RE: [mapguide-users] Add new layer to map

[Mark Pendergraft]

Are you trying to add permanent layers to the map?

Does this need to happen at runtime?

I don't understand what you mean.
Changes to the runtime map does not go into MGStudio.
Only changes to the MapDefinition xml can be seen there.

Dear Kenneth,
I need your help for a second problem:
 
I apparently save successfully the new layer into library repository
(the
legend and the map are correctly updated, and from MGStudio the new
layer is
visible in layers list), but in MGStudio 'Layer by group' view, my layer
doesn't appear, so that when I reload the map, the new layer is lost
(but
it's present in MGStudio).
 
Have you some idea?
Thanks, Fabio

                Dear all,
                I need to add a layer to my map from XML definition.
                 
                This is my code:
                 
                    Public Sub CreateLater(ByVal sessionID As String,
ByVal mapName As
                String, _
                                                   ByVal newLayerName As
String, ByVal
                groupName As String)
                 
                        Dim userInfo As New MgUserInformation
                        userInfo.SetMgSessionId(sessionID)
                 
                        Dim siteConn As New MgSiteConnection
                        siteConn.Open(userInfo)
                 
                        Dim resourceSrvc As MgResourceService =
                siteConn.CreateService(MgServiceType.ResourceService)
                        Dim map As New MgMap()
                        map.Open(resourceSrvc, mapName)
                 
                        'Loading XML layer
                        Dim newLayerXML As New XmlDocument
                        newLayerXML.Load(Me.MapPath("NewLayer.xml"))
                 
                        'Saving new layer in session repository
                        Dim byteSource As New
        
MgByteSource(Encoding.UTF8.GetBytes(newLayerXML.OuterXml),
                newLayerXML.OuterXml.Length)
                        byteSource.SetMimeType(MgMimeType.Xml)
                        Dim resID As New MgResourceIdentifier("Session:"
& sessionID &
                "//" & newLayerName & "." &
MgResourceType.LayerDefinition)
                        resourceSrvc.SetResource(resID,
byteSource.GetReader(), Nothing)
                        Dim newLayer As New MgLayerBase(resID,
resourceSrvc)
                 
                        'Add new layer to group
                        Dim layerGroup As MgLayerGroup = Nothing
                        If map.GetLayerGroups().Contains(groupName) Then
                            layerGroup =
map.GetLayerGroups.GetItem(groupName)
                        Else
                            layerGroup = New MgLayerGroup(groupName)
                            layerGroup.SetVisible(True)
                            layerGroup.SetDisplayInLegend(True)
                            layerGroup.SetLegendLabel(groupName)
                            map.GetLayerGroups.Add(layerGroup)
                        End If
                        newLayer.SetGroup(layerGroup)
                 
                        'Insert new layer to map
                        newLayer.SetName(newLayerName)
                        newLayer.SetVisible(True)
                        newLayer.SetLegendLabel(newLayerName)
                        newLayer.SetDisplayInLegend(True)
                        map.GetLayers.Insert(0, newLayer)
                 
                        map.Save(resourceSrvc)
                 
                Saving the map, an MgNotImplementedException occurs.
                 
                Where is my mistake?
                 
                Thanks in advance for your help.
