Re: user defined WM_ question: update

  OK, I got the WM_USER code to work, now is it possible to get the event handler to fire automatically? I really don't want to use polling, even if it is on a separate thread. Currently I have the WM_USER event being triggered through SendMessage(WM_MYEVENT,0,0); inside an OnClicked( ) handler attached to a UI button. Although this is working in my test app, I want the event to be fired automatically by the OS when the targeted event occurs.

  Any ideas? Thanks guys.

Hi All,
 I have a function that I need to fire when a specific event occurs. The event that I need to trap is a network failure of any kind. I have the code that detects when a network failure has occurred but at present the function is inside a command line interface program and I want to transfer that function into an MFC app and have the function activated by a WM_ event. My question is, is it possible to get the user defined WM_ to fire automatically, or does the user have to send the event message manually, such as by clicking a UI button or something?

Also, I considered using WM_USER to define the custom WM_ message, but my research indicates that WM_APP is the preferred method for defining a custom message. Any thoughts on this? Even better, any concrete examples?  ; )   I've looked all over the net and through my library of
 books with no luck. It's a shame a person can't loose weight by running in circles, because I seem to be getting nowhere fast. Thanks guys.
