[C#]

The following code shows an example of wiring traverse window events in C#.

public void WireTraverseWindowEvents()
{
  //You can get app from ICommand :: OnCreate() hook parameter
  UID editorUid = new UIDClass();
  editorUid.Value = "esriEditor.Editor";
  IEditor editor = app.FindExtensionByCLSID(editorUid) as IEditor;

  //Get a reference to the traverse window
  UID extUid = new UIDClass();
  extUid.Value = "esriEditor.TraverseWindow";
  ITraverseWindow traverseWindow = editor.FindExtension(extUid) as ITraverseWindow;

  //Wire traverse window events
  ((ITraverseWindowEvents_Event)traverseWindow).OnAddCourse += new ITraverseWindowEvents_OnAddCourseEventHandler(OnAddCourse);
}

void OnAddCourse()
{
  System.Windows.Forms.MessageBox.Show("Course added");
}

[Visual Basic .NET]

The following code shows an example of wiring traverse window events in VBNet.

  Public Sub WireTraverseWindowEvents()
    'You can get app from ICommand :: OnCreate() hook parameter
    Dim editorUid As UID = New UIDClass()
    editorUid.Value = "esriEditor.Editor"
    Dim editor As IEditor = TryCast(app.FindExtensionByCLSID(editorUid), IEditor)

    'Get a reference to the traverse window
    Dim extUid As UID = New UIDClass()
    extUid.Value = "esriEditor.TraverseWindow"
    Dim traverseWindow As ITraverseWindow = TryCast(editor.FindExtension(extUid), ITraverseWindow)

    'Wire traverse window events
    AddHandler (CType(traverseWindow, ITraverseWindowEvents_Event).OnAddCourse), _
      AddressOf OnAddCourse
  End Sub

  Private Sub OnAddCourse()
    System.Windows.Forms.MessageBox.Show("Course added.")
  End Sub
