[C#]

The following code shows an example of using this interface in C#.

 public void WireArcScanEvents(IApplication app)
 {
  //You can get app from ICommand :: OnCreate() hook parameter
  if (app != null)
  {
    IVectorization vectorization=app.FindExtensionByName("ESRI ArcScan Tools") as IVectorization;
    ((IVectorizationEvents_Event)vectorization).OnRasterTargetChanged +=       new IVectorizationEvents_OnRasterTargetChangedEventHandler(OnRasterTargetChanged);  }
}
void OnRasterTargetChanged()
{
  System.Windows.Forms.MessageBox.Show("Raster Changed.");
}
   
[Visual Basic .NET]

The following code shows an example of using this interface in VBNet.

  Public Sub WireArcScanEvents(ByVal app As IApplication)
    'You can get app from ICommand :: OnCreate() hook parameter
    If Not app Is Nothing Then
      Dim vectorization As ESRI.ArcGIS.ArcScan.IVectorization=TryCast(app.FindExtensionByName("ESRI ArcScan Tools"), IVectorization)

      'Wire ArcScan events
      AddHandler (CType(vectorization, ESRI.ArcGIS.ArcScan.IVectorizationEvents_Event).OnRasterTargetChanged , _
        AddressOf OnRasterTargetChanged
    End If
  End Sub

  Private Sub OnRasterTargetChanged()
    System.Windows.Forms.MessageBox.Show("Raster Changed.")
  End Sub
