How To Force Calculations To Be Processed After They Have Been Suspended?

9 Dec 20191 minute to read

The following code illustrates how to force calculations to be processed after Engine.CalculatingSuspended has been flipped back to true.

  • C#
    • // Creates some data object that implements ICalcData.

this.data = new ArrayCalcData(a);



// Creates a CalcEngine object using this ICalcData object.

CalcEngine engine = new CalcEngine(this.data);



//Turn off calculations.

engine.CalculatingSuspended = true;      



// Makes multiple updates to this.data.

// Turn on calculations.

engine.CalculatingSuspended = false;



// Calls RecalculateRange so any formulas in the data can be computed.            

engine.RecalculateRange(RangeInfo.Cells(1, 1, nRows + 1, nCols + 1), data);
  • VBNET
    • ' Creates some data object that implements ICalcData.

Me.data = New ArrayCalcData(a)



' Creates a CalcEngine object using this ICalcData object.

Dim engine As New CalcEngine(Me.data)



'...



' Turn off calculations.

engine.CalculatingSuspended = True



' Makes multiple updates to this.data.

' Turn on calculations.

engine.CalculatingSuspended = False



' Calls RecalculateRange so any formulas in the data can be computed.

engine.RecalculateRange(RangeInfo.Cells(1, 1, nRows + 1, nCols + 1), Data)
