TList6.OCX update 6.5.12 04 December 2001
TLTreeVw 1.5.9 30 July 2001

Change	Subject	Description
Addressed	Windows XP Handling	Previous updates of TList 6/Pro displayed warning message to the end-user if an application tried to load the application under an operating system newer than Windows 2000 ( for example XP ). Now a warning message is only displayed to developer that TList 6/Pro is not yet fully tested under Windows XP.
Fix	Multiline text in the cells	Sometimes TList did not draw the text properly if there was a long word followed by a short one and the long word didn't fit into the cell. Under such circumstances the short word could be missed.

TList6.OCX update 6.5.11 17 September 2001
TLTreeVw 1.5.9 30 July 2001

Change	Subject	Description
Fix	Caption	The caption above TList if shown always looked bold.

Fix	Grid.RowCellDef(0)	Grid.RowCellDef(0) should reference column captions row but has erroneously held the row headers since TList 5.0 In order to resolve this without affecting applications built with earlier editions of TList a new Modifications property flag was created With TList Modification including TL_MOD_ROW_CELLDEF = &H400 TList.Grid.RowCellDef(0) references column captions row otherwise this references Row headers column as in past.

TList6.OCX update 6.5.10 30 July 2001
TLTreeVw 1.5.9 30 July 2001

Change	Subject	Description
Enhancement	TDesigner Utility	TDesigner now remembers Window positions, restoring settings from one session to next. Recent files also accessible through File Menu.
Enhancement	3D SHadowed Text Support	TList now supports 3-D text display. This can be set for the entire TList control, or for any column, row, or specific cell. 3-D appearance is achieved using "shadows". A second presentation of the text is drawn offset either above and to left, or below and to right in a secondary shadow color depending on whether text is to appear raised or lowered. Font3D, FontShadowColor, FontShadowSelectedColor properties were added to TListCellDef object. Font3D settings: 0 - Normal Text ( default) 1 - Inset Text 2 - Raised Text FontShadowColor and FontShadowSelectedColor deterimine the color of the shadow for 3d text for normal and selected items.
Enhancement	3D Treelines Support	TList now supports 3-D TreeLine display. This can be set for the entire TList control, or for any column, row, or specific cell. TreeLinesStyle property: new settings TLTREEL_3DINSET_2COLOR = 5, TLTREEL_3DRAISED_2COLOR = 6, TLTREEL_3DINSET_3COLOR = 7, TLTREEL_3DRAISED_3COLOR = 8 - In the above 4 settings TList uses Windows settings to for specification of shadow and highlight color for 3d TreeLines, TLTREEL_3D_USER_COLORS = 9 - In this UserDefined Color setting shadow and highlight color for 3d TreeLines are taken from TreeLinesHighlightColor and TreeLinesShadowColor properties TLTREEL_3D_AUTO_COLORS = 10 - TList automatically calculates TreeLinesHighlightColor and TreeLinesShadowColor based on current TreeLinesColor property. The TreeLinesColor property specifies the base color TreeLinesHighlightColor and TreeLinesShadowColor specify highlight and shadow colors use for 3-D treelines when TreeLinesStyle property is set to TLTREEL_3D_USER_COLORS Either TreeLinesHighlightColor or TreeLinesShadowColor can be set to transparent. This allows drawing 3D TreeLines with 2 colors. If one of this properties is set then TreeLinesStyle property automatically set to TLTREEL_3D_USER_COLORS. TreeLinesHighlightColor and TreeLinesShadowColor return values dependant on TreeLinesStyle property.
Enhancement	The TL65Cnst.h file	Updated TL65Cnst.h file includes all constant definitions for TList. Note constant definitions are actually built into OCX, but this file may be helpful for those working in programming environments which can not read the constants from the OCX
Fix	In-Place Editing	TList1.Grid.Cells(i,1).CheckboxValue and TList1.ItemCheckBoxValue(i) held different values.
Fix	Printing	Column captions of Tree Grid printed incorrectly if the grid was scrolled to right. The grid cells were scrolled in the printed result, but the column titles were not.
Fix		First column of TreeGrid could not be extended if it was minimized by mouse.
Fix	Caption	TList.Caption property did not work. The text does not show in the caption. The problem has appeared since 6.5 version.
Fix	Sorting	TList.ItemGrid(-1) sorting was not working properly.

