Oh, oops, thought I mentioned that. C#

I just started with C# a few days ago. I'm trying to adapt a few examples from my companies SDK into DLL libraries. What I'd like to be able to do is have the DLL return an image object...or something... that can be displayed in a picture box. I could write it to a file, then read that file, but I'd like to be able to provide live feed, so it would be inefficient to write it to a file each time
