How to load / call functions from a VB DLL

A brief overview on how to create a DLL in VB .Net which can be used from within Matlab.

A brief overview on how to create a DLL (Dynamically Linked Library) in VB (Visual Basic) .Net which can be used from within Matlab. This is done using the actxserver command. One needs to use an approach like this instead of using the "loadlibrary" command, as one does not have the appropriate header file.
Hopefully this will provide a starting point for people like me who need some indication on where to start.

the zip contains:
- Step By Step Instructions in a PDF Document
- A Visual Studio 2008 VB.net DLL (Class) Project
- A Matlab file which shows how to call functions from the VB Dll, once it's been created

(I did this With Visual Studio 2008, and Matlab 2009a, but it should work with older versions too)