TList6.OCX update 6.5.9, 31 May 2001

Change	Subject	Description
Enhancement	Help Documentation	The TList help file has been Updated Additional material and examples have been added, and HTML help format has been implemented.
Enhancement	Editing	By default TList converts Variants containing empty value (not initialized) into "one space" string when grid cell in-place editing is started. This can be undesirable for application development. Now, if Modification flag TL_MOD_NEW_EDITING (= &H200) is set then TList converts an empty value Variant into an empty string.
Fix	TList Editing	Memory Leak: There was a memory leak after changing the CellEdit property within the GridCellAfterEditing event. ComboBox: The Drop Down List Combobox could not be edited if CellDef.TextAlignment set to TLTEXTALIGNMENT_NOT_VISIBLE.set to TLTEXTALIGNMENT_NOT_VISIBLE.

TList6.OCX update 6.5.8, 16 May 2001

Change	Subject	Description
Enhancement	Internet Navigation	A new style, TLAUTONAVIGATE_ON_CLICK, has been added to the WebAutoNavigate property. This setting instructs TList to navigate Internet Explorer on a single click rather than a double click.
Enhancement	In-Place Editing	The ScrollHorz property may now be set even during in-place events. The change in scroll position will take effect after in-place editing is completed. New properties (OldSelStart and OldSelLength ) were added to the TListEditingChangeInfo object allowing the reading of prior cursor position and selection during in-place editing. A new flag, TLCOMBO_OPT_EDITAREA_FIT_IN_CELL flag is now supported for the [TListCombobox].Options property. A new flag, TLTEXTBOX_OPT_FULLRECT, is now supported for the [TListTextBox].Options property. It is now possible to copy editing formatting from one TList column or cell to another. For example: Set TList1.Grid.Celldefs(10).CellDef.EditInfo = TList1.Grid.Celldefs(9).CellDef.EditInfo.
Fix	In-Place Editing	A potential memory leak was fixed The cursor was incorrectly moved by TList to the beginning of the text when the text was changed programmatically using the [TListEditingChangeInfo].Value property within the EditingChange event. The value of the .Editable property was not copied when an existing TListEditInfo object was assigned to CellDef.EditInfo property. Set TList1.ItemCell(0).EditInfo _ = TList1.ItemGrid(0).GridCellDef.EditInfo The [TListEditInfo].Editable property was not reset when CellDef.EditInfo property was set to Nothing. AutoResizing did not work correctly when pasting text from clipboard to editing textbox using context menu. TList generated two GridCellEditingChange (or two ItemEditingChange ) events instead of one during in-place editing when end-user replaced some text by hitting a key while some text was selected. The two events had been triggered first in response to deletion of selected text and then for addition of text. Only one event is now triggered because there was only one end-user event and this now allows programmer to return to earlier value if new value is invalid.
Fix	MultiSelection with Virtual Items	TList.Selected (i) property did not return correct value in the case where ( List contained virtual items, AND Redraw = False, AND MultiSelect <>0, AND a Virtual item is selected before turning off the Redraw property.
Fix	RTF Text Under Win2000	TList drew some RTF text incorrectly. This is due to new version riched32.dll included with W2000. riched32.dll version 5 has different behavior than version 4. First: It is impossible to draw transparent background with version 5 of riched32.dll. Second: Text color can be changed for some RTF text at 5 version and can not be changed for the RTF-text at 4 version. As result of these incompatibilities, some RTF text was invisible for selected items under Win2000 or under systems if ver. 5 of riched32.dll is installed. Status - These problem are partly solved: RTF text does not disappear in selected items, but TList can not draw transparent background if riched32.dll version 5 (5.00.2134.1) is installed.

