• .NET Development Environments: Visual Studio 2005/2008 /2010 installed, .NET Version greater than 2.0, C#.NET & VB.NET
• Compatible Operating Systems: Windows 2000, XP, Vista, and Windows 7
• Minimum System Requirements: 500 MHZ processor, 128 MB RAM, 5 MB available hard drive space

• Microsoft Windows XP
• Microsoft Visual Studio 2005
• Visual C#.NET

1. Open your Visual Studio and create a new WinForms project, then create a "DataSet" with the name "AdventureWorks.xsd".
2. Drag "TableAdapter" item under the "Toolbox" to the new "DataSet".
3. Link the connection to SQL Server AdventureWorks Sample Database.
4. Copy "SELECT ProductID, Name FROM Production.vProductAndDescription WHERE (CultureID = N'en') " as SQL Statement.
5. Right-click "vProductAndDescription" on the dataset to create a column (named as "Barcode"), and change the data type to "System.Byte[]" in "Properties" window.
6. Go to "Solution Explorer" and create a new "Report" item.
7. Insert a table to your report and 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.
11. Click "Report1.rdlc[Design]", then click "Report" and choose "Data Sources....", click "Add to Report" & lastly click "OK".
12. Add reference "KeepAutomation.Barcode.RDLC.dll" to your project.
13. Right click "Form1.cs" and select "View Code", then compile the following sample code.
14. Use "KeepAutomation.Barcode.RDLC" namespace and debug.

     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 barcode = new BarCode();
     // set barcode type 
     barcode.Symbology = KeepAutomation.Barcode.Symbology.Code11;
     // draw barcodes for each data row 
     foreach (AdventureWorks.vProductAndDescriptionRow
     row in this.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();
     }
     this.reportViewer1.RefreshReport();
     }

1. Open your Visual Studio and create a website project, and add "KeepAutomation.Barcode.RDLC.dll" to reference.
2. Right click your project In "Solution Explorer" to add a new "Class" item.
3. Copy the sample code into the "Class" item. Go to "Build" tab and choose "Build Web Site".
4. Go to "Solution Explorer" and right click your web project to add a new "Report" item.
5. Go to "Toolbox" and drag "Table" in "Report Items" to the report. Then, go to "Website Data Sources" tab and insert "BarcodeName" and "BarcodeId".
6. Insert "Image" item to the last column and name it as "Barcode".
7. Revise "Source" to "Database", "MIMEType" to "image/jpeg", "Value" to "=Fields!Byte.Value" respectively in "Properties" window.
8. In "Solution Explorer", right click "Default.aspx" and select "View Designer" to add a "ReportViewer" to the project
9. Choose your created report and run your ASP.NET web project.
