How to create Avery Address Labels in WPF with C# or VB.NET featuring USPS Postnet Barcodes

Technologies used
  • Neodynamic Barcode Professional for WPF (any version)
  • Microsoft .NET Framework 3.0 or greater
  • Microsoft Visual Studio 2008
  • Microsoft Visual Basic 2008 Express Edition
  • Microsoft Visual C# 2008 Express Edition
This demo - which source code files can be found at the end of this page available for downloading - demonstrates how you can easily create Avery Address Labels featuring USPS Postnet barcode in WPF Applications. Barcode Professional for WPF provides vector-based barcode generation producing high quality barcodes.

This step-by-step guide illustrates how you can create Avery Address Labels featuring Postnet barcodes by leveraging WPF Document and Printing capabilities together Barcode Professional for WPF.

The following figure is a screenshot of the demo application will be creating.

WPF Avery Address Labels featuring USPS Postnet Barcode
During the course of this walkthrough, you will accomplish the following activities:
  • Create a WPF Application using Visual Studio 2008 or Express Editions.
  • Create a WPF User Control which will represent an individual label featuring USPS Postnet barcode by leveraging Barcode Professional for WPF
  • Create a .NET Class wrapping an Avery Address Label layout (In this case will be creating an "Ambassador Address Label � Avery 5160" and responsible of generating a FixedDocument object based on XML data source.
  • Create a simple WPF Window which will display the Avery Address Label through out a WPF DocumentViewer control.
Please follow these steps:
  • Ensure you have installed Barcode Professional for WPF
  • Launch Visual Studio and create a new WPF Application
  • Create a new folder in your project and name it "data" (without quotes)
  • Add the AdventureWorksEmployees.xml file inside Data folder. That XML file contains info about AdventureWorks employees including Name, Address, City, State and Postal Code
  • In this sample will be creating an "Ambassador Address Label � Avery 5160". This particular Avery Product features individual labels which size is 2.625 inch x 1 inch. We�ll create a WPF User Control which will represent each individual label and will hold a BarcodeProfessional WPF Control for encoding/generating USPS Postnet barcodes.
    • Add a new WPF User Control to the project and name it AveryBarcodeLabel
    • Resize the User Control to Width = 252 and Height = 96. The size value is calculated by translating the label size to WPF Device Independent Unit (DIU = 1/96th inch per unit). Based on our sample:

      Width = 2.625 * 96 = 252
      Height = 1 * 96 = 96


    • After that, drag & drop from VS Toolbox to the User Control:
      • 3 TextBlock
      • 1 BarcodeProfessional
    • The User Control elements layout should look like follows (bellow to the figure is the XAML code for reference) 
      <Grid>
    <TextBlock Height="21" Margin="8,8,8,0" Name="txtLine1" VerticalAlignment="Top" Text="Mailing Address Line 1" TextTrimming="CharacterEllipsis" FontFamily="Arial" FontSize="12" />
    <TextBlock FontFamily="Arial" FontSize="10" Margin="10,29,6,0" Name="txtLine2" Text="Mailing Address Line 2" TextTrimming="CharacterEllipsis" Height="17" VerticalAlignment="Top" />
    <TextBlock FontFamily="Arial" FontSize="10" Margin="10,46,6,33" Name="txtLine3" Text="Mailing Address Line 3" TextTrimming="CharacterEllipsis" />
    <my:BarcodeProfessional Margin="10,0,8,8" Name="bcPostnet" xmlns:my="clr-namespace:Neodynamic.WPF;assembly=Neodynamic.WPF.Barcode" DisplayCode="False" Symbology="Postnet" QuietZone="0" Height="28" VerticalAlignment="Bottom" AntiAlias="False" BarcodeAlignment="Left" />
</Grid>


    • Now in the User Control code-behind class, change it so it looks like follows:
      Visual Basic .NET 
      Partial Public Class AveryBarcodeLabel

    Public Sub New(ByVal line1 As String, ByVal line2 As String, ByVal line3 As String, ByVal zipCode As String)

