I have an application that I update frequently...

I would like to have the application open a .txt file from my web site, read it's contents to determine the latest version, and if necessary, inform the user that an update exists.

Problem is, I haven't the slightest idea how to begin.

Anyone have any good pointers?

I would presume it's a WinSock or INet control thing, but I'm not familiar with them, so have no idea how to use them...

Thanks!
