Adding a Reference At Runtime

Is it possible to add and remove a reference at runtime?  I have an app that needs to access a class in a com object when the program starts up, but needs to remove the reference from it after it is finished so it can copy a new version of the dll from the server to the pc it is running on.

As far as I know it isn't possible to add or remove a reference at runtime.  However, you should be able to use late binding to do the same thing:

Dim MyClass as Object

Set MyClass = CreateObject("Projectname.ClassName"")

Call MyClass.MySub()

If the new version of the DLL breaks compatibility, you will need to register it, which you can do by calling the DLLRegisterServer function in the DLL:

There are other methods to register or unregister COM components.  Let me know if you need more.
