GUICtrlSetState() seems not to work with Handles [solved]

[KaFu 193]

HiHo Forum,

i have a problem with the GUICtrlSetState() function. If i try to hide a Treeview created with _GUICtrlTreeView_Create() the function won't work. Reason is, that _GUICtrlTreeView_Create() returns a handle and not a control id. I've adjusted the example from the Help-File accordingly.

Is this a Bug? And has anyone a workaround for me?

GUICtrlSetState() works with control ID's only

#Include <WinAPI.au3>
_WinAPI_ShowWindow(GUICtrlGetHandle($treeview), @SW_HIDE)

Thanks for the reply and work-around...
