I have created an application that runs in the taskbar. When a user clicks the application it pops up etc. What I would like is similar functionality to that in MSN when one of my friends logs in. Apparently this is know as a toast popup? I basically want something to popup from every 20 minutes toast style fom the application in the taskbar. My existing application is winforms based written in C# with .net 3.5 Cheers
