Use this method to create a new CustomTaskPane that is associated with the active window of the Microsoft Office application.

Although a CustomTaskPaneCollection object is a collection of CustomTaskPane objects, the Add method accepts UserControl objects instead of CustomTaskPane objects. For more information, see Custom Task Panes.

If you want to specify a particular window and associate the custom task pane with it, use the Add(UserControl, String, Object) method.

The following code example demonstrates how to create a custom task pane by using the Add(UserControl, String) method. The example also uses properties of the CustomTaskPane object to modify the default appearance of the custom task pane. This code example is part of a larger example provided for CustomTaskPane.

private MyUserControl myUserControl1;
private Microsoft.Office.Tools.CustomTaskPane myCustomTaskPane;

private void ThisAddIn_Startup(object sender, System.EventArgs e)
    myUserControl1 = new MyUserControl();
    myCustomTaskPane = this.CustomTaskPanes.Add(myUserControl1,
        "New Task Pane");

    myCustomTaskPane.DockPosition =
    myCustomTaskPane.Height = 500;
    myCustomTaskPane.Width = 500;

    myCustomTaskPane.DockPosition =
    myCustomTaskPane.Width = 300;

    myCustomTaskPane.Visible = true;
    myCustomTaskPane.DockPositionChanged +=
        new EventHandler(myCustomTaskPane_DockPositionChanged);
