Difference Between Dim and WithEvents Keywords in VB.Net

One key difference between a variable declared using the Dim keyword and a variable declared using the WithEvents keyword in VB.Net is how they are used with events.

Dim Keyword: Variables declared using the Dim keyword are local variables that are scoped within a specific method or block of code. They are not directly associated with any events and do not support event handling.

WithEvents Keyword: Variables declared using the WithEvents keyword are typically used when working with controls or components that raise events. These variables can be used to handle events raised by the associated control or component.

In summary, the main difference is that WithEvents allows the variable to be associated with events and enables event handling capabilities, while Dim is simply used for general variable declaration without event-related functionality.
