' Description:  This module was copied from MSDN Library Visual Studio 6.0
'               and I made some Little changes to the code.
'               The purpose of functions in this module are:
'               1. Add Addin-Project to Add-In Manager List
'               2. Show de Printer Setup Dialog Through API Call
