Disable / Enable Minimization

[YellowLab]

Doing a search I found this OLD (2006) topic:

http://www.autoitscript.com/forum/index.php?showtopic=35748

This is exactly what I am seeing - using version 3.2.12 and this code:

$hMain=GuiCreate("Main",100,100,100,100)
$hButton = GUICtrlCreateButton("Open",0,0,50,20)

$hSecond=GUICreate("Second",50,50,125,125)
$hSButton=GUICtrlCreateButton("Close",0,0,50,20)

GUISetState(@SW_SHOW,$hMain)

While 1
    $nMSG = GUIGetMsg()
    Switch $nMSG
        Case -3
            Exit
        Case $hButton
            GUISetState(@SW_DISABLE,$hMain)
            GUISetState(@SW_SHOW,$hSecond)
        Case $hSButton
            GUISetState(@SW_HIDE,$hSecond)
            GUISetState(@SW_ENABLE,$hMain)
    EndSwitch
WEnd

modifying it to

Case $hSButton

GUISetState(@SW_HIDE,$hSecond)

GUISetState(@SW_ENABLE,$hMain)

GUISetState(@SW_RESTORE,$hMain)

causes the GUI to flicker - not so bad in this small example, but very noticeable in larger GUI's. Any ideas on how to fix it?

Thanks,

Bob

Look here at concept (unfortunatelly not working for me):

#include <GUIConstants.au3>

;~ Const $SC_CLOSE = 0xF060
Const $MF_BYCOMMAND = 0x0
;~ Const $MF_GRAYED = 0x1
;~ Const $WM_SYSCOMMAND = 0x0112

$gui = GuiCreate("Catch the Minimize Click", 300, 100)
GUISetState()
GUIRegisterMsg($WM_SYSCOMMAND, "On_WM_SYSCOMMAND")

$hMenu = DllCall("user32.dll", "hwnd", "GetSystemMenu", "hwnd", $gui, "int", 0)
;~ DllCall("user32.dll","hwnd","DeleteMenu", "hwnd", $hMenu[0], "int",$SC_MINIMIZE, "int", $MF_BYCOMMAND)
DllCall("user32.dll","hwnd","EnableMenuItem", "hwnd", $hMenu[0], "int",$SC_MINIMIZE, "int", BitOr($MF_BYCOMMAND,$MF_GRAYED))

While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            Exit
    EndSelect
WEnd

; to disable minimize hotkeys
Func On_WM_SYSCOMMAND($hWnd, $Msg, $wParam, $lParam)
    If BitAND($wParam, 0xFFF0) = $SC_MINIMIZE Then Return
EndFunc

Strange... I don't see any flickering

Okay, so I figured it out - not so difficult really:

$hMain=GuiCreate("Main",100,100,100,100)
$hButton = GUICtrlCreateButton("Open",0,0,50,20)

$hSecond=GUICreate("Second",50,50,125,125)
$hSButton=GUICtrlCreateButton("Close",0,0,50,20)

GUISetState(@SW_SHOW,$hMain)

While 1
    $nMSG = GUIGetMsg()
    Switch $nMSG
        Case -3
            Exit
        Case $hButton
            GUISetState(@SW_DISABLE,$hMain)
            GUISetState(@SW_SHOW,$hSecond)
        Case $hSButton
            GUISetState(@SW_ENABLE,$hMain)
            GUISetState(@SW_HIDE,$hSecond)
    EndSwitch
WEnd

The first window must be enabled before the second window is hidden. Doing it this way makes everything good.
