Public Sub ShowSqlException(ByVal connectionString As String)
    Dim queryString As String = "EXECUTE NonExistantStoredProcedure"
    Dim errorMessages As New StringBuilder()

    Using connection As New SqlConnection(connectionString)
        Dim command As New SqlCommand(queryString, connection)

        Try
            command.Connection.Open()
            command.ExecuteNonQuery()

        Catch ex As SqlException
            Dim i As Integer
            For i = 0 To ex.Errors.Count - 1
                errorMessages.Append("Index #" & i.ToString() & ControlChars.NewLine _
                    & "Message: " & ex.Errors(i).Message & ControlChars.NewLine _
