1. Download and unzip the trial version of RDLC EAN-128 Barcode Generator.
2. Create a new DataSet in your Visual Studio with the name "AdventureWorks.xsd".
3. Select "Pointer" in the "Toolbox" and drag "TableAdapter" to the new "DataSet".
4. Create or select a connection to SQL Server AdvantureWorks Sample Database.
5. Input "SELECT ProductID, Name FROM Production.vProductDescription WHERE (CultureID = N'en') as SQL Statements.
6. Establish a new column by right clicking "vProductAndDescription" on the dataset, then name the column.
7. Change the data type to "System.Byte[]".
8. Add a new "Report" item in "Solution Explorer".
9. Create a new "Report" item and insert a table to the report.
10. Add three columns in the dataset to the report table details section.
11. Drag and drop "Image" item to the last column and name it "Barcode".
12. Change "Source", "MIMEType", "Value" to "Database", "image/jpeg", "=Fields!Barcode.Value" respectively in "Properties" window.
13. Then select "Form1.cs[Design]", drag "ReportViewer" to Form1, and bind the data collection.
14. Add reference "KeepAutomation.Barcode.RDLC.dll" to your project.
15. Copy C# & VB sample codes below into the method Form1_Load and use "KeepAutomation.Barcode.RDLC" namespace.
16. Debug to see the created EAN-128 barcode image.

     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 ean128 = new BarCode();
     // set barcode type 
     ean128.Symbology = KeepAutomation.Barcode.Symbology.EAN128;
    // draw barcodes for each data row 
     foreach (AdventureWorks.vProductAndDescriptionRow
     row in this.AdventureWorks.vProductAndDescription.Rows)
     {// set barcode encoding data value 
     ean128.CodeToEncode = row.ProductID.ToString();
     // set drawing barcode image format 
     ean128.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;

     row.Barcode = ean128.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)

     Dim ean128 As New BarCode()
     ' set barcode type 
     ean128.Symbology = KeepAutomation.Barcode.Symbology.EAN128
     ' draw barcodes for each data row 
     For Each row As AdventureWorks.vProductAndDescriptionRow In Me.AdventureWorks.vProductAndDescription.Rows
     ' set barcode encoding data value 
     ean128.CodeToEncode = row.ProductID.ToString()
     ' set drawing barcode image format 
     ean128.ImageFormat = System.Drawing.Imaging.ImageFormat.Png

     row.Barcode = ean128.generateBarcodeToByteArray()
     Next
     Me.reportViewer1.RefreshReport()
     End Sub
