How to: Change User Settings in Visual Basic
You can change a user setting by assigning a new value to the setting's property on the My.Settings object.
The My.Settings object exposes each setting as a property. The property name is the same as the setting name, and the property type is the same as the setting type. The setting's Scope determines if the property is read-only: The property for an Application-scope setting is read-only, while the property for a User-scope setting is read-write. For more information, see.
Although you can change and save the values of user-scope settings at run time, application-scope settings are read-only and cannot be changed programmatically. You can change application-scope settings when creating the application, through the Project Designer, or by editing the application's configuration file. For more information, see.
This example changes the value of the Nickname user setting.
For this example to work, your application must have a Nickname user setting, of type String. For more information, see.
The application saves the user settings when the application shuts down. To save the settings immediately, call the My.Settings.Save method. For more information, see.
