_GUIImageList_BeginDrag.au3 - example in helpfile

[Zedna]

"C:\Program Files\AutoIt3\Beta\Examples\Helpfile\_guiimagelist_begindrag.au3"

1) on my WINXP SP2 Czech it doesn't show any image at cursor position while draging listview items (also cursor doesn't change to draging cursor)

2) there is bug: after draging is set bad item text at target (dropped) position --> only first letter is shown in first column of listview

3) I suggest this change/correction to show implemented also "autoscrolling" while draging:

...
;~ 	$hListView = _GUICtrlListView_Create($main_GUI, "Entry Name|Category", 5, 75, 220, 280, -1, BitOR($WS_EX_CLIENTEDGE, $WS_EX_STATICEDGE))
	$hListView = _GUICtrlListView_Create($main_GUI, "Entry Name|Category", 5, 75, 220, 180, -1, BitOR($WS_EX_CLIENTEDGE, $WS_EX_STATICEDGE))
;~ 	$LV_Height = 280 - 75 ; --> this was wrong in original
	$LV_Height = 180
...

I found this bug:

Func _LVInsertItem($i_FromItem, $i_ToItem)
	Local $item_state, $i_newIndex
	Local $struct_LVITEM = DllStructCreate($tagLVITEM)
	Local $struct_String = DllStructCreate("char Buffer[4096]")
	Local $sBuffer_pointer = DllStructGetPtr($struct_String)
...

There should be wchar instead of char:

	Local $struct_String = DllStructCreate("wchar Buffer[4096]")

I think this kind of ANSI/Unicode bug probably will be also in another standard UDFs.

The same applies also to another function:

Func _LVCopyItem($i_FromItem, $i_ToItem, $i_SubItem = 0)
	Local $struct_LVITEM = DllStructCreate($tagLVITEM)
	Local $struct_String = DllStructCreate("char Buffer[4096]")
	Local $sBuffer_pointer = DllStructGetPtr($struct_String)

Purpose of that change is to have vertical scrollbar visible in listview (set less hight of listview) to be able to test implemented "autoscrolling" while draging functionality. BTW: That autoscrolling works very nice.
