Remarks

Microsoft Office applications do not provide a default UI for users to display custom task panes.

For more information, see Custom Task Panes.

Examples

The following code example creates a custom task pane and displays it. This code example is part of a larger example provided for CustomTaskPane.

Private myUserControl1 As MyUserControl
Private WithEvents myCustomTaskPane As Microsoft.Office.Tools.CustomTaskPane

Private Sub ThisAddIn_Startup(ByVal sender As Object, ByVal e As System.EventArgs) _
    Handles Me.Startup

    myUserControl1 = New MyUserControl()
    myCustomTaskPane = Me.CustomTaskPanes.Add(myUserControl1, "New Task Pane")

    With myCustomTaskPane
        .DockPosition = Office.MsoCTPDockPosition.msoCTPDockPositionFloating
        .Height = 500
        .Width = 500
        .DockPosition = Office.MsoCTPDockPosition.msoCTPDockPositionRight
        .Width = 300
        .Visible = True 
    End With 
End Sub

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 =
        Office.MsoCTPDockPosition.msoCTPDockPositionFloating;
    myCustomTaskPane.Height = 500;
    myCustomTaskPane.Width = 500;

    myCustomTaskPane.DockPosition =
        Office.MsoCTPDockPosition.msoCTPDockPositionRight;
    myCustomTaskPane.Width = 300;

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