Workbook.UpdateFromFile Method (2007 System)
Updates a read-only workbook from the saved disk version of the workbook if the disk version is more recent than the copy of the workbook that is loaded in memory. If the disk copy has not changed since the workbook was loaded, the in-memory copy of the workbook is not reloaded.
Assembly: Microsoft.Office.Tools.Excel.v9.0 (in Microsoft.Office.Tools.Excel.v9.0.dll)
This method is useful when a workbook is opened as read-only by user A and opened as read/write by user B. If user B saves a newer version of the workbook to disk while user A still has the workbook open, user A cannot get the updated copy without closing and reopening the workbook and losing view settings. The method updates the in-memory copy of the workbook from the disk file.
