         barcode.Symbology = KeepAutomation.Barcode.Symbology.Code128A
         barcode.CodeToEncode = TextBox1.Text
         barcode.X = 1
         barcode.Y = 60
         barcode.BottomMargin = 10
         barcode.TopMargin = 10
         barcode.LeftMargin = 10
         barcode.RightMargin = 10
         barcode.DisplayText = True
         barcode.Orientation = KeepAutomation.Barcode.Orientation.Degree0
         barcode.BarcodeUnit = KeepAutomation.Barcode.BarcodeUnit.Pixel
         barcode.DPI = 72
         barcode.TextFont = New Font("Arial", 10.0F, FontStyle.Bold)
         barcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg
         barcode.generateBarcodeToImageFile(Application.StartupPath & "\Barcode\" & TextBox1.Text & ".jpeg")
