service - How to catch specific Exception in VB.NET -


vb.net 2010, framework 3.5

not catch exception identify type of error is. create error write pc's event log when event log full. sample below throws system.componentmodel.win32exception. that's great , doesn't tell me 'event log full', other errors encompassed system.componentmodel.win32exception. safe @ errorcode = -2147467259 or nativeerrorcode = 1502 determine event log full?

sub main()     try          while true ' loop overflow event log             eventlog.writeentry("source", "message")         loop      catch w system.componentmodel.win32exception         if w.errorcode = -2147467259             ' errorcode = -2147467259 when event log file full?         end if         if w.nativeerrorcode = 1502             ' nativeerrorcode = 1502 when event log file full?         end if         if w.message = "the event log file full"             ' code event log full         end if          if w.errorcode = -2147467259             if w.nativeerrorcode = 1502                 if w.message = "the event log file full"                     ' code event log full if 3 conditions true?                  end if             end if         end if     end try end sub
