  2. Add "TableAdapter" item under the "Toolbox" to the new "DataSet".
  3. Using the connection to SQL Server AdventureWorks Sample Database.
  4. For SQL Statement, copy "SELECT ProductID, Name FROM Production.vProductAndDescription WHERE (CultureID = N'en') ".
  5. Right-click "vProductAndDescription" on the dataset to create a column named as "Barcode", and change its data type to "System.Byte[]" in "Properties" window.
  6. Then, create a new "Report" item and insert a table to your report.
  7. Add three columns in the dataset to the report table details section.
  8. Drag and drop "Image" item to the last column and name it "Barcode".
  9. Change "Source", "MIMEType", "Value" to "Database", "image/jpeg", "=Fields!Barcode.Value" respectively through "Properties" window.
  10. Drag "ReportViewer" under "Toolbox" to Form1 and bind the data collection.
  11. Add "KeepAutomation.Barcode.RDLC.dll" to your WinForms project reference.
  12. Refer to the following demo code.
  13. Use "KeepAutomation.Barcode.RDLC" namespace and run your project.
VB Sample code
     Private Sub Form1_Load(sender As Object, e As EventArgs)
' load data to the data table this.vProductAndDescriptionTableAdapter.Fill
Me.vProductAndDescriptionTableAdapter.Fill(Me.AdventureWorks.vProductAndDescription)
' create a linear barcode object
Dim barcode As New BarCode()
' set barcode type
barcode.Symbology = KeepAutomation.Barcode.Symbology.Codabar
' draw barcodes for each data row
For Each row As AdventureWorks.vProductAndDescriptionRow In Me.AdventureWorks.vProductAndDescription.Rows
' set barcode encoding data value
barcode.CodeToEncode = row.ProductID.ToString()
' set drawing barcode image format
barcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Png

row.Barcode = barcode.generateBarcodeToByteArray()
Next
Me.reportViewer1.RefreshReport()
End Sub
