Examples

Call the ApplicationDataContainer.CreateContainer | createContainer method to create a settings container.

The Always | always value from the ApplicationDataCreateDisposition enumeration indicates that the container should be created if it does not already exist.

Use the ApplicationDataContainer.Values | values property to access the exampleSetting setting in the exampleContainer container.

Call the ApplicationDataContainer.DeleteContainer | deleteContainer method to delete the exampleContainer settings container when you have finished with it.


Dim localSettings As Windows.Storage.ApplicationDataContainer = Windows.Storage.ApplicationData.Current.LocalSettings

' Create a setting in a container

Dim container As Windows.Storage.ApplicationDataContainer = 
   localSettings.CreateContainer("exampleContainer", Windows.Storage.ApplicationDataCreateDisposition.Always)

If localSettings.Containers.ContainsKey("exampleContainer") Then
    localSettings.Containers("exampleContainer").Values("exampleSetting") = "Hello Windows"
End If

' Read data from a setting in a container

Dim hasContainer As Boolean = localSettings.Containers.ContainsKey("exampleContainer")
Dim hasSetting As Boolean = False

If hasContainer Then
    hasSetting = localSettings.Containers("exampleContainer").Values.ContainsKey("exampleSetting")
End If
