The following code example uses the DisableNotifications method to disable change notifications for the database specified by the connection string MyConnectionString.

For the full code required to run the example, see the Example section of the SqlCacheDependencyAdmin class overview topic.


' Create a method to disable SqlCacheDependency
' change notifications for the Northwind database.
Public Sub DisableDatabase_Click( _
 sender As Object, e As System.EventArgs)

   SqlCacheDependencyAdmin.DisableNotifications( _
   "Northwind")
   Response.Write("Northwind database disabled at " _
   & DateTime.Now.ToString())

   ' An HttpException is thrown if adequate permissions to
   ' modify the database are not granted.
