I prepared XLL Addin with Addin Express. Than i try to export to Excel from Windows Forms application (look below code)

This is C# Windows Forms Code: 


Excel.Application excelApp=new Excel.ApplicationClass();
excelApp.Visible = true;
excelApp.UserControl = true;
workbook = (Excel._Workbook)(excelApp.Workbooks.Add(Missing.Value));(Excel._Worksheet)workbook.ActiveSheet.GetRange("A1","A2").Formula="=MyCustomFunction(25)";


When i open new Excel document like above , (although i can see my xll in addins list) i couldnt access UDF(in xll) from excel the code opened.

Hi Ted.

Do you see the add-in in the Add-ins dialog of Excel? Is it checked?

Hi Ted.

Please try to call the Calculate method of the range after you add a new formula.
