Shoutbox

Hmm... I thought of detecting when it's an unknown type and then check the message:
If it is a file cancelled/completed then change the counter according to it.
I don't know the exact message, try to play with it in the trace to see.
Just a thought: if the WLM client is English/non-English, you will probably need to check with a different message.
Or if it is the error YOU get then do it according to your client (not good if you plan to share it, you will need to get all languages messages).

I don't know about the bool var (true/false), u should ask someone who is much more expirienced with this.
