Disable Drag&Drop of files in Richtextbox in .NET

Question

I use a .NET richtextbox and I want to have the EnableAutoDragDrop property set to True. This allows user to drag&drop text, rtf and images around etc.

However, I need to process files dropped into the richtextbox myself - I do not want them to be embedded as OLE objects when they are dropped.

How can I overcome this? Is there any way to delete embedded files from richtextbox?

(I've found API DragAcceptFiles which doesn't work for some reason.)

Thanks!

Try handling the DragDrop event.

You may try this MSDN article. If you do not wish to lock the file,you can use IO stream. Google it and It will sole your problem.
