Private Sub DisplayWhenActivated()
    Me.Range("A1", "A5").Value2 = 22
    Me.Range("B1", "B5").Value2 = 55

    ActivateChart = Me.Controls.AddChart(Me.Range("D2", "H12"), _
        "ActivateChart")
    ActivateChart.SetSourceData(Me.Range("A1", "B5"), _
        Excel.XlRowCol.xlColumns)
    ActivateChart.ChartType = Excel.XlChartType.xl3DColumn
End Sub 

Sub ActivateChart_ActivateEvent() Handles ActivateChart.ActivateEvent
    MsgBox("The chart was activated.")
End Sub
private void DisplayWhenActivated()
{
    this.Range["A1", "A5"].Value2 = 22;
    this.Range["B1", "B5"].Value2 = 55;

    Microsoft.Office.Tools.Excel.Chart chart1 =
        this.Controls.AddChart(this.Range["D2", "H12"], 
        "chart1");

        Excel.XlRowCol.xlColumns);
    chart1.ChartType = Excel.XlChartType.xl3DColumn;
