How To Suspend Calculations While a Series Of Values Are Updated?

9 Dec 2019 / 1 minute to read

You can use the property CalcEngine.CalculatingSuspended to control the calculations that will be performed as values change in your ICalcData object.

  • 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 somehow...

// Turn on calculations.

 engine.CalculatingSuspended = false;
  • 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 somehow...

' Turn on calculations.

engine.CalculatingSuspended = False
