Non-standard UI in C#
.net, c#, notifications, winforms
Solution
Take a look at this third-party WPF NotifyIcon control, I think it does what you want out of the box, hopefully something like this will be part of WPF in the future. I have used this one before for the exact same reason, and it is really good: you can use standard tooltips or "toast" popups, or create your own which could be just like the one in the example you posted if you wanted.
Problem
I'm still learning C#, and I know don't know about WinForms yet but I will very soon. However I want to know how I would create an application which shows a customized notifier, like Growl on a Mac. Here's a mock up: http://img25.imageshack.us/img25/3793/41151387.jpg http://img25.imageshack.us/img25/3793/41151387.jpg Could anyone point me in the right direction? And I know I should learn more about C# before trying this, but I've always liked to peek on complicated stuff.
