I know there are several FTP UDF's, but I had trouble finding examples. I also had a little trouble finding TCP sending systems that worked. And those that did work, didn't have a gui or anything. So I made a simple TCP file transfer system with a gui. It is for learning purposes. It isn't a big program, just an small, working example of how to use TCP protocol. Tell me how you like it.
