    Error writing to a file

    For each message that my application receives I write it to a log file.
    Since each message is its own thread, many time I get the error "The process
    cannot access the file "c:\bestdesk\lo g\RiskIn051707. txt" because it is
    being used by another process." Is there a way to get around this error ? I
    can do the same thing in VB6 with no problem. Thank you.

    This is how I write to the file:
    Sub ProcessEachMess age
    Dim swLog As StreamWriter

    swLog = New StreamWriter(sP ath & "\bestdesk\log\ RiskIn" &
    Date.Now.ToStri ng("MMddyy") & ".txt", True)
    swLog.Write(Now & "NEWTRADE sMessage = " & Message & vbCrLf)
    swLog.Close()
    swLog = Nothing
    :

      fliles,

      I am not sure but in Net there is the magic word flush too.

      http://msdn2.microsoft.com/en-us/lib...sh(VS.71).aspx

      Be always aware that the "Nothing" keyword is to set reference. It has
      nothing to do with the real object.

          Thanks.
          What did you mean by ""Nothing" keyword is to set reference." ?

              It does not really remove something beside the reference to it.
