[abdulrahmanok]

Welcome brothers,

I have used ".skf" skins and it's working smoothly but when try to Minimize Gui it's stop all program and I can't close it without task manager

this is my source code:
 

#include <GUIConstants.au3>

#include <GUIConstantsEx.au3>
$MyGui = GUICreate("Login", 432, 282, -1, -1, -1, -1)
$DLL = DllOpen("Skin.dll")
DllCall($DLL, "int:cdecl", "InitLicenKeys", "wstr", "SKINCRAFTER", "wstr", "SKINCRAFTER.COM", "wstr", "support@skincrafter.com", "wstr", "DEMOSKINCRAFTERLICENCE")
DllCall($DLL, "int:cdecl", "InitDecoration", "int", 1)
DllCall($DLL, "int:cdecl", "LoadSkinFromFile", "wstr", "Stormy.skf")
DllCall($DLL, "int:cdecl", "ApplySkin")
DllCall($DLL, "int:cdecl", "DecorateAs", "long", $MyGui, "long", 1)
$iIndex_Base = GUICtrlCreateDummy()
$login = GUICtrlCreateButton("Login",67,220,100,30,-1,-1)
$CreateNewACC = GUICtrlCreateButton("Create New ACC",214,220,100,30,-1,-1)
$Delete = GUICtrlCreateButton("Delete",320,40,100,30,-1,-1)
$Edit = GUICtrlCreateButton("Edit",320,85,100,30,-1,-1)
GUISetState(@SW_SHOW, $MyGui)


While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
