Hi Anuradha,
When you create an ATL COM exe server ( I am guessing you are
creating a NT service), ATL COM generates the following code for you..

inline void CServiceModule::Handler(DWORD dwOpcode)
{
switch (dwOpcode)
   {
case SERVICE_CONTROL_STOP:
   SetServiceStatus(SERVICE_STOP_PENDING);
      PostThreadMessage(dwThreadID, WM_QUIT, 0, 0);
      break;
   case SERVICE_CONTROL_PAUSE:
      break;
   case SERVICE_CONTROL_CONTINUE:
      break;
   case SERVICE_CONTROL_INTERROGATE:
      break;
   case SERVICE_CONTROL_SHUTDOWN:
      break;
   default:
      LogEvent(_T("Bad service request"));
   }
}

In the SERVICE_CONTROL_SHUTDOWN case , you can send messages to the clients.
Unless I am missing some points in your questions, I think this should
work..

hi Kala,

Thanks for replying.. I have the folowing doubts.
Would be grateful for any guidance.

I thought I could fire a Disconnect event (which I
normally fire when any client disconnects.. to inform
all other clients that this client has disconnected)
The problem is that I dunno where I would get the
shutdown event from windows...
Is there a way where I could fire this event
'Fire_OnDisconnect()' before the class object is
destroyed...

I have a ATL COM exe server (singleton).
In the winmain, shouldn't a loop like the following
work ? ->
while (GetMessage(&msg, 0, 0, 0))
{
if (msg.message == WM_QUERYENDSESSION) //or WM_CLOSE
   MessageBox(NULL, "gotcha", "ChatServer", MB_OK);
DispatchMessage(&msg);
}
Please correct me if I am wrong ..

Regards,
Anu.
