Hi all,
I have a problem while working on a dotnet assembly control in a
web page. I wrote on interop group without any answer, and now i try
here.

I'm tring to send codebehind the "css" style as an object. I
publish a propery of type "object" and I'm tying to cast this object
as a know type (because the type after the property population is
"system.__comobject").

I tried add a recerence of the microsoft.mshtml library, in order to
find an appropriate class to cast my comobject but when I instanciated
each class inside this namespace I had a security permission error
like this:

************** Exception Text **************
System.Security.SecurityException: Request for the permission of type
'System.Security.Permissions.SecurityPermission, mscorlib,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
failed.
