Hi Daryl,

Alex is right, you can do it that way but you can also do it using a more VB
6 style. The CreateObject function is still available in VB.NET so you could
use:

Dim obj As Object
obj = CreateObject("MyComp.MyClass", "MyServer")
' use object
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj)
obj = Nothing

Note this code shows how to use the object late bound and requires Option
Strict Off. You can do this early bound by setting a reference to your
component and using a variable to the correct type, this would of course be
preferred.
