    how to obtain messages that have been posted/sent into a control?

    SPY++ only shows messages that the control has sent out, not messages that it receives

    help file from spy++
    P The message was posted to the queue with the PostMessage function. No information is available concerning the ultimate disposition of the message.
    S The message was sent with the SendMessage function. This means that the sender doesn’t regain control until the receiver processes and returns the message. The receiver can, therefore, pass a return value back to the sender.
    s The message was sent, but security prevents access to the return value.
    R Each ‘S’ line has a corresponding ‘R’ (return) line that lists the message return value. Sometimes message calls are nested, which means that one message handler sends another message.

    Please keep windows specific questions on the windows board.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    A control doesn't send a message, code sends a message. If you have a look at the SendMessage function, you'll note that there is no from argument.
