Strange behaviour while using wrong GUI parameter

[Xenobiologist]

Hi,

I tested this script and my Windows hung up after I clicked the trayicon and closed the script in Scite.

Sometimes the edit pane is visible, sometimes not. If it is, the behaviour described above happens. I know this is not a "bug", cause I assume that I do use the GuiCreate Func wrong, but I nevertheless wanted to share the info.

#include <EditConstants.au3>
#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
$n_studi_gui = GUICreate("Nach Studienzeit", 950, 720, @DesktopWidth / 2 - 475, @DesktopHeight / 2 - 360, $WS_border, Default)
GUICtrlCreatePic(@ScriptDir & "\Bilder\Nach.jpg", -1, -1, 950, 720, $ws_disabled)
$n_studi_zurueck = GUICtrlCreateButton("zurück", 800, 600, 140, 80, 0)
$n_studi_button1 = GUICtrlCreateButton("Tätigkeiten", 50, 25, 175, 50)
$n_studi_button2 = GUICtrlCreateButton("Verdienst", 50, 75, 175, 50)
$n_studi_button3 = GUICtrlCreateButton("Weiterbildungsmöglichkeiten", 50, 125, 175, 50)
$edit = GUICreate(400, 10, 500, 400, $WS_POPUP, Default, $n_studi_gui)
$n_studi_edit = GUICtrlCreateEdit('', 500, 10, 400, 500, Default);BitOR($WS_HSCROLL, $WS_VSCROLL, $ES_READONLY))
GUICtrlSetFont(-1, 10, "", "", "Comicsan MS")
GUISetState(@SW_SHOW, $n_studi_gui)
GUISetState(@SW_SHOW, $edit)

While 1
	$msg = GUIGetMsg()
	If $msg = $GUI_EVENT_CLOSE Then ExitLoop
WEnd
GUIDelete()

It's not strange. You're passing an HWND as the extended style. Since the HWND changes from run to run, you pass a different value every time. Since the extended style is just bitwise flags, you're passing a different combination each time. That's why the results are unpredictable.

Yes, but why does Windows hang after passing a handle as style?

Does it matter? It's bad input and bad things happen. I'm not interested in debugging why Windows behaves the way it does with garbage input like that.
