private void StartAnnotations()
{
    // If there is no AnnotationService yet, create one.
    if (_annotService == null)

    // If the AnnotationService is currently enabled, disable it.
    if (_annotService.IsEnabled == true)
        _annotService.Disable();

    // Open a stream to the file for storing annotations.
    _annotStream = new FileStream(
        _annotStorePath, FileMode.OpenOrCreate, FileAccess.ReadWrite);

    // Create an AnnotationStore using the file stream.
    _annotStore = new XmlStreamStore(_annotStream);

    // Enable the AnnotationService using the new store.
    _annotService.Enable(_annotStore);
}// end:StartAnnotations()
