doh!

Had a look at this 'sendrequest' command, and what a dumbass I was, its not a command at all. I should of looked at the code a little closer, it was a function the programmer had created, so I copied the code into VB6 and tried to run it, unfortunately it requires MSXML to run, I may be able to get a copy, but first I would like to explore into other methods I could use, that way I can pursue the method that suits me best, I've done some researching and I've found something called inet and winsock, winsock looks most promising as it appears to run in a standard exe project on VB6, this is the type of programming I'm most familiar with.

I'll report back soon :)
