I'm using 1.1.0, so maybe that is where the problem is. ________________________________

I have been using this code to read data from the server: XmlDocument doc = new XmlDocument(); { MgByteReader rd = rs.GetResourceContent(new MgResourceIdentifier(webLayout)); using(System.IO.MemoryStream ms = new System.IO.MemoryStream()) { byte[] buf = new byte[1024]; int c = 0; do { c = rd.Read(buf, buf.Length); ms.Write(buf, 0, c); } while (c != 0); ms.Position = 0; doc.Load(ms); } } It worked the last time I used it, but that was a while ago (around 1.2 beta 1, I think). Regards, Kenneth, GEOGRAF A/S Campbell, Keith A skrev: Kenneth, If I run this code, it results in an endless loop because the read = mapByteRdr.Read(buf, buf.length); call reads the same data each time - the start point for each read is not advanced.

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. Presumably somebody must have found a way around this.

Here's the code:- String mapDefinition = "Library://My Folder/Maps/My Map.MapDefinition"; MgResourceIdentifier MapResID = new MgResourceIdentifier(mapDefinition); MgByteReader mapByteRdr = res.GetResourceContent(MapResID);//res is instantiated Resource Service. XmlDocument doc = new XmlDocument(); doc.LoadXml(mapByteRdr.ToString()); LoadXML fails with an error ' Root element is missing'. I can copy the contents of mapByteRdr from Visual Studio at runtime and it contains properly formatted XML for the map definition. If I use the ToFile() method, the resultant file is empty. I cannot see why these two methods do not return the xml string in the reader. Any help is welcome. Cheers, Keith This email and any attached files are confidential and copyright protected.
