Nice one!

The ProgId was set to MyOrg.web.publications.Test and not testInterop.Test!

So CreateObject("MyOrg.web.publications.Test") works!

class you are trying to create?

Now that I have got the mickey mouse .NET interop problem sorted (exposing
.NET library to ASP/VB6), I want to demo the real problem I am having.

What I want to achive is actually expoing a C#.NET Class Library for making
Web Service calls to ASP pages.

From my mickey mouse example, I learnt the following:
1) It's best to define interfaces as follows:
--------------------start of interface--------------------
using System.Runtime.InteropServices;
namespace MyOrg.web.publications
{

//[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://twoten.press.
net/webservices/")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsDual)]
public interface ITest
{
 void DoSomething();
}
}
--------------------end of interface--------------------
2) The class, I just need to implement the interface (other than using
[ClassInterface(ClassInterfaceType.AutoDual)])
3) install the .NET dll into gac
4) use regasm to install the type library
5) the DLL usable with Late Binding:
    e.g. Set objTest = CreateObject("MyOrg.web.publications.Test")

***The real real use/problem I am having is as follows:
(The code for the web service client class library is as follows)
---------------Start of WebService client Class Library Code---------------
using System.Diagnostics;
using System.Xml.Serialization;
using System;
using System.IO;
using System.Web.Services.Protocols;
using System.ComponentModel;
using System.Web.Services;
using System.Runtime.InteropServices;

namespace MyOrg.web.publications
{

 }

 public void PlaceOrder(SimpleOrderData order)
 {
  try
  {
   StreamWriter fileStream;
   fileStream = File.CreateText("c:\\temp\\test.txt");
   fileStream.WriteLine("TestOrder=" + order.TestOrder);
   fileStream.WriteLine("FirstName" + order.FirstName);
   fileStream.WriteLine("Surname" + order.Surname );
   fileStream.WriteLine("order.OrderLines(0).StockCode" +
order.OrderLines[0].StockCode);
   fileStream.Flush();
   fileStream.Close();
   //fileStream.WriteLine("" + );
   // this.Invoke("PlaceOrder", new object[] {
   //             order});
  }
  catch (Exception ex)
  {
   System.Diagnostics.Trace.WriteLine(ex);
  }
 }

 /// <remarks/>
 public System.IAsyncResult BeginPlaceOrder(SimpleOrderData order,
System.AsyncCallback callback, object asyncState)
 {
  return this.BeginInvoke("PlaceOrder", new object[] {
                  order}, callback, asyncState);
 }

 /// <remarks/>
 public void EndPlaceOrder(System.IAsyncResult asyncResult)
 {
  this.EndInvoke(asyncResult);
 }

 }
---------------End of WebService client Class Library Code---------------

1) I could compile, gacutil /i and regasm the class library with no problem
2) When I try to use it in ASP as follows:
2.1) Set objOnlyOrder         =
CreateObject("MyOrg.web.publications.SimpleOrderData")
2.2) I get the following error:
------------------------start of asp error------------------------
Active Server Pages error 'ASP 0115'

Unexpected error

/test.asp

A trappable error (C0000005) occurred in an external object. The script
cannot continue running.
------------------------end of asp error------------------------
3.1) If I try to use it from VBA with Early Binding, then there are no
errors, but the class library doesn't seem to be reading reading in the
write value by writing to "C:\temp\test.txt" (it simply creates a blank
test.txt file)!
-------------------------start of VBA Code-------------------------
Dim objOnlyOrderLine  As New iPubClient.OrderLine
Dim objOnlyOrder As New iPubClient.SimpleOrderData
Dim objIPubClient As New iPubClient.Order
Dim arrOrderLines(0) As String

objOnlyOrderLine.StockCode = "A123"
objOnlyOrderLine.Quantity = 2

objOnlyOrder.TestOrder = True
objOnlyOrder.FirstName = "Mickey"
objOnlyOrder.Surname = "Mouse"

arrOrderLines(0) = objOnlyOrderLine
objOnlyOrder.OrderLines = arOrderLines

MsgBox "before"
objIPubClient.PlaceOrder objOnlyOrder
MsgBox "after"
Set objOnlyOrderLine = Nothing
Set objOnlyOrder = Nothing
Set objIPubClient = Nothing
-------------------------End of VBA Code-------------------------
