Main Differences Between Class and Module in Visual Basic

The main differences between a class and a module in Visual Basic lie in their structure and behavior.

• Definition: A class is a blueprint for creating objects, allowing for the creation of multiple instances with distinct characteristics. On the other hand, a module is a container for similar procedures and functions that can be accessed without creating an instance.
• Instance: Objects of a class need to be instantiated before they can be used, while modules do not require instantiation and are accessed directly.
• Inheritance: Classes support inheritance, allowing for the creation of a hierarchy of classes with shared characteristics. Modules do not support inheritance.
• Access: Classes provide scope control through access modifiers like Public, Private, Protected, etc. Modules are generally considered Public by default and can be accessed from any part of the code.

Overall, classes are used for creating objects with specific properties and behaviors, while modules are used for organizing related procedures and functions for easy access.
