Example
This example creates a new expression with a binary operator applied to a pair of operands.
FarPoint.CalcEngine.Expression arg1 = new FarPoint.CalcEngine.DoubleExpression(1.0);
FarPoint.CalcEngine.Expression arg2 = new FarPoint.CalcEngine.DoubleExpression(2.0);
FarPoint.CalcEngine.Expression oneplustwo = new FarPoint.CalcEngine.BinaryOperatorExpression(FarPoint.CalcEngine.BinaryOperatorInfo.AddOperator,arg1, arg2);
//Spread for Windows Forms
((FarPoint.Win.Spread.Model.IExpressionSupport)fpSpread1.ActiveSheet.Models.Data).SetExpression(0, 0, oneplustwo);
//Spread for Web Forms
((FarPoint.Web.Spread.Model.IExpressionSupport)FpSpread1.Sheets[0].DataModel).SetExpression(0, 0, oneplustwo);
Dim arg1 As FarPoint.CalcEngine.Expression
Dim arg2 As FarPoint.CalcEngine.Expression
Dim oneplustwo As FarPoint.CalcEngine.Expression
arg1 = New FarPoint.CalcEngine.DoubleExpression(1.0)
arg2 = New FarPoint.CalcEngine.DoubleExpression(2.0)
oneplustwo = New FarPoint.CalcEngine.BinaryOperatorExpression(FarPoint.CalcEngine.BinaryOperatorInfo.AddOperator, arg1, arg2)
'Spread for Windows Forms
CType(FpSpread1.ActiveSheet.Models.Data, FarPoint.Win.Spread.Model.IExpressionSupport).SetExpression(0, 0, oneplustwo)
'Spread for Web Forms
CType(FpSpread1.Sheets(0).DataModel, FarPoint.Web.Spread.Model.IExpressionSupport).SetExpression(0, 0, oneplustwo)
