    reading editbox contents from a different program

    I need to read the contents of an editbox (or possibly a richedit box) from another program, and I'm not at all sure how to do this. GetWindowText() works when called on editboxes from my own program, but it just returns an empty string when I've tried it on editboxes from other programs. Does anyone know how I could do this?

    Use SendMessageTimeout to send various edit control messages to the target control as discussed towards the end of this thread.

    This is kind of a stupid question, but do you know what message I might use for this, or even better how I could get a list of the messages an edit box can accept?

    The messages of interest are discussed in the thread I mentioned in my previous post (EM_GETLINE, EM_GETLINECOUNT, for example). You can get a comprehensive description of edit controls, their messages, etc. from this page on msdn.
