added your site to trusted sites and I could see the site, which did help alot to have the faith thatforms can be embedded in IE web  pages.

I have tried creting several Windows library Control and truied to embed them in an aspx page  but no, however if I open a new windows project  and try to include dll in that , it is fine.
<OBJECT id=UserControl1 height=280 width=280

classid=bin/mycontrol1.dll#mycontrol1.UserControl1
</object>
