Running a DLL containg an activex component from a browser

I've finally manage to get a Windows Control Library compiled to a dll running from a web browser with VB.NET. Though I have another problem. It occurs when I draw a activex component to the form. I upload all dll's generated in the bin directory to the server but the component won't run. Isn't it possible to run a activex control inside a dll on a webpage? Is the activex component automaticly registered when downloaded to the local computer so it's useable for clients?
