My COM works fine with old ASP, but when I wrap it and try to use in inASP.NET I get a System.Runtime.InteropServices.COMException: Object variable or With blockvariable not set. I have referenced the COM - which when VS.Net creates the wrapper it alsopulls in the ASPTypeLibrary as well. Is there something special I need todo. All of my other methods inside the COM work fine, but the methods thathave output (Response.Write) calls, throw this exception every time.

There's a flag you have to set to have ASP.NET expose the old ASP
objects, it doesn't do it by default. add this to the top of your aspx
files.

<%@ Page aspCompat=3D"true" %>

Cheers
