QueryTable.RefreshOnFileOpen Property (Excel)
True if the PivotTable cache or query table is automatically updated each time the workbook is opened. The default value is False. Read/write Boolean.
Query tables and PivotTable reports are not automatically refreshed when you open the workbook by using the Open method in Visual Basic. Use the Refresh method to refresh the data after the workbook is open.
If you import data using the object model, data from a Web query or a text query must be imported as a QueryTable, while all other external data can be imported as either a ListObject or a QueryTable.
You can use the QueryTable property of the ListObject to access the RefreshOnFileOpen property.
