VbScript to automate a C# app? - 8/28/2005 11:26:16 AM

Hi all,

I am trying to create a VBScript to automate a C# app I wrote. I simplified this code below to illustrate the problem.

The problem is when I run my VbScript, I get the error: "ActiveX component can't create
object: 'getobject'. Error 800A01AD". Any ideas what I did wrong?

Here's my VBScript:
dim o
set o=getobject(,"ConsoleApplication2.Program")
msgbox o.TestString

And here's my C# application that's running when I try to access it from
VbScript:
using System;
using System.Collections.Generic;
using System.Text;
namespace ConsoleApplication2
{
public class Program
{
public string TestString = "testing 123";
static void Main(string[] args)
{
Console.ReadLine();
}
}
}

I now have it working, partially.

I can use CreateObject and create and then control the new instance of the C# code with VBScript. However, I cannot use an already running instance of the C# code using GetObject.

What I am trying to do is the same as when you control an instance of MS Word with VBScript using GetObject(,"Word.Application"). This command doesn't actually start Word, but instead uses the instance that's already open and running.

What I changed to get it working this far was to use the System.Runtime.InteropServices namspace, the [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)] and [ClassInterface(ClassInterfaceType.None)] tags, and created a new interface with the same name as the class and that begins with an underscore (class interface) and did the regasm /tlb option.

This is the last obstacle for me and I assume I am still doing something wrong.

Thanks in advance for any ideas.
