FTP uploading via winsock

[RosauraBWM]

Hello ,

I have a source code that could potentially upload files onto an FTP server using winsock. But there seems to be a small glitch and the files are not getting uploaded. Could someone please guide me as to why this is happening. I would be forever indebted. thanks in advance
