Accessing a Running Application in Visual Basic

This section contains topics that cover how to use the Visual Basic Application model to control the application's run-time behavior, and topics that cover how to get run-time information about the application.

The My.Application object provides properties, methods, and events related to the current application. It allows you to get information about the application, such as the current culture, how the application was deployed, and the environment variables. The Visual Basic Application model exposed by the My.Application object allows an application to run code when the application starts up and shuts down. Similarly, the My.Application.Deployment property provides the current application's ClickOnce deployment object.
