Question

I\'d like to create a COM object in C#, and use it via IDispatch from JScript. That part is pretty simple.

I also want to implement simple callbacks on the COM objec

Answer 1

Wow, wow! May be easy?

using System;
using System.EnterpriseServices;

[assembly: ApplicationName("Calculator")]
[assembly: ApplicationActivation(ActivationOption.Library)]
public class Calculator : ServicedComponent
{
    public int Add(int x, int y){ return (x + y); }
}

then use these build command

 sn -k Calculator.snk           
 csc /t:library Calculator.cs
 regsvcs Calculator.dll

On jscript (wsh):

c = new ActiveXObject("Calculator");
WScript.Echo(typeof(c));  // output: object
WScript.Echo(c.Add(4,1)); // output: 5
