What is the *.CPL windows?

[semiono]

ShellExecute("rundll32.exe", "shell32.dll,Control_RunDLL desk.cpl,,-1", @SystemDir)

ControlClick("Display Properties","","[CLASS:Button; TEXT:OK; INSTANCE:4]")

Where is the button?

[goldenix]

I think its :

ControlClick("Display Properties", "", "Button3"); The OK button!

OK! Problem found is here - Sleep(500)

ShellExecute("rundll32.exe", "shell32.dll,Control_RunDLL desk.cpl,,-1", @SystemDir)

Sleep(500)

ControlClick("Display Properties", "", "Button3")

        invoke ShellExecute,NULL,NULL,'desk.cpl',',-1',NULL,SW_SHOW
        invoke Sleep,100

        invoke FindWindow,"#32770",NULL
        mov [hWnd],eax
        invoke FindWindowEx,[hWnd],NULL,NULL,button
        mov [cWnd],eax
        invoke SendMessage,[cWnd],BM_CLICK,NULL,NULL
exit:
        invoke ExitProcess,NULL

section '.idata' import data readable writeable
        library kernel32,'KERNEL32.DLL',\
        shell32,'SHELL32.DLL',user32,'USER32.DLL'
        include '%fasm%\api\kernel32.inc'
        include '%fasm%\api\shell32.inc'
        include '%fasm%\api\user32.inc'
