you cant drag a class into a form, the whole idea of the Class is that you can have various functions relating to one class.
Public Class MyModules
Public Shared Function getConnectionString() As String
getConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("TestConnectionString").ToString()
So if i want to get the connection string for my database, i would use this code:
As you can see, MyModules is the class, getConnectionString is a function of that class.
