You can save a new workbook by using the Workbook object's SaveAs method and specifying the name of the workbook you want to save. If a workbook by that name already exists, an error occurs. When a workbook has been saved by using the SaveAs method, additional changes are saved by using the Workbook object's Save method. You can also save a copy of an existing workbook with a different file name by using the SaveCopyAs method. You can supply a file name to be used with the SaveAs or SaveCopyAs method, or you can use the Application object's GetSaveAsFileName method to let the user supply the name to be used to save the workbook. If the user clicks Cancel in the Save As dialog box, the GetSaveAsFileName method returns False.
