions are used to grant
-+
+    access.
-+
-+
+IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
-+
-+
+.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
-+
+    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
-+
+    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
-+
+    corresponds to a row of the linked DataSource. Any data aware control on the
-+
+    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
-+
-+
+. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
-+
+   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
-+
+   takes place during database access. This may be useful when there are performance issues with
-+
+   the change of cursor. Setting the property to false suppresses the change of cursor.
-+
-+
+. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
-+
+   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
-+
+   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
-+
+   making all changes permanent immediately rather than when the transaction is explicitly
-+
+   committed.
-+
-+
+. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
-+
+   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
-+
-+
+IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
-+
-+
+Development version only.
-+
-+
+IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
-+
-+
+. An internal select SQL Parser is now available for TIBCustomDataset descendents.
-+
+   This is typically used during an "OnBeforeOpen" event handler to manipulate the
-+
+   "Where" and "Having" clauses to implement user specified filters of arbitrary
-+
+   complexity.
-+
-+
+. A new Component Palette entry "Firebird Data Controls" is now available. This has
-+
+   three new data aware controls dependent on IBX and which make use of the SQL Parser.
-+
+   These are:
-+
-+
+   - TIBLookupComboEditBox
-+
+   - TIBDynamicGrid
-+
+   - TIBTreeview
-+
-+
+   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
-+
+   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
-+
+   to revise the available list and restrict it to items that are prefixed by the
-+
+   typed text (either case sensitive or case insensitive). Autoinsert allows a
-+
+   newly typed entry to be added to the list dataset and included in the available
-+
+   list items.
-+
-+
+   TIBDynamicGrid is a TDBGrid descendent that provides for:
-+
+   - automatic resizing of selected columns to fill the available row length
-+
+   - automatic positioning and sizing of a "totals" control, typically at the
-+
+     column footer, on a per column basis.
-+
+   - DataSet resorting on header row click, sorting the dataset by the selected column.
-+
+     A second click on the same header cell reversed the sort order.
-+
+   - Support for a "Panel Editor". That is on clicking the indicator column, the row
-+
+     is automatically expanded and a panel superimposed on it. The panel can have any
-+
+     number of child controls, typically data aware controls with the same datasource
-+
+     as the grid allowing for editing of additional fields and more complex editors.
-+
+   - Reselection of the same row following resorting.
-+
+   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
-+
+     Its properties are specified on a per column basis and allows for one or more
-+
+     columns to have their values selected from a list provided by a dataset.
-+
+     Autocomplete and autoinsert are also available. The existing picklist editor
-+
+     is unaffected by the extension.
-+
-+
+   TIBTreeView is a data aware TCustomTreeView.
-+
-+
+. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
-+
+   zero scale will no longer return an error. An Int64 will be returned instead.
-+
-+
+. TIBTransaction now has events for Before and After Transaction End and a new function
-+
+   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
-+
-+
+. TIBQuery can now handle correctly queries which contain the same keyword parameter
-+
+   repeated multiple times.
-+
-+
+. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
-+
+   check used to get in the way of using Stored Procedures, and "Update or Insert"
-+
+   statements.
-+
-+
+. Insert, Modify and Delete property Editors now support Query Generation from
-+
+   Stored Procedures.
-+
-+
+. Three new examples illustrate the use of the new IB Controls
-+
-+
-+
+IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
-+
-+
+. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
-+
+   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
-+
+   Gabor Boros for reporting this problem and for testing the improvements).
-+
-+
+. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
-+
+   See readme.field+param.names in the doc folder.
-+
-+
+. IBX SQL Editors will now automatically add double quotes around column names when the database
-+
+   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
-+
-+
+. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
-+
-+
+. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
-+
+   actions.
-+
-+
+. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
-+
+   thanks to Yuriy Kopnin for pointing this out).
-+
-+
+. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
-+
-+
+. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
-+
+   for both fields and parameter setting.
-+
-+
+. Changes to the Select SQL in an IBCustomDataset descendent should now be
-+
+   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
-+
-+
+. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
-+
+    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
-+
-+
+. TIBTable now has a property editor for "MasterFields"
-+
-+
+. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
-+
+    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
-+
-+
+. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
-+
+    of settings is unrecognised. Selecting this radio button has no effect on the settings.

+IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
-+
-+
+. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
-+
-+
+IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
-+
-+
+. In a TIBCustomDataset descendent, a generator now only sets the value when
-+
+   it is null. This allows for alternative user defined setting of the generator
-+
-+
+   Many thanks to Julio Jiménez for this fix
-+
-+
+. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
-+
+   and suggests that the user may have forgotten to install it.
-+
-+
+IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
-+
-+
+. Conditional compilation used to limit registration of TIntegerField to
-+
+   Lazarus versions less than 1.1
-+
-+
+. When a database connection is created, character set is now by default set
-+
+   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
-+
+to 1254.
-+
-+
+IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
+. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
