color=#0000ff size=2>I've tried this, but I'm only getting 8192 bytes read into
the byte buffer. This seems to be the problem mentioned by Kenneth. The Read
method doesn't seem to allow the start location for the read to be set, so
looping until the entire content of the Resource is read into the buffer doesn't
seem to be an option.</FONT></SPAN></DIV>
