Question

I want to use excel function in Visual Basic 2010 Express. I tried to search in the internet to see how to do that.

I come across with this solution:

Module Module1

    Sub Main()
        Imports Excel = Microsoft.Office.Interop.Excel

        Dim oXLApp As New Excel.Application
        Dim ExcelMath As Excel.WorksheetFunction
        ExcelMath = New Excel.WorksheetFunction

        Dim I As Double
        Dim s As Double

        I = ExcelMath.Average(1, 2, 3, 4, 5)
        s = ExcelMath.StDev(1, 2, 3, 4, 5)
        ExcelMath = Nothing
        oXLApp.Quit()
        oXLApp = Nothing

    End Sub

End Module

However, there is error of:
1. Syntax error.
2. Type ‘Excel.Applciation” is not defined.
3. Type ‘Excel.WorksheetFunction’ is not defined.

How should it be resolved?

Or is there other simple way to do that?

Thanks a lot!

My guess is that you need to add a reference to the Microsoft Excel Object Library. For a brief tutorial, see http://support.microsoft.com/kb/301982 (more specifically, step #3).

If this doesn’t resolve the problem, let us know.
