Control ActiveX in ASP.NET 2.0

Hi everybody.

I must embed a windows application user control in an ASP.NET page. (I think
this is like a control ActiveX).

For do this, I create a class library project with COM communication
allowed, and create my UserControl.

Then, I write the following tag in my ASP.NET page:
<object id="id" name ="name" classid="assemblyPath#userControlFullName"
width="width" height="height"/>.

And it's supposed that it must work, but it doesn't. However, it works for
ASP.NET 1.1.

Am I missing something? Any suggestion?

Thanks in advance.
