Question

So I have 2 variables I.e.

Public statusId As String = String.Empty
Public orderDescription As String = String.Empty

And I want to set their values within a function, this is what I tried

Public Function GetOrderDetails(ByVal statusId As String, ByVal orderDescription As String, ByVal orderID As String, ByVal userID As String) As String

    Dim conn As New DBConnection()
    Dim sql_UserAttempts As SqlCommand = conn.SetStoredProcedure("spOrderDetailsByUserId")

    DBConnection.AddNewParameter(sql_UserAttempts, "@order_ID", ParameterDirection.Input, SqlDbType.Int, orderID)
    DBConnection.AddNewParameter(sql_UserAttempts, "@user_ID", ParameterDirection.Input, SqlDbType.Int, userID)

    Try
        conn.Open()
        Dim reader_attempts As SqlDataReader = sql_UserAttempts.ExecuteReader()
        If reader_attempts.HasRows Then
            While reader_attempts.Read()
                statusId = reader_attempts("statusId").ToString()
                orderDescription = reader_attempts("ud_orderDescription").ToString()
            End While
        End If
    Catch ex As Exception
        M1Utils.ErrorHandler(ex)
    Finally
        conn.Close()
    End Try
    Return statusId
End Function

But when I print out their values after the function they still blank so I was wondering what type of functinon i should use i.e. sub function,.. to do this ?

Called like this

            '# Retrieve Order Information
        GetOrderDetails(statusId, orderDescription, orderID, userID)

Define your function like this

Public Function GetOrderDetails(ByRef statusId As String, ByRef orderDescription As String, ByVal orderID As String, ByVal userID As String) As String
