INET Control, Uploading Files With POST Method

Hi,

I have come across a problem that has me stumped. I have a client whom wishes me to upload files via a VB application to his website (graphics etc). I Know the FTP element of the VB INET component would be ideal, but his host server does not support FTP transfers, so the only way to send the files is with a POST (Inet1.Execute strURL, "POST", ????)method (multipart/form-data). I know it can be done from a simple HTML page, but can I do it straight from VB6.0 Pro? If so, could you give me any clues, hints or point me in the direction of any sample code?

Many thanks,
Gary
