Error while openning connection

[Killgore]

Hi everyone. I am having this error message

"Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

when i am openning the connection on an Access database when trying to populate a combo box. I have tried it locally and on one of the network drive. Here is my code :

Private Sub frmPrintSearch_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim Cmd As OleDb.OleDbCommand
        Dim Conn As OleDb.OleDbConnection
        Dim Sql As String = Nothing
        Dim Reader As OleDb.OleDbDataReader
        Dim ComboRow As Integer = -1
        Dim Columns As Integer = 0
        Dim Category As String = Nothing

        cmbType.Items.Clear()
        Conn = New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=N:\Supply\Admininstration and Management\temp\unss.mdb")
        Sql = " Select PrintAccType FROM DropDownList Order By PrintAccType Asc"
        Cmd = New OleDb.OleDbCommand(Sql, Conn)
        Try
            Conn.Open()
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
        Reader = Cmd.ExecuteReader()
        While Reader.Read()
            For Columns = 0 To Reader.FieldCount - 1
                Category = Reader.Item(Columns)
            Next
            cmbType.Items.Add(Category)
            ComboRow += 1
        End While
        Conn.Close()
    End Sub

Can anyone help me please

So you're saying that you get the same error message when trying to access an MDB file on your local machine?

are you running your project from a location that is not trusted, such as a network share?
