   You seem to be right: "Sent by a common control to its parent
window when an event has occurred in the control or the control
requires some kind of information." (MSDN)

   I'm not sure I've ever used that message. The only code I
can think of where it appears is with a RichEdit. I have to
watch for WM_NOTIFY in the subclass of the parent window
in order to get the EN_SELCHANGE RichEdit event, to know
when the selection has changed. The RichEdit sends the
WM_NOTIFY to the parent window, as MS says.

    Since you haven't explained exactly what you're trying
to accomplish, this is all academic. Without context and
details it sounds like you're trying to send messages within
your own program, like a son writing a letter to his mother
and sending it through the mail, when you could use something
like an event or function, since you're writing both the parent
window and the child window.
