Question

In my database one user can have multiple order. i want to get all orders for a user and save it in a list.

this is what i’m doing now

Public Function GetUserOrders(ByVal userID As Integer) As DataSet
        Dim sqlDA As New SqlDataAdapter
        Dim ds As New DataSet
        Dim myCommand As New Data.SqlClient.SqlCommand("sp_GetUserOrders", myConnection)
        ' Mark the Command as a SPROC
        myCommand.CommandType = CommandType.StoredProcedure
        Dim muserID As New SqlParameter("@userID", SqlDbType.Int)
        muserID.Value = userID
        myCommand.Parameters.Add(muserID)
        Try
            ' Open the connection and execute the Command
            myConnection.Open()
            sqlDA.SelectCommand = myCommand
            sqlDA.Fill(ds)

        Catch ex As Exception

        Finally
            myConnection.Close()
        End Try

        Return ds
    End Function

but i can’t seem to figure out how to assign the results to a list.

Dim orderList As New ListItemCollection()
orderlist = GetUserOrders()

does not work, please help.

Answer 1

i got it.

i set the list inside the getuserorders function.

Dim dr As SqlDataReader
        Dim orderList As New ListItemCollection()
        Try
            ' Execute the command
            myConnection.Open()
            dr = myCommand.ExecuteReader()

            If Not dr.Read() Then
                Return Nothing
            Else
                While dr.Read()
                    orderList .Add(dr("orderCode"))
                End While
            End If
            dr.Close()
        Finally
            myConnection.Close()
        End Try
