posted byJohn_JacobinTutorials & Tips
VB.NET 2005 Free Training : Visual Studio.NET Namespaces - The .NET Framework class library has thousands of classes which are needed for developing and deploying solutions. In order to organize all those classes for ease of use .NET Framework uses namespaces. This Gives the Classes their own space and prevents conflicts between the various names in these classes. For instance if two classes contain a method Paint(), then to avoid conflicts in names we can place these classes in two different namespaces. Thus namespaces allow classes to be grouped in a consistent, hierarchical manner.

posted byJohn_JacobinTutorials & Tips
Implementing Class Library Object in VB.NET 2005
Class: Classical Object Oriented Concepts explain a class as a cookie cutter. A class allows you to create objects of the class. As a programmer you define a class with data fields, properties, methods and events. Then you can create objects based on that class that have state (fields, properties) and behavior (methods, events). A class can be considered as a specification of how the object of the class should look like and behave.
