So do:
Type the name of a class that is within the DLL, and a red line will appear at the end.
Hover the mouse over it, and click on the drop down that appears.
It will give you the option of adding the appropriate Imports statement, and off you go.

IF you added a reference, your project has new classes, which you can create after adding the namespace of your dll ( assuming it's not COM, if it's COM, you got a proxy class per object exposed ). Then you can create objects as normal.

You can use reflection together with the Activator class. Use the activator class to create the instance of the class present in the dll and then invoke the methods.

I have provided a solution here in my blog : http://tarundotnet.wordpress.com/2011/06/30/how-to-dynamically-load-assemblies/[^] .
The code is in C Sharp but you can use this converter to convert to VB.NET : http://www.developerfusion.com/tools/convert/csharp-to-vb/[^]

Hope it helped. :thumbsup:
