[omniORB] How can I get control after all orb->run()

[David Hyde]

In my Win32 program I have done the following:

	MSG msg;
	while (g_bRun && GetMessage(&msg, NULL, 0, 0))  
	{
		DispatchMessage(&msg);

		if (pORB->work_pending())
			pORB->perform_work();
	}

	pORB->shutdown(0);

	pORB->destroy();
	CORBA::release(pORB);

maybe you can do something with this.  It would probably mean that you'd
have to put the wait for input routine into a seperate thread and set the
global g_bRun flag when the relevant input has been detected.

Hope this helps

David
