'Declaration
Public ReadOnly Property HasChanges As Boolean
Property Value
Boolean value indicating whether one of the result sets has changed.
Remarks
If you are not using the OnChange event, you can check the HasChanges property to determine if the query results have changed.
Note that once the value of this property is set to true, it remains true forever. In other words, to continue tracking for changes you have to use the OnChange event or create another instance of the MySqlDependency class.
