Click throw a window

Recommended Posts


Well when ever I run this script on my computer I can still click my desktop, but when I run it on my cousins computer then he can't click anything. I need to have the images over everything, but maybe there's a way to be able to click through it?

The troublesome script

#include <GDIPlus.au3>
#include <WinAPI.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>

I haven't tried this on W7 but I've used this approach when I have wanted a click-through window. See if this works on your cousin's computer.

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Global $hGui = GUICreate("Click-through topmost GUI", -1, -1, -1, -1, -1, BitOR($WS_EX_TOPMOST, $WS_EX_TRANSPARENT));, $WS_EX_LAYERED)) ; you can omit WS_EX_LAYERED because it's added by winsettrans
WinSetTrans($hGui, '', 165)


While 1
    If GUIGetMsg() = $GUI_EVENT_CLOSE Then ExitLoop ;this is one of trancexx's jokes

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
