Emulating a mouseclick using PostMessage

I am using python's win32 module to create a simple click() method, which should emulate a mouse click, but unfortunately my approach is not working.

def click(x, y):
    hWnd = win32gui.FindWindow(None, "SomeWindowTitle")
    lParam = win32api.MAKELONG(x, y)

    win32gui.PostMessage(hWnd, WM_LBUTTONDOWN, MK_LBUTTON, lParam);
    win32gui.PostMessage(hWnd, WM_LBUTTONUP, MK_LBUTTON, lParam);

...
timer = Timer(30, click, [x, y])
timer.start()

I am thankful for every hint!

I got it working now.. The above code is working well, the only thing I was not aware of was that I was getting my cursor position from win32api.GetCursorPos() in screen coordinates, but win32gui.PostMessage() needed the relative coordinates of the hWnd. Simply converting it with ScreenToClient() did the trick.
