Hi all
I've written some code for files selected in explorer to be dragged and dropped in to my application (Not Rocket Science).
Q. How do I access the files if they have been copied by explorer (Edit Menu - Copy) ie Paste them in to my application. They aren't present on the clipboard.
Do you know the answer or have you had a similar problem. Any pointers greatly appreciated
