GNET php coding / Alt-Tab

I found a solution :)

user32.decls
.lib "user32.dll"
api_GetActiveWindow% () : "GetActiveWindow"

Function DetectMinimise()
	window=api_GetActiveWindow()
	If window<>myWindow
		If Not minimised
			minimised=True
		EndIf
	Else
		If minimised
			minimised=0
			FreeImage menu
			Delay 250
			Graphics 640,480,0,2
			menu=LoadImage("ui\menu.jpg")
			For b=1 To 6
				button(b)=LoadImage("ui\button"+b+".tga")
			Next
		EndIf
	EndIf
End Function

Now I just need to make it store and restore the window position, which i've not quite managed yet.
