[QUOTE="Guan, post: 2006353"]
Hi Arne,

Add to that i am also using NetComponents class. My purpose is to
create a Web Based ftp to upload the file to the ftp server. So far i
can only upload .txt and .zip.  If i upload other file using
ENCTYPE="multipart/form-data". I will receive some error.

Thanks for replying my posting.
