    How to find out the number of GdPicture/XMP annotations on the currently displayed page.
    'We assume that the GdViewer1 control has been properly integrated
    'and your document has been properly displayed as well.
    Dim annotCount As Integer = GdViewer1.GetAnnotationCount()
    Dim message As String = "The number of GdPicture/XMP annotations on the current page: " + annotCount
    Dim annot As GdPicture14.Annotations.Annotation = Nothing
    If annotCount > 0 Then
        annot = GdViewer1.GetAnnotationFromIdx(0)
        message = message + vbCrLf + "The author of the first one is: " + annot.Author
    End If
    MessageBox.Show(message, "GdViewer.GetAnnotationCount")
    //We assume that the GdViewer1 control has been properly integrated
    //and your document has been properly displayed as well.
    int annotCount = GdViewer1.GetAnnotationCount();
    string message = "The number of GdPicture/XMP annotations on the current page: " + annotCount;
    GdPicture14.Annotations.Annotation annot = null;
    if (annotCount > 0)
    {
        annot = GdViewer1.GetAnnotationFromIdx(0);
        message = message + "\nThe author of the first one is: " + annot.Author;
    }
