Applies to

The information in this topic applies only to the specified Visual Studio Tools for Office projects and versions of Microsoft Office.

Project type

  • Document-level projects

Microsoft Office version

  • Excel 2003

  • Excel 2007

For more information, see Features Available by Application and Project Type.

You can close the active workbook or you can specify a workbook to close.

Closing the Active Workbook

There are two procedures for closing the active workbook: one for document-level customizations and one for application-level add-ins.

To close the active workbook in a document-level customization

  • Call the Close method to close the workbook associated with the customization. To use the following code example, run it in the Sheet1 class in a document-level project for Excel.

    Globals.ThisWorkbook.Close(false, missing, missing);

To close the active workbook in an application-level add-in

  • Call the Close(Object, Object, Object) method to close the active workbook. To use the following code example, run it in the ThisAddIn class in an application-level project for Excel.

    this.Application.ActiveWorkbook.Close(false, missing, missing);

Closing a Workbook That You Specify By Name

The way that you close a workbook that you specify by name is the same for application-level add-ins and document-level customizations.

To close a workbook that you specify by name

  • Specify the workbook name as an argument to the Workbooks collection. The following code example assumes that a workbook named NewWorkbook is open in Excel.

    object fileName = "NewWorkbook.xls";
    Excel.Workbook workbook = this.Application.Workbooks.get_Item(fileName);
    workbook.Close(false, missing, missing);
