> i belive it should look something like this
>                               case RollPoint.TopOfMonth:

> also in a separate issue, since there is no RollPoint.TopOfYear, this comment 
> in another part of the code seems wrong:
>                               //is the new file name equivalent to the 
> 'current' one
>                               //something has gone wrong if we hit this -- we 
> should only
>                               //roll over if the new file will be different 
> from the old
>                               string dateFormat = 
> m_now.ToString(m_datePattern, 
> System.Globalization.DateTimeFormatInfo.InvariantInfo);
>                               if (m_scheduledFilename.Equals(File + 
> dateFormat)) 
>                               {
>                                       ErrorHandler.Error("Compare " + 
> m_scheduledFilename + " : " + File + dateFormat);
>                                       return;
>                               }
> if the date pattern specifies only the year (rolling yearly), then i think 
> this "error" will be triggered incorrectly 11 times a year. it's fine not to 
> roll, but reporting an error is inappropriate.
