 While trying to get rendered map using:

 {{{
 Dim host As New Uri("http://server/mapguide2009/mapagent/mapagent.fcgi")
         Dim conn As New HttpServerConnection(host, "Administrator",
 "password", "en", True)

         Dim mapId As String =
 conn.GetResourceIdentifier("Folder/SubFolder/PLAN",
 ResourceTypes.MapDefinition, False)
         Dim mapDef As MapDefinition = conn.GetMapDefinition(mapId)
         Dim mapName As String = conn.GetResourceName(mapId, False)

         Dim rtMapId As String = "Session:" + conn.SessionID + "//" +
 mapName + ".Map"
         conn.CreateRuntimeMap(rtMapId, mapDef)
         Dim rtMap As RuntimeClasses.RuntimeMap =
 conn.GetRuntimeMap(rtMapId)

         Dim stream As System.IO.MemoryStream =
 conn.RenderRuntimeMap(rtMapId, 6259416.4634, 4320081.3816, 10000, 400,
 400, 75)
 }}}

 Here, on conn.RenderRuntimeMap (last line) it throws following exception:

 {{{

 ...instead of returning rendered Stream.
