Re: StreamWriter Truncating Output

Sorry folks but I should have waited a bit before sending this.  I figured
this one out - you need to set the AutoFlush to TRUE for the StreamWriter
object.  So,

sw.AutoFlush = true;
... fixed the problem.  I tried to use a counter and manually sw.flush()
every x number of reads but that does seem to work, even when I set the
iteration to 10.  Anyway, the AutoFlush works fine even if it does have a
bit more overhead.
