Thanks Kenneth. This does explain what I'm seeing. I have tried MgByteSink, but am having the same problem with it. Keith

The MgByteReader is very volatile and fragile, when you try to debug it with VS. Any attempt to pass the byte reader to a function (as a parameter) will clear the stream. You cannot read more than 8kb out of the stream in a single Read() operation, making it a royal pain to use the MgByteReader. I have seen others using an MgByteSink, but I have yet to try that. Regards, Kenneth, GEOGRAF A/S Campbell, Keith A skrev: I am trying to alter a map definition through the API and cannot get the contents of the MgByteReader in string format. 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.
