Per Erik Strandberg: Csharp Tool Tip Test

I've used tool tips (see English Wikipedia on tooltips: [1]) many times, but never written a minimal test for it - so here is one :) See also Csharp Override Tool Tip Test, Csharp Data Grid View And Tool Tip Test and Csharp Custom Tool Tip.

The important part is a System.Windows.Forms.ToolTip and configuring it on a specific component with this.tt.SetToolTip(this.btnExit, "Press to exit.");

By adding this.tt.IsBalloon = true; the style of the tool tip is more like a ballon.

Two screenshots here:
