Very odd.<br>
<br>
I have been using this code to read data from the server:<br>
<br>
<tt>XmlDocument doc = new XmlDocument();<br>
{ <br>
MgByteReader rd = rs.GetResourceContent(new
MgResourceIdentifier(webLayout));<br>
using(System.IO.MemoryStream ms = new System.IO.MemoryStream())<br>
{<br>
byte[] buf = new byte[1024];<br>
int c = 0;<br>
do<br>
{<br>
c = rd.Read(buf, buf.Length);<br>
ms.Write(buf, 0, c);<br>
} while (c != 0);<br>
ms.Position = 0;<br>
doc.Load(ms);<br>
}<br>
}</tt><br>
<br>
It worked the last time I used it, but that was a while ago (around 1.2
beta 1, I think).<br>

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>
