FTP Upload

Ive been reading RFC 959 for a while now, and i just can't figure it out. im trying to connect to an ftp and upload a file, the following is the code that im using. however, it never actually uploads the file :( please help, thanks

string LocalFile = "stats.txt";
ftpMsg("USER " + UserName);
ftpMsg("PASS " + ftpPass);
ftpMsg("CWD public_html");
ftpMsg("PASV");
ftpMsg("STOR " + LocalFile);


it connects to the ftp fine, its just the uploading, thanks

Upload the program, that snippet doesn't tell us much at all
