drag file content to another application

I need to drag the contents of a file to another application, I have the filepath\name in a string, but I need to drag the contents of that file, not the filename..

most likely I am overlooking something, but I cannot find anything on how to get that done..

what I do now is:

Code:

---

lstRecCase.DoDragDrop(Chr(34) & plyPath & Chr(34), DragDropEffects.Copy)

---

any help much appreciated!

In other words, how do I get .NET to act the same as explorer?
