        OpenFileDialog1.CheckFileExists = True
        OpenFileDialog1.CheckPathExists = True
        OpenFileDialog1.DefaultExt = "pdf"
        OpenFileDialog1.Filter = "pdf File|*.pdf"
        OpenFileDialog1.InitialDirectory = "C:\"
        OpenFileDialog1.Multiselect = False
        OpenFileDialog1.FileName = filePDF.Text.ToString
        OpenFileDialog1.ShowDialog()
