Thank's Kenneth, I think the error I keep getting is that the runtime map does not exist yet?
Code fragments: =============== The viewer is activated at the bottom of the code by the following: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>TEST</title> </head> <frameset > <frame id="viewerFrame" frameborder="no" marginwidth="0" marginheight="0" scrolling="no" src="http://localhost/mapguide/mapviewernet/ajaxviewer.aspx?SESSION=<%=sessionId%>&WEBLAYOUT=<%=sesslayout%>"> </frameset> I created the map via: Dim map As MgMap = New MgMap map.Create(resourceSrvc, mapid, "DemoMap") ' mapid is the resource identifier for the map definition Dim layers = map.GetLayers() Because I kept getting an error when I tried to open the map... Further down (after setting up the layer definition) I add it to the map: 'Create the layer definition layerDefContent = BuildLayerDefinitionContent(mrkrDataS, featureName, "") Dim rnull As MgByteReader resourceSrvc.SetResource(mrkrLD_ID, layerDefContent, rnull) Dim mylegendName = MgLocalizer.GetString("MARKERLAYER", locale) Dim layer = New MgLayer(mrkrLD_ID, resourceSrvc) layer.SetDisplayInLegend(True) layer.SetLegendLabel(mylegendName) layers.Insert(0, layer) 'create a feature representing this segment and insert it into the data source Dim mrkrProps = New MgPropertyCollection Dim TipProp = New MgStringProperty("TXTDISP", "") mrkrProps.Add(TipProp) Dim URLProp = New MgStringProperty("URLLINK", "") mrkrProps.Add(URLProp) Dim agf = New MgAgfReaderWriter() Dim geomReader = agf.Write(geom) Dim ngeomProp = New MgGeometryProperty("GEOM", geomReader) mrkrProps.Add(ngeomProp) Dim cmd As MgInsertFeatures = New MgInsertFeatures("Marker", CType(mrkrProps, MgPropertyCollection)) Dim commands = New MgFeatureCommandCollection() commands.Add(cmd) featureSrvc.UpdateFeatures(mrkrDS_ID, commands, False) The feature insertion works since I extracted the session SDF to check. After that the code simply extracts the weblayout, changes the starting center x, y and sets a session weblayout. One way I managed to get this work is have the add marker code be run in a hidden frame AFTER the map has been loaded in the main frame. But is there a better way?
