Server.MapPath and ASP.Net

[hpl]

I have this code:

Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=C:\unzipped\exceldotnet[1]\exceltest.xls;" & _
"Extended Properties=Excel 8.0;"

which works fine. I have copied the .xls-file to my project folder and tries this code:

Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & server.mappath("exceltest.xls") & ";" & _
"Extended Properties=Excel 8.0;"

But then I receive an error saying:

The Microsoft Jet database engine cannot open the file ''. It is already opened exclusively by another user, or you need permission to view its data.

What's wrong, can't I use the server.mappath?

Make sure the asp.net account has access to the directory containing the .mdb file.

You're right, I'd forgot! Thanks

Hi again, I have problems with Server.MapPath in a class. The intellisense wouldn't recognize server.mappath. Am I doing something wrong or do I need to specify a namespace? Here is my code:

Imports System.Data
Imports System.Data.OleDb
Public Class clsMedieroer : Inherits clsMateriale
    Private _medie As Integer
    Private _medie1 As Integer
    Private _dimension As Integer

    Sub New(ByVal s As Integer, ByVal m As String)
        ' konstruktøren skaber et materiale med s 
        ' (sker ved at kalde klassens metode Medie med s som parameter)
        MyBase.New(m)
        Medie = s
    End Sub

    Public Sub FindMedie()
        Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
        "Data Source=" & server.mappath("exceltest.xls") & ";" & _
        "Extended Properties=Excel 8.0;"

        Dim strSql As String = "SELECT * FROM [Sheet1$] WHERE Id=4"

        Dim objConnection As New OleDbConnection(strConn)
        Dim objCommand As New OleDbCommand(strSql, objConnection)
        Dim objDataReader As OleDbDataReader

        objConnection.Open()
        objDataReader = objCommand.ExecuteReader()

        Do While objDataReader.Read() = True
            _dimension = CInt(objDataReader("pris"))
        Loop
        objDataReader.Close()
        objConnection.Close()

        Select Case _medieroer
            Case Is = "St. 37.0 Konti"
                _medie1 = 15
            Case Else
                _medie1 = _medie
        End Select
    End Sub

    Public ReadOnly Property Medie1() As Integer
        ' returnerer værdien af materialet, der læses fra
        Get
            Return _medie1
        End Get
    End Property

    Public ReadOnly Property Dimension() As Integer
        ' returnerer værdien af materialet, der læses fra
        Get
            Return _dimension
        End Get
    End Property

    Public WriteOnly Property Medie() As Integer
        ' definerer værdien af materialet
        Set(ByVal Value As Integer)
            _medie = Value
            FindMedie()
        End Set
    End Property

End Class

I've tried typing
Imports system.web
but it still doesn't work
