Solution 1

Are you sure that the method is exposed via COM ? Did it occur to you that if you're calling a VB class via COM, it would be easier to pass in your XML string and work with a .NET DOM class to parse it ?

Thanks for reply Christian. I have not tried yet, what you are suggesting. I will sure try this.

Just want to mention how am I doing everything
I have strong named my dot net dll , added to GAC and also registerd through RegAsm. I have one doubt here I am using Interop.MSXML2.dll version 4.0.0.0 and when I create an object in Classic asp page through Server.CreateObject("MSXML2.DOMDocument") then I think it creates object of the version which is in "C:\WINXP\System32". This is MSXML2 version 2.6.0.0. Can that be a problem.

there are two things that want to mention

First, I tried creating my dot net windows application and added the reference of the Interop.MSXML2.dll which is being referred by my dot net dll it works fine.

Second, I tried to create and Interop of the MSXML2 version 2.6 and strong named it and also added to GAC. Now I referenced this version in my dot net dll. I again put my dot net dll into GAC and then register through REgASM.

This time the error is

Error Type:
(0x80070002)
/TestWeb/Emp.asp, line 35
