Flushing a stream

[kejpa]

Hi,

I want to make sure that my trace.Writeline's are properly written to my trace file and so I created a Threading.Timer like...

_trdStreamFlusher = New Threading.Timer(AddressOf StreamFlusher, _Stream, 10000, 10000)

' -Snip-
   Private Shared Sub StreamFlusher(ByVal file As Object)
       Dim oStream As IO.FileStream = DirectCast(file, IO.FileStream)
       Try
           oStream.Flush()
       Catch ex As Exception
           Console.WriteLine(ex.Message)
       End Try
   End Sub

but the file don't contain all my trace information :(

 

Any ideas?

TIA

Could you not either just call flush when you add data to the stream or alternatively one of the overloads for the FileStream's constructor allows you to specify the buffer size so you could choose a more appropriate value.

 

Also IIRC instance members of the FileStream object are not thread safe - therefore you could hit a race condition if the timer fires at the same time as you are adding data to the stream.
