Example
This example returns the error value.
//Spread for Windows Forms
FarPoint.CalcEngine.ErrorExpression err = new FarPoint.CalcEngine.ErrorExpression(FarPoint.CalcEngine.CalcError.Value);
fpSpread1.ActiveSheet.AddCustomName("Alpha", err);
fpSpread1.ActiveSheet.SetFormula(0, 0, "Alpha * 10");
FarPoint.CalcEngine.Expression expr = fpSpread1.ActiveSheet.GetCustomName("Alpha"); 
if (expr is FarPoint.CalcEngine.ErrorExpression) 
{ 
FarPoint.CalcEngine.ErrorExpression ex = ((FarPoint.CalcEngine.ErrorExpression)(expr)); 
MessageBox.Show("The error is " + ex.ErrorValue.ToString()); 
}
//Spread for Web Forms
