Passing Barcode to report.rdlc through parameter in .vb-CodePudding

I have a barcode in PictureBox1 and I want to pass it over to the image in report.rdlc through parameters but since the barcode is not a typical image like .png, .jpg, etc. I am getting an error “value should not be null” but it works with .png image though.

Here’s my code:

Dim ms As New MemoryStream
        Form1.PictureBox1.Image.Save(ms, Form1.PictureBox1.Image.RawFormat)
        Dim arrPic As Byte()
        arrPic = ms.ToArray
        Dim images As String = Convert.ToBase64String(arrPic)

    Dim param As IList(Of ReportParameter) = New List(Of ReportParameter)
    param.Add(New ReportParameter("Address", Form1.TextBox4.Text))
    param.Add(New ReportParameter("img", images, True))     
  ReportViewer1.LocalReport.SetParameters(param)
   Me.ReportViewer1.RefreshReport()

CodePudding user response：

You add an image to your RDLC report and set the following properties of the image:

MIMEType <to your image's mime type> Ex image/png, image/jpeg, etc
Source = Database
Value = =System.Convert.FromBase64String(Parameters!img.Value)
