check if excel sheet in manual calc mode
 

Can we check all the time if excel sheet in manual calc mode
I have tried :
Function MyCalcStatus()
Application.Volatile
If Application.Calculation = -4105 Then MyCalcStatus = "Auto"
If Application.Calculation = -4135 Then MyCalcStatus = "Manual"
End Function

But because nothing in the sheet get calculated in Manual mode the Volatile
does not get triggerd either.
