[RESOLVED] Click a button on external program

I want to click a button on an external program from code. The button doesn't have any shortcut assigned to it, so I can't use sendkeys.

I managed to find the hwnd of the button, but I don't know how to click it. Any ideas?

You can use findwindow and findwindowex to get the handles then use BM_CLICK with sendmessage to click the button.

Thanks Jmacp, BM_CLICK was just what I was looking for.
