What is the proper method to use _GUICtrlListView_DeleteItem :(

[Digisoul]

Hello there,

I am trying to delete the selected items from the list, but its left some items.

for example i select 3 random indices from the ListView and save them in array $sel_index

$sel_index[0]=0
$sel_index[1]=2
$sel_index[2]=5

now its successfully delete the item at 0 index,but its failed for all other indices, because the item index 2 become 1 and item index 5 become 4.

here is my code for deleting items

_GUICtrlListView_BeginUpdate($Lhwnd)
For $d = 0 to UBound($sel_index)-1
    $res = _GUICtrlListView_DeleteItem($Lhwnd,$sel_index[$d])
    ConsoleWrite("-"&@TAB&"Selected Index :"&$sel_index[$d]&" Result:"&$res&@CRLF)
Next
_GUICtrlListView_EndUpdate($Lhwnd)

Please tell me how can i handle this problem.

Thanks in advance for your help.

If the item indexes are in ascending order in your array then simply change the direction of walking through the array. If they are in random order then first sort the array.

For $d = UBound($sel_index)-1 to 0 step -1

should do the trick. Edited September 16, 2009 by water

When you start deleting the ListView from the highest to the lowest index it works fine. See this example:

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <WindowsConstants.au3>

Global $GUI
Global $sel_index[3] = [2,5,7]

$GUI = GUICreate("(UDF Created) ListView Create", 400, 300)
$hListView = _GUICtrlListView_Create($GUI, "", 2, 2, 394, 268)
_GUICtrlListView_InsertColumn($hListView, 0, "Column 1", 100)
_GUICtrlListView_AddItem($hListView, "Item 0")
_GUICtrlListView_AddItem($hListView, "Item 1")
_GUICtrlListView_AddItem($hListView, "Item 2")
_GUICtrlListView_AddItem($hListView, "Item 3")
_GUICtrlListView_AddItem($hListView, "Item 4")
_GUICtrlListView_AddItem($hListView, "Item 5")
_GUICtrlListView_AddItem($hListView, "Item 6")
_GUICtrlListView_AddItem($hListView, "Item 7")
_GUICtrlListView_AddItem($hListView, "Item 8")
_GUICtrlListView_AddItem($hListView, "Item 9")
_GUICtrlListView_AddItem($hListView, "Item 10")
_GUICtrlListView_AddItem($hListView, "Item 11")
_GUICtrlListView_AddItem($hListView, "Item 12")
GUISetState()
MsgBox(0,"","Deleting Item 2,5 and 7")

_GUICtrlListView_BeginUpdate($hListView)
For $d = UBound($sel_index)-1 To 0 Step -1
    $res = _GUICtrlListView_DeleteItem($hListView,$sel_index[$d])
    ConsoleWrite("-"&@TAB&"Selected Index :"&$sel_index[$d]&" Result:"&$res&@CRLF)
Next
_GUICtrlListView_EndUpdate($hListView)
GUISetState()
MsgBox(0,"","Deleted Item 2,5 and 7")
GUIDelete()

Try this : _GUICtrlListView_DeleteItemsSelected(GUICtrlGetHandle($List))

That will delete the selected.
