1. Open your Visual Studio and create a new DataSet with the name "AdventureWorks.xsd".
2. Select "Pointer" in the "Toolbox" and drag "TableAdapter" to the new "DataSet".
3. Create or select a connection to SQL Server AdvantureWorks Sample Database.
4. Input "SELECT ProductID, Name FROM Production.vProductDescription WHERE (CultureID = N'en') as SQL Statements.
5. Establish a new column by right clicking "vProductAndDescription" on the dataset, then name the column.
6. Change the data type to "System.Byte[]".
7. Switch to "Solution Explorer" and add a new "Report" item.
8. Create a new "Report" item and insert a table to the report.
9. Add three columns in the dataset to the report table details section.
10. Drag and drop "Image" item to the last column and name it "Barcode".
11. Go to "Properties" window and change "Source", "MIMEType", "Value" to "Database", "image/jpeg", "=Fields!Barcode.Value" respectively.
12. Then select "Form1.cs[Design]", drag "ReportViewer" to Form1, and bind the data collection.
13. Add reference "KeepAutomation.Barcode.RDLC.dll" to your project.
14. Compile the following C# & VB sample codes into the method Form1_Load.
15. Use "KeepAutomation.Barcode.RDLC" namespace and run your project.

     private void Form1_Load(object sender, EventArgs e)
     {
     // load data to the data table this.vProductAndDescriptionTableAdapter.Fill 
     this.vProductAndDescriptionTableAdapter.Fill(this.AdventureWorks.vProductAndDescription);
     // create a linear barcode object 
     BarCode upca = new BarCode();
     // set barcode type 
     upca.Symbology = KeepAutomation.Barcode.Symbology.UPCA;
    // draw barcodes for each data row 
     foreach (AdventureWorks.vProductAndDescriptionRow
     row in this.AdventureWorks.vProductAndDescription.Rows)
     {// set barcode encoding data value 
     upca.CodeToEncode = row.ProductID.ToString();
     // set drawing barcode image format 
     upca.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;

     row.Barcode = upca.generateBarcodeToByteArray();
     }
     this.reportViewer1.RefreshReport();
     }

     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 upca As New BarCode()
     ' set barcode type 
     upca.Symbology = KeepAutomation.Barcode.Symbology.UPCA
     ' draw barcodes for each data row 
     For Each row As AdventureWorks.vProductAndDescriptionRow In Me.AdventureWorks.vProductAndDescription.Rows
     ' set barcode encoding data value 
     upca.CodeToEncode = row.ProductID.ToString()
     ' set drawing barcode image format 
     upca.ImageFormat = System.Drawing.Imaging.ImageFormat.Png

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