6. Next, select the User Control, and name it UserControl1.cs.
7. 
7. Open the UserControl1.cs file, and add the following namespace references:

   using System.Windows.Forms;
   using Office = Microsoft.Office.Core;
   using PowerPoint = Microsoft.Office.Interop.PowerPoint;

8. Open the Ribbon1.cs fi le, and add the following namespace references:

   using System.Windows.Forms;
   using Office = Microsoft.Office.Core;
   using PowerPoint = Microsoft.Office.Interop.PowerPoint;
   

9. Next, add the instance of the User Control and custom task pane to the Ribbon code file:

   // Usercontrol instance to access from the Ribbon
   private UserControl1 PacktUserControl;
   // Instance for Custom Task Pane to create
   private Microsoft.Office.Tools.CustomTaskPane PacktCustomPane;
   

10. Next, write the following code to show the custom task pane in the button click event of the Ribbon menu:

    private void RibbonButton1_Click(object sender, 
    RibbonControlEventArgs e)
    {
    // Initializing the UserControl in the ribbon
    PacktUserControl = new UserControl1();
    // Add the UserControl to the custom task pane
    PacktCustomPane = Globals.ThisAddIn.CustomTaskPanes.
    Add(PacktUserControl, "Calendar");
    // Set the custom task pane to visible
    PacktCustomPane.Visible = true;
    }
    

11. On the ValueChanged event of the dateTimePicker , we are writing the code to insert the selected date.

    private void dateTimePicker1_ValueChanged(object sender, 
    EventArgs e)
    {
    try
    {
    // Getting the active presentation slide
    PowerPoint.Slide PckTSlide = Globals.ThisAddIn.
    Application.ActivePresentation.Slides[1];
    // Set the presentation type like text or image imsert option
    PacktTextShape = PckTSlide.Shapes.AddTextbox(Office.
    MsoTextOrientation.msoTextOrientationHorizontal,
    50, 100, 600, 50);
    // Set the text value as selected date time
    PacktTextShape.TextFrame.TextRange.Text = dateTimePicker1.
    Value.ToString();
    // Font style properties
    PacktTextShape.TextFrame.TextRange.Font.Size = 48;
    PacktTextShape.TextFrame.TextRange.Font.Color.RGB = Color.
    DarkViolet.ToArgb();
    }
    catch (Exception ex)
    {
    MessageBox.Show(ex.ToString());
    }
    }
