Question : How to set the calculation mode to manual in Excel 2007

I use Application.Calculation to set the calculation mode to manual. However, this seems to affect all workbooks and not just the active workbook.

Answer : How to set the calculation mode to manual in Excel 2007

The Calculation property is a member of the Application object. Therefore, the calculation mode affects all workbooks. You cannot set the calculation mode for only one workbook. Excel 2000 and later versions provide a new Worksheet object property: EnableCalculation. When this property is False, the worksheet will not be calculated, even if the user requests a calculation. Setting the property to True will cause the sheet to be calculated.
