Finding the problem with this code...

[namedrisk]

Hi,

i was trying something basic with this code but it does not seem to work and i would like to know if any experienced people with AutoIT and user32.dll could help me out...

i found this code in this forums and was trying to send "o down and up" to notepad basic getting it is handle using the window title.

I DO realise that there is SEND and CONTROLSEND but that does not solve my problem it has to be with user32.dll

Thanks for any help.

#include <WindowsConstants.au3>

Local $user32 = DllOpen("user32.dll")
Global $hwnd = WinGetHandle("Notepad - Edit1")

KeySend("o", "down")
Sleep(2000)
KeySend("o", "up")
DllClose($user32)

; send single keyboard event to non active window
; event = pressed, down, up
; kdown = key down delay
