Problem on upload file and set browser's proxy IP. Please Help!!

Hi Experts,

Assuming I have a very basic form. Have only one textbox, one label and 1 command button. After I type a file and click on the command button, it will upload the file to my webserver (and assume my file name typed correctly) But the problem is I don't know how to upload file to web server in VB. Can someone tell me the command/fucntions and it's parameters?

Also, is it possible if I want to set my IE browser's proxy with my applicaiton?

Thanks in advance

ps: I'm using VB.NET, I don't want to use ASP.NET.

Andy
