I am trying to send a message of WM_CHAR from an out of process application directly to Firefox or Internet Explorer. I've got the handle to the Firefox window. The FF web page is setup to Yahoo Mail and I would like to populate the user name and password via SendMessage or PostMessage. Does FF process WM_CHAR messages and if not what would be other means of accomplishing the same. I have tried with no luck in using WM_CHAR with both SendMessage and PostMessage. It does not work. The handle is correct because I can close out Firefox b sending a WM_CLOSE message to it.
Thanks in advance
