How about

Dim time As DateTime = DateTime.Now
    Dim j As Integer
    For j = 0 To 11
        DDL.Items.Add((time.AddMonths(j)).ToString("MMMM"))
    Next

If your just trying to convert the integer value to month name an easy way to do it would be just to create an array of strings containing the month names and use your j value as the index.

Dim time As DateTime = DateTime.Now
DDL.Items.Clear()
While time <= time.AddYears(1)
    DDL.Items.Add((time.AddMonths(j)).ToString("MMMM yyyy"))
    time = time.AddMonths(1)