TLIST6.OCX - build 6.5.7, 26 April 2001

Change	Subject	Description
Enhancement	In-Place Editing	It is now possible to capture and validate user actions during editing; New Events: GridCellEditingChange Event, ItemEditingChange Event New Object : TListEditingChangeInfo Object - This object is passed during the ItemEditingChange and GridCellEditingChange events and contains the old and new values, and old and new selection. This feature may be used for instance to watch as the value in a TList editing textbox changes, and optionally to prevent the change, go back to the old value, or put in some new value, (For example to implement type ahead assistance).
Enhancement	ClipBoard Copy	A Modifications property flag, TL_MOD_TLIST6, has been added. If TL_MOD_TLIST6 is set in the Modifications property (TList.Modifications AND TL_MOD_TLIST6 = True) then TList will include data from all columns when copying from a TList Grid or ItemGrid to the clipboard in text format. If this flag is not set, then only the text from the first column will be copied in text format as per older builds. TList always includes all data from all columns in the TList format on the clipboard.
Enhancement	Symbol Font handling	TList now supports wrapping of text with symbol font type under windows 2000.
Fix	ListIndex	TList incorrectly allowed the ListIndex to change in the following situation: 1. user begins editing some item or grid cell, 2. user then clicks on another item this would normally end editing and move the listindex, 3. in AfterEditing event there is code to continue editing:     TList1.ItemEditText(0) = TL_EDITTEXT_CONTINUE Therefore ListIndex should NOT change as user will continue editing the same item or grid cell. Now TList keeps the ListIndex pointing at the item which is still being edited.
Fix	Sorting of TList Editing ComboBox entries	By default TList should NOT sort entries in the drop down list of an editing combobox. This behavior is controlled by the [TListComboBox].Items.Sorting property The Default in 6.5.6 was TLSORT_ASCENDING. The Default is now TLSORT_NONE and items are presented in the order added.
Fix	Overriding Cell Editing Default Styles	There was a problem overriding the editing style for a single grid cell when the default based on the column editing style had been set. This is now corrected. For example: With TList1.Grid     .ColDefs(2).CellDef.EditInfo.Style =TLEDITINFO_CHECKBOX     .Cells(1,2).CellDef.EditInfo.Style = TLEDITINFO_TEXTBOX End WIth

TLIST6.OCX - build 6.0.14, 5 December 2000

Change	Subject	Description
Enhancement	Modifications property	New flag was added.     TList1.Modifications = TList1.Modifications Or &H100 TList won't change the ListIndex and select the last item in the tree in case of clicking over the empty space below tree when either single or multi selection mode is activated.

