Development with My (Visual Basic)

Visual Basic provides new features for rapid application development that improve productivity and ease of use while

delivering power. One of these features, called My, provides access to information and default object instances that are

related to the application and its run-time environment. This information is organized in a format that is discoverable

through IntelliSense and logically delineated according to use.

Top-level members of My are exposed as objects. Each object behaves similarly to a namespace or a class with Shared

members, and it exposes a set of related members.

This table shows the top-level My objects and their relationship to each other.
