Windows control library in Internet Explorer

Hi there, I'm trying to put a Windows control library that I created into a web page. The problem is when the page loads, I don't see anything, I just see a box where the control is supposed to be, but the control doesn't seem to load. I tried putting this control library into a regular windows form, and it works fine... Anyone know what the problem might be? The only thing I might see as a problem is that the control library has to connect to a database... But for now, both web server and database server are located on my local machine, so I just connect to the DB using Data Source=(local). Thanks in advance!!