TLTreeVw.OCX - build 1.0.17, 17 November 2000

Change	Subject	Description
Fix	TList6.OCX - Memory Leaks	Memory leak was found and corrected: Calling ItemURL property causes memory leak.
Fix	TDesigner application	User can not chnage the string type value on Values tab of Item Properties dialog.
Fix	TList6.OCX	Some changes were made in order to meet CVC-certification requirements.
Fix	Spelling in the error message	"TListTreeView control doesn't work with installed version of TList control.\n" "Please install correct version of TList6 control " "and specify correct license information.\n" "If you have any licensing problems please contact " "to Bennet-Tec Information Systems."
Fix	Drawing internal lines of the grid	Following code makes TList to draw undesired horizontal grid lines:     TList1.AddItem "Root" TList1.AddItem "Item1", 0     TList1.AddItem "Item2", 1     TList1.Grid.Cols = 3     TList1.Grid.BorderStyle = &H7     TList1.Grid.GridLinesStyle = TLGRIDLINES_NONE
Fix	TList6.OCX	Under some curcumstances TList incorrectly draws with Redraw property = FALSE
Fix	Plus/minus signs problem	If user specifies ViewStyleEx=1 (Display Plus/Minus image for all items) and tries to disable displaying plus/minus signs for some of the items using following code:     TList1.ItemPMPicType(index) = 3 '-don't show any p/m picture TList just ignores drawing plus/minus signs but doesn't replace the empty space from the signs with the tree lines.
Fix	LevelDefs and sorting problem	Following code:     TList1.LevelDefs(1).Sorted = True     TList1.Clear TList1.AddItem "Root1"     TList1.AddItem "bbb", 0     TList1.AddItem "aaa", 0     TList1.LevelDefs(1).Sorted = True Second call of the Sorted property does not resort level after modifying the tree.
Fix	VisualRoot problem	The problem takes place when user sets the visual root to the item that is collapsed.
Fix	OLE object reference problems	If user saves the reference to the OLE CellDef object and delete some attribute from this cell, this reference can become invalid and can not be used anymore. This happens only if there is only one attribute for the cell (like background color in this sample) Following code shows the potential problem:     Dim objCell As TlistCellDef     Set objCell = TList1.Grid.Cells(1, 2).CellDef objCell.BackColor = 1     ' - after this call the objCell object became disconnected from the tree and following call doesn't change the color of the cell of the grid objCell.BackColor = RGB(0, 0, 255)
Fix	Saving and loading back files containing object references	If some TList items have a value pointing to the OLE object that can not be saved properly in the TLIst file (because such OLE objects don't support correspondent OLE interface) TList can not load the file that contains such items back properly. Following code method LoadData return error "1 - Read File Error":     TList1.AddItem "Root"     TList1.ItemValues(0, "object").Value = New Collection     TList1.SaveData "c:\temp\tlt.tlt"     TList1.LoadData "c:\temp\tlt.tlt" Now TList will just ignore OLE objects that can't be loaded.
Fix	Focus transferring problem for TListTreeView control	Sometimes keyboard doesn't work properly when user changes the focus via mouse (instead of using TAB key). It happens only if KeyPreview on the form is set to TRUE.

Fix	TList - Wordwrap with RTF	TList did not display a very long last word in an RTF formatted cell if Multiline property is set to false. Note - RTF-formatted single-line text width is limited by width of screen (in pixels). This limitation may be addressed through the WidthOfText Property.
Fix	TList - MouseWheel	TList failed if end-user used MouseWheel to try scrolling empty TList (without items).
Fix	TList - RTF Editing	TList failed after end-user hitting Escape Key to cancel editing of RTF formatted cell in AutoEdit mode (EditingMode <>0)
Fix	TList.OCX / TLTreeVw.OCX - AutoDrag & LevelDef sorting	In rare situations using AutoDragDrop and LevelDef sorting, some items on sorted level became unsorted after a DragDrop operation.
Fix	TList.OCX - LevelDefs	The Indentation property of TLLevelDefs object could not be read in some situations:     Dim LDefs As TlistLevelDefs     Dim LDef As TlistLevelDef     Dim vTmp As Variant     TList1.LevelDefs(5).PictureOpen = Picture1.Picture     Set LDefs = TList1.LevelDefs     For Each LDef In Ldefs         vTmp = LDef.Indentation '- TList failed on this line     Next

Change	Subject	Description
Enhancement	In Place Editing	TList starts automatic in-place editing for tree items only if the TL_EDITMODE_TREE_ITEMS flag is set in the EditingMode property. (Note: even if tree is displayed inside the first column of TreeGrid)
Enhancement	TListTreeView - Getting Node References	Three new methods were added: NodeFromItem (ByVal TListItemIndex As Long) As Node NodeFromGridCell (ByVal GCellObj As TListGridCell) As Node NodeFromTListNode (ByVal TLNodeObj As TListNode) As Node These methods return a TListTreeView node object, or an empty object (NULL) if there is no corresponding TreeView node, for instance if GridCell is TreeGrid Column Title cell. These methods simplify converting a TList ItemIndex, TListNode or TListGridCell reference to a TreeView Node Example: '-getting reference to Node object using reference to TListGridCell object Sub TreeView1_TList_GridCellClick(ByVal GridCell As TlistGridCell, _ ByVal Button As Integer)     Dim NodeObj As Node     Set NodeObj = TreeView1.NodeFromGridCell( GridCell )     Debug.Print "TreeView Node key = " & NodeObj.Key End Sub
