      'Start Micro QR barcode scanning process
      Dim BarcodeCount As Integer = oGdPictureImaging.BarcodeMicroQRReaderGetBarcodeCount
      If BarcodeCount > 0 Then
         For i As Integer = 1 To BarcodeCount
            MessageBox.show("Barcode No: " & Str(i))
            MessageBox.show("Value: " & oGdPictureImaging.BarcodeMicroQRReaderGetBarcodeValue(i))
            MessageBox.show("Angle: " & oGdPictureImaging.BarcodeMicroQRReaderGetBarcodeSkewAngle(i).ToString())
