I really like the MSN notification popup. Basically the popup you see when you receive a new email etc. I'd like to put timers and set times so I, for instance, get a popup at 2PM saying "Don't forget..." I know I could make my own notification bubble but I'd prefer the WLM one.
Thanks
The answers in this question might help you: Is it possible to programmatically talk to MSN messenger / Live messenger?. Looks like there might be libraries that might allow you to make the api calls you want.
Failing finding a way to talk to WLM directly, you may want to consider making your own notification bubble and make it look identical to the one in WLM.
