I've created a very simple user control which just has a label on it.
I followed the instruction but it doesn't show up. I don't know what's
wrong because there's no error message. It just showed an iframe-like
thing. Please let me know what went wrong. The user control itself can
be downloaded at

the .dll file cannot be downloaded.)
