Barcodes in MS VB.NET and C#

A word of caution: You might be tempted to import the ActiveX Control BarCodeWiz.dll by clicking on Tools > Choose Toolbox Items... > COM Components > Browse... .

However, Visual Studio does not import the properties correctly.  When accessing the Picture property in a project compiled for x64 or Any CPU, an exception "A generic error occurred in GDI+" is thrown.

Instead, use the supplied Interop Assemblies as outlined in the steps below to ensure compatibility with both 32 and 64-bit projects.

• With .NET Framework Components selected, click Browse...

• Select AxBARCODEWIZLib.dll. The default location of the file is:
  C:\Program Files\BarCodeWiz\BarCodeWiz ActiveX Control\Dll\Interop\4.0\AxBARCODEWIZLib.dll

• Click Project > Add Project Reference...

• Click on the Browse tab and select BARCODEWIZLib.dll. The default location of the file is:
  C:\Program Files\BarCodeWiz\BarCodeWiz ActiveX Control\Dll\Interop\4.0\BARCODEWIZLib.dll

• AxBarCodeWiz is now available in the toolbox. Drag it onto a form as you would any other control.

Public Class Form1
  Private Sub Button1_Click(ByVal sender As System.Object, _
                          ByVal e As System.EventArgs) Handles Button1.Click

      'Set the barcode properties.
      AxBarCodeWiz1.Symbology = BARCODEWIZLib.enumSYMBOLOGY.Code_128_Auto
      AxBarCodeWiz1.Barcode = "HELLO 123"

      Dim pd As New System.Drawing.Printing.PrintDocument
      AddHandler pd.PrintPage, AddressOf pd_PrintPage

      Dim pp As New PrintPreviewDialog
      pp.Document = pd
      pp.ShowDialog(Me)
