#555 closed Bug (Works For Me)

bug in _GUICtrlListView UDF

Reported by: anonymous Owned by: Gary
Milestone: Component: Standard UDFs
Version: Severity: None
Keywords: Cc:


_GUICtrlListView_SetItemDropHilited didnt work properly, so we tried to find out why.

_GUICtrlListView_SetItemState is buggy. in UDF Doc it says:

; $iState - Item state to be changed
; $iStateMask - Bits that determine whether state is active or inactive

those Values are used for creating a dll struct. the problem now is:

StateMask is the Item state to be changed,
State are the Bits determining the state is activ or not (

this version should work, but I just tested _GUICtrlListView_SetItemDropHilited , which seems to work fine now

I think, some other Functions have to be changed then, too :)
_GUICtrlListView_SetItemDropHilited is correct, but it didn't work with the old _GUICtrlListView_SetItemState, with the corrected one, the DropHilite can be deleted again.

Show some code where the old doesn't work. Not seeing any problem with the current code in the include.
