This below is the function being called:

  Public Function UICsWithInv() As List(Of uic)
        'checking to see if any inventory in database for a specific uic.  
        Dim results As New List(Of uic)()

            Dim reader As SqlDataReader
            'Dim sqlcheck As String

            ''checking to see if this item is in inventory  
            ''jls returning null - and giving error if no records.  changed to 0 if null

            '    " on a.uic=b.uic order by a.uic "

            'Me.m_Command.CommandText = sqlcheck

            Me.m_Command.CommandText = "usp_GetUICWithInventory"
            Me.m_Command.CommandType = CommandType.StoredProcedure
            Me.m_Command.Parameters.Add(New SqlParameter("@UserName", CheckNull(HttpContext.Current.Session("UserID"))))

            reader = Me.m_Command.ExecuteReader()

            While reader.Read
                Dim uicinfo As New uic()
                uicinfo.UIC = reader("uic")
                uicinfo.UICdashCommand = reader("uic") & "-" & reader("commandname")
                results.Add(uicinfo)
            End While
            reader.Close()

        Catch excpSQL As System.Data.SqlClient.SqlException
            TransactionRollback()
            Throw New Exception(excpSQL.ToString())

        Catch excpSystem As System.Exception
            TransactionRollback()
            Throw New Exception(excpSystem.ToString())

        Finally
            Me.m_Command.Parameters.Clear()

        End Try
        Return results

    End Function
