Drag and drop simulation?

Question

I have a proprietary application with the only way to transfer data from outside - drag and drop from another application (for example, drag and drop a file from Windows Explorer). My question is: is it possible to simulate drag'n'drop from an external application? A clean win32 option is preferred, dependencies such as MFC and WTL may also be included. Help!

Answer 1

I think this is possible, but for this you will probably need COM (although I'm not sure if there is a WM_DROPFILES message and some related functions, but I could not find it to delete the data). See this article on MSDN.
