Re: ATL COM server for System Tray Icon
The source code got mangled, but I spotted a call to Sleep in there.
This is a big no-no for a single-threaded apartment (which you joined
when calling CoInitialize). You need to run a message pump instead - see
GetMessage, DispatchMessage (yes, console applications can have a
message pump).

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925

I am trying to get a system tray icon to animate from a console
application. I am using the example from codeproject:
http://www.codeproject.com/atl/system_tray.asp?forumid=4142&select=1759154&df=100&msg=1759154
The example works fine from the user app supplied in the source code.
Since my app is a console project, I attempted to build a very
rudimentary
console application that calls directly into the interface:
// systemtraydemoclient.cpp : Defines the entry point for the console
application.
//
#include <iostream>
#define INITGUID
#include <objbase.h>
#include "SystemTrayDemo.h"

icon appears on the system tray and the message popup works
withmouseover, but the animation does not work.With regards to
launching this COM server from a console app, is this a sideeffect? I
would think the animation would work regardless of whether Icalled
the COM server from a windowed app or a console app.Thanks,Albert
