Code 39 Generation in RDLC in .NET WinForms Applications

1. Open Visual Studio and create a new Windows Forms project naming "RDLC Barcode Demo";
2. Add a new "DataSet" to the project:
• Create a new "DataSet" and name it "AdventureWork.xsd";
• Drag and drop "TableAdapter" to your created DataSet in toolbox;
• Create a new connection or use existing connection to SQL Server AdventureWorks Sample Database;
• Keep "Use SQL statements" to access the database and input "SELECT ProductID, Name FROM Production.vProductAndDescription WHERE (CultureID = N'en')" as SQL statements;
• Right click "vProductAndDescription" on the DataSet to create a new column in the "DataTable" and name it "Barcode";
• In the "properties" window, change this barcode "DataType" to "System.Byte[]";
3. Create a new report:
• Create a new report and name "Report1.rdlc";
• Drag and drop a "Table" onto the report;
• Add three columns in DataSet "AdventureWorks.xsd" to the report table details section, and drag an "Image" to the last column "Barcode";
• In the "properties" window, set image item property "MIMEType" to "image/jpeg", "Source" to "Database" and "Value" to "=Fields!Barcode.Value";
4. Drag "ReportViewer" control:
• Drag a "ReportViewer" to "Form1.cs";
• Choose "Report1.rdlc" report, and click "Rebind Data Source";
• In the "Report.rdlc" page, click "Report", and select "Data Source";
• Add "AdventureWorks_vProductAndDescription" to report data source;
5. Add "Avapose.linearbarcode.winforms.dll" to .NET project reference from the "Solution Explorer";
6. Copy the following code accordingly into the method Form1_Load and run the project. You can get the Code 39 images displayed on the report.

private void Form1_Load(object sender, EventArgs e)
{
// load data to the data table this.vProductAndDescriptionTableAdapter.Fill
(this.AdventureWorks.vProductAndDescription);
// create a linear barcode object
Linear barcode = new Linear();
// set barcode type 
barcode.LinearBarcode = LinearBarcode.Code39;
// draw barcodes for each data row
foreach (AdventureWorks.vProductAndDescriptionRow 
row in this.AdventureWorks.vProductAndDescription.Rows)
{// set barcode encoding data value
barcode.Data = row.ProductID.ToString();
// set drawing barcode image format
barcode.Format = System.Drawing.Imaging.ImageFormat.Jpeg;
row.Barcode = barcode.drawBarcodeAsBytes();
}
this.reportViewer1.RefreshReport();
}

Private Sub Form1_Load(ByVal sender 
As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code 
loads data into the 'AdventureWorks.vProductAndDescription' table.
You can move, or remove it, as needed.
Me.vProductAndDescriptionTableAdapter.Fill
(Me.AdventureWorks.vProductAndDescription)
Dim barcode As New Linear()
barcode.LinearBarcode = LinearBarcode.Code39
Dim row As AdventureWorks.vProductAndDescriptionRow
For Each row In Me.AdventureWorks.vProductAndDescription.Rows
' set barcode encoding data value
barcode.Data = row.ProductID.ToString()
' set drawing barcode image format
barcode.Format = System.Drawing.Imaging.ImageFormat.Png
row.Barcode = barcode.drawBarcodeAsBytes()
Next
Me.ReportViewer1.RefreshReport()
End Sub
