Delete zero column.

[rasim 21]

Hi! How correctly delete zero column? I see in the help file this remark:

If you must delete column zero, insert a zero length dummy

column zero, and delete column one and above

But i don`t know how?

I`m seem i found a solution:

Func DelColumn($cIndex)
    If $cIndex = 0 Then
        _GUICtrlListView_InsertColumn($hListView, 0, 0)
        _GUICtrlListView_DeleteColumn($hListView, $cIndex)
    Else
        _GUICtrlListView_DeleteColumn($hListView, $cIndex)
        _GUICtrlListView_InsertColumn($hListView, $cIndex, "SubItems")
    EndIf
EndFunc

No Items not deleted, but set invisible.

    EndIf

No Items not deleted, but set invisible.

That's not doing what you quoted in your first post, and also the third parameter should be text not zero so maybe this will work

Func DelColumn($cIndex)
    If $cIndex = 0 Then
        _GUICtrlListView_InsertColumn($hListView, 0, '');<---'' was 0
        _GUICtrlListView_DeleteColumn($hListView, 1);<----1 was 0
    Else
        _GUICtrlListView_DeleteColumn($hListView, $cIndex)
        _GUICtrlListView_InsertColumn($hListView, $cIndex, "SubItems")
    EndIf
EndFunc[

Just delete column zero, I believe that documentation is wrong.
