My.Settings Object 

Provides properties and methods for accessing the application's settings.

Remarks

The My.Settings object provides access to the application's settings and allows you to dynamically store and retrieve property settings and other information for your application. For more information, see Managing Application Settings.

Properties

The properties of the My.Settings object provide access to your application's settings. To add or remove settings, use the Settings Designer. For more information, see How to: Add or Remove Application Settings.

Each setting has a Name, Type, Scope, and Value, and these settings determine how the property to access each setting appears in the My.Settings object:

  • Name determines the name of the property.

  • Type determines the type of the property.

  • Scope indicates if the property is read-only. If the value is Application, the property is read-only; if the value is User, the property is read-write.

  • Value is the default value of the property.
