RichTextBox and dodragdrop

[Lance Johnson]

I seem to be having troubles implementing dragdrop on a richtextbox. I seem
to have been able to get the dropping part working fine when coming from an
external application. It's the dragging part.

It does seem to drag, but the icon always stays as None and I have no idea
why. I can see in my code on the drag enter for entering the other control
that it's set. However, the icon never changes and if I drop it, the
DragDrop event never fires. Am I missing something or do I need to
implement my own code for doing the drag operation?

You need to copy the dragged data to the Clipboard in an appropriate
format. I have just re-installed the OS on this PC so don't have access
to .NET at the moment but have a look at the help for Clipboard.SetData
(from memory).

If nobody else chimes in and you still have issues come back, I have a
couple of routines for setting the Clipboard in DROPFILES format and
the format Explorer expects to create shortcuts if that's of interest.

I will have .NET installed soon,none of my utilities work without it!
