Drag-drop: How to draw a "ghost" control that represents data being dragged?

I have searched a lot and the nearest thing I have found is this. The question is exactly about what I want to code, but there's only one vague answer. Searched code.google.com for Gi开发者_运维技巧veFeedback implementations, but none about what I want. Any idea, please?

Assuming this is C# / Windows Forms, if you use the built-in API for drag & drop, then you get a "dragging" mouse cursor for free. That is really the easiest solution.
