So what's the error? Does it compile? If so, what happens when you run it, and what did you expect to happen?

The subject

I agree. There is no UI involved here. Loh Peggie, please UseAMeaningfulSubjectLine. One that does explain the problem in a few words.

Assuming a web browser works from the same machine, you must be behind a proxying firewall, either on our own machine, or somewhere on the network you're attached to. As we don't know anything about your setup, we can't tell you precisely what to do, but this page gives the general procedure once you know something about the proxy you need to get through.

Did you post real code? There was a compiler error in what you posted originally; when I corrected that, it worked nicely for me.
