Re: user defined WM_ question: update

Hi Curt, 
  Thanks for the reply. What I am trying to do is have my application automatically know as soon as any network failure of any kind occurs. This includes anything from someone unplugging the network cable, to a server on the network going down for some reason. I'm using MFC with VC6.0 Professional IDE on WinXP. I'm hoping there is an API available and that I don't have to resort to .NET to accomplish what I want. Any ideas?

I imagine you still need some kind of listener for the "targeted event". Your listener could then use PostMessage(WM_MYEVENT, 0, 0) to tell the UI thread that the event has happened. You haven't provided any specific information about the "targeted event", though -- for all I know, it's got a specialized API to do exactly what you want.

  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.
