receiving registerd message

[Don Dickinson]

i have a console app that needs to monitor for a windows message (created with RegisterWindowMessageand received in response to BroadcastSystemMessage). can anyone tell me how to intercept this message from a pbcc app?

FUNCTION PBMAIN () ...

   CreateWindowEx   ..     (NOT %WS_VISIBLE IS FINE) 
   ShowWindow 
   MessageLoop 


FUNCTION myWndProc 

  [COLOR="Red"]STATIC [/COLOR]TheMessage AS LONG 

   SELECT CASE AS LONG wMSg
        CASE %WM__CREATE
           TheMessage =  RegisterWindowMessage (....) 

        CASE TheMessage
               do something, because you just received the registered message

Or create a GRAPHICS WINDOW and subclass it. It is hidden by default.

Related: Actually does RegisterWindowmessage and processes same:

Add a 'Favorite Files' menu to your application 10-25-07

That does it in a dialog procedure, but the principle is the same. (DragListMsg)

I know you know this, Don, but newer members may not...

Given this is a PB/CC program, I am guessing that program is actually "doing something else" whilst waiting for this message.

Therefore, you probably want to run the either the message loop or the 'something else' in a separate thread of execution.

You could build on GUI + Worker Thread + Abort Demo 11-24-07, launching the "something else" as a separate thread of execution on WM_CREATE .

When "something else" is done, it can post a message (WM_CLOSE comes to mind) back to the same (invisible?) window, and on WM_CLOSE in the WndProc you can Unregister the message (thou shalt clean up) before allowing the default processing, which is to destroy the window.
