The only way around it, that I have found, is to copy/paste code like
this:<br>
<br>
System.IO.MemoryStream ms = new System.IO.MemoryStream();<br>
byte[] buf = new byte[8*1024];<br>
int read = 1;<br>
while(read != 0)<br>
{<br>
read = <font face="Courier New" size="2"><span
defanghtml_style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'">mapByteRdr.Read(buf,
buf.length);<br>
ms.Write(buf, 0, read);<br>
</span></font>}<br>
<br>
//ms now contains the stream<br>

start location for the read to be set, so looping until the entire

option.</font></span></div>