        InitializeComponent()

        'set visual elements

        Me.txtLine1.Text = line1
        Me.txtLine2.Text = line2
        Me.txtLine3.Text = line3
        Me.bcPostnet.Code = zipCode

    End Sub

End Class
      Visual C# .NET 
      public partial class AveryBarcodeLabel : UserControl
{
    public AveryBarcodeLabel() : this("Line1","Line2","Line3","12345")
    {
    }

    public AveryBarcodeLabel(string line1, string line2, string line3, string zipCode)
    {
        InitializeComponent();

        //set visual elements
        this.txtLine1.Text = line1;
        this.txtLine2.Text = line2;
        this.txtLine3.Text = line3;
        this.bcPostnet.Code = zipCode;
    }
}


  • The "Ambassador Address Label - Avery 5160" features 30 labels per sheet and the sheet size as well as labels layout is the following:
    We'll create a class for wrapping this info and the same will be the responsible of generating a FixedDocument object displaying all labels from data source.
    • Add a new Class item and name it Avery5160
    • After that, paste the following code for Avery5160 class:
      Visual Basic .NET 
      Imports System.Data
Imports System.Windows.Markup

''' <summary>

                doc.Pages.Add(page);
            }
        }

        return doc;
    }
}
  • The last step is for designing the Window element for displaying the Avery Labels in a DocumentViewer control. Open default Window1 file at design time and drag & drop a TextBlock and a DocumentViewer control. The Window elements layout should look like follows (bellow to the figure is the XAML code for reference)
    Employees Avery Mail Address Labels With Postnet Barcode
    Employees Avery Mail Address Labels With Postnet Barcode
    <Grid>
    <DocumentViewer Margin="8,32,9,8" Name="documentViewer1" />
    <TextBlock Height="21" Margin="8,9,149,0" Name="textBlock1" VerticalAlignment="Top" Text="Employees Avery Mail Address Labels with Postnet Barcode" FontSize="14" />
</Grid>
    Finally, in the Window code-behind class:
    • Add the following methods:
      Visual Basic .NET 
      Private Function GetRootFolder() As String
	'Get root folder

        Dim contentDir As String = Directory.GetCurrentDirectory()
        Dim dirLength As Integer = contentDir.Length

        If (contentDir.ToLower().EndsWith("\bin\debug")) Then
            contentDir = contentDir.Remove(dirLength - 10, 10)
        ElseIf (contentDir.ToLower().EndsWith("\bin\release")) Then
            contentDir = contentDir.Remove(dirLength - 12, 12)
        End If

        Return contentDir
End Function

Private Function GetEmployees() As DataTable
        Dim ds As New DataSet()
        ds.ReadXml(Me.GetRootFolder() + "\data\AdventureWorksEmployees.xml")
        Return ds.Tables(0)
End Function
      Visual C# .NET 
      private string GetRootFolder()
{
    //Get root folder
    string contentDir = Directory.GetCurrentDirectory();
    int dirLength = contentDir.Length;

    if (contentDir.ToLower().EndsWith(@"\bin\debug"))
        contentDir = contentDir.Remove(dirLength - 10, 10);

    else if (contentDir.ToLower().EndsWith(@"\bin\release"))
        contentDir = contentDir.Remove(dirLength - 12, 12);

    return contentDir;
}

private DataTable GetEmployees()
{
    DataSet ds = new DataSet();
    ds.ReadXml(this.GetRootFolder() + @"\data\AdventureWorksEmployees.xml");
    return ds.Tables[0];
}
    • Add the following code in the Window_Loaded event procedure:
      Visual Basic .NET 
      Dim avery As New Avery5160()
Me.documentViewer1.Document = avery.CreateDocument(Me.GetEmployees())
      Visual C# .NET 
      Avery5160 avery = new Avery5160();
this.documentViewer1.Document = avery.CreateDocument(this.GetEmployees());
  • That's it. Run your project. You should get something like the following:
