Where I work we often need to invoke methods on a COM object that has been developed in VB6 or in .NET. I wrote this helper class for speed it along.

public static class ActiveX
{
    public static object Invoke(string @namespace, string @class, string method, params object[] parameters)
    {
        var progId = string.Format("{0}.{1}", @namespace, @class);
        return Invoke(progId, method, parameters);
    }

    public static object Invoke(string progId, string method, params object[] parameters)
    {
        var type = Type.GetTypeFromProgID(progId);
        var comObject = Activator.CreateInstance(type);

        return type.InvokeMember(method, BindingFlags.InvokeMethod, null, comObject, parameters);
    }
}
