how to stop images flashing as they show and hide

[Arfur9]

I'm trying to do a hidden objects game and I have a problem were for a split second as the image changes I get a white area as the image hides/shows, is there anyway to stop this?

this is the code I'm messing with

expandcollapse popup

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <Sound.au3>
Opt("GUIOnEventMode", 1)
$Form1 = GUICreate("Form1", 800, 600, -1, -1)
$img="Backgroundalley.jpg"
$door ="door.jpg"
$dooropen = "dooropen.jpg"
$Pic1 = GUICtrlCreatePic($img, 0, 0, 800, 600)
GUICtrlSetState($Pic1, $GUI_DISABLE)
Local $aSound = _SoundOpen("machineClose.mp3")
$Pic3 = GUICtrlCreatePic($dooropen, 142, 6, 299, 540)
GUICtrlSetTip(-1, "Door")
GUICtrlSetOnEvent(-1, "Pic2Click")
GUICtrlSetState($Pic3,$GUI_HIDE)
$Pic2 = GUICtrlCreatePic($door, 142, 6, 299, 540)
GUICtrlSetTip(-1, "Door")
GUICtrlSetOnEvent(-1, "Pic1Click")
GUISetState(@SW_SHOW)
GUISetOnEvent($GUI_EVENT_CLOSE, "mainClose")
While 1
Sleep(100)
WEnd
Func mainClose()
$ExitDialog = MsgBox(36, "Are You Sure?", "Are you sure you want to exit?")
If $ExitDialog = 6 Then

Exit
Else
Return
EndIf
EndFunc ;==>mainClose

Func Pic1Click()
Sleep( 111)
GUICtrlSetState($Pic2, $GUI_HIDE)
GUICtrlSetState($Pic3, $GUI_SHOW)
;_SoundPlay($aSound, 1)
Return
EndFunc
Func Pic2Click()
GUICtrlSetState($Pic3, $GUI_HIDE)
Sleep( 1)
GUICtrlSetState($Pic2, $GUI_SHOW)
;_SoundPlay($aSound, 1)
Return
EndFunc

I've attached the images and file

In your pic1click function try doing the show command before the hide... In your second function you have a sleep(). Even tho you've put "1" there, it's actually going to sleep for 1000.

Hope this helps.

When you create your GUI, try using the Windows style $WS_EX_COMPOSITED. See if that stops the flickering.
