Null return

[jmprescott]

I'm writing a program to get a MD5 hash from web page data. The hash part is working fine, but I'm having troubles getting the web page data. I threw up a couple messageboxes and I'm getting a null string return, so I'm hashing nothing. Anyone see where the problem might be? Thanks!

Well its a long shot, but you bomb out of your loop whenever count < = 0. What if not all the data has arrived yet (or none as apprived yet) and you read a zero because its not there yet? You exit out of the loop prematurely.
Try sticking an Application.DoEvents(); inside your loop somewhere. See if that helps any?

That helped. It was never entering main, so nothing was happening.

Fixed, thank you :)
