To add a custom task pane to an application

  1. Open or create an application-level project for one of the applications listed above. For more information, see How to: Create Office Projects in Visual Studio.

  2. On the Project menu, click Add User Control.

  3. In the Add New Item dialog box, change the name of the new user control to MyUserControl, and then click Add.

    The user control opens in the designer.

  4. Add one or more Windows Forms controls from the Toolbox to the user control.

  5. Open the ThisAddIn.cs or ThisAddIn.vb code file.

  6. Add the following code to the ThisAddIn class. This code declares instances of MyUserControl and CustomTaskPane as members of the ThisAddIn class.

    
    private MyUserControl myUserControl1;
    private Microsoft.Office.Tools.CustomTaskPane myCustomTaskPane;
    
    
    
  7. Add the following code to the ThisAddIn_Startup event handler. This code creates a new CustomTaskPane by adding the MyUserControl object to the CustomTaskPanes collection. The code also displays the task pane.

    
    myUserControl1 = new MyUserControl();
    myCustomTaskPane = this.CustomTaskPanes.Add(myUserControl1, "My Task Pane");
    myCustomTaskPane.Visible = true;
    
    
    
    NoteNote

    This code associates your custom task pane with the active window in the application. For some applications, you might want to modify this code to ensure that the task pane appears with other documents or items in the application. For more information, see Managing Custom Task Panes in Multiple Application Windows.
