No, I have no sample code. The only avalible code I know of, is listed on these two pages: http://trac.osgeo.org/mapguide/wiki/CodeSamples http://trac.osgeo.org/mapguide/wiki/maestro/MaestroAPI

Hi, Thanks again. Can u tell me the sample application for Runtime map ( sample code) so that i can learn it and i will convert it for oracle conversion Thanks and Regards, Padmini. Kenneth Skovhede, GEOGRAF A/S wrote:In that case, you will do something different. You need to setup the layer to display all points correctly. Use Studio or Maestro to accomplish this. When the user needs to view the layer, you do this: 1. Get a copy of the LayerDefinition2. Modify the "FILTER" property of the LayerDefinition to display only the required data, eg: "ID > 500 AND ID < 510".3. Save the copy in the session repository under a random name. 4. Get the runtime map, and either 5a. Replace the resourceId of an existing layer with the one from step 3, or5b. Insert a new layer into the runtime map, pointing to the temporary layerdefinition from step 36. Make sure the layer from step 5 is visible 7. Save the modified runtime map 8. Refresh the client.If your map already contains the layer to be show, choose 5a, otherwise choose 5b.Regards, Kenneth Skovhede, GEOGRAF A/S padmini godavarthi skrev:Hi, Thank u very much for u r reply. I will check it out . My Doubt is that 1) If i create a package in mapguide maestro , connecing to the oracle how can access the data using queries. suppose i create a feature resource for a table data in oracle after that i followed all the procedure and created a package successfully. If user wants to query this table and wants to display only some of the features on the map dynamically .How can i provide this? If u know this plz help me Regards, Padmini. Kenneth Skovhede, GEOGRAF A/S wrote:There is not much I can say to help you there.It is very difficult to create LayerDefinitions and WebLayouts programatically.The problem with creating a LayerDefinition is the number of properties you have to set. Such properties include, scalerange, point styles, rules, fonts, linewidth, colors, etc.The WebLayout has all the buttons and menu items. I would recommend you reconsider alternatives. To create a new LayerDefinition, simply do: Dim layerdefinition as new MaestroAPI.LayerDefinition() You can use the same approach for any of the other items. Then you can save it as you like, using con.SaveResourceAs(...). There is no help anywhere, that explains what properties to set.You can look in the Maestro code, or examine the Sheboygan LayerDefinitions to see what happens.A simple shortcut, would be to create a "template" from Maestro, and then use that template when you start out. You can then modify the template,and save it as a resource. To produce a "template", simply create a new LayerDefinition in Maestro, and then click the "Edit Xml". Copy-n-paste the Xml to a file (say C:\template.xml).To load a template as an object, you can use (C# code, can never remember generics in VB):MaestroAPI.LayerDefinition layerdefinition; using(System.IO.FileStream fs = System.IO.File.OpenRead("C:\\template.xml")) layerdefintion = con.DeserializeObject<MaestroAPI.LayerDefinition>(fs);You can then modify the geometry column, featuresource pointer, columns, filter, tooltip and other items, until it fits the newly uploaded SHP file. As I said, it will be dificult, and there is no help avalible for the task. Your primary tool is the error log:C:\program files\mapguideopensource2.0\server\logs\error.log Good luck. Regards, Kenneth Skovhede, GEOGRAF A/S padmini godavarthi skrev:Hi, Thanks .its working fine now. To build a map, you must have all the components: 1. FeatureSource, references data 2. LayerDefinition, references a FeatureSource 3. MapDefinition, references multiple LayerDefinitions 4. WebLayout, references a MapDefinitionAll these items must be in a repository (either Library or Session)I know the procedure to create it in mapguide maestro. 1) Now my problem was i want to create ALL the above items programmetically (my input is only a shape file) byusing maestro dll. If u know this plz help me Regards, Padmini.

Inside, it references layers, which references featuresources, as described above. It is very slow to do this, so when you open a map in the browser, the xml is transformed into a binary object. This object contains all the info from the MapDefinition and some info from the layers and featuresources.You need to know this, because if you try to toggle layervisibility in the MapDefinition, nothing happens. In short, the Runtime Mapisa binary object that you can manipulate using the MapGuide (and Maestro)-API, and it only works for a displayed map. Upon startup, the Runtime Map is identical to the MapDefinition it was created from.A short example of using an existing WebLayout:Dim host As New Uri("http://localhost/mapguide/mapagent/mapagent.fcgi";)Dim conn As New HttpServerConnection(host, "Administrator","admin", "en", True)'You have to change the string below to point at a valid WebLayoutDim weblayout as WebLayout =con.GetWebLayout("Library://mylayout.WebLayout") Dim mapdefinition as MapDefinition = con.GetMapDefinition(weblayout.Map.ResourceId)weblayout.Map.InitialView = new MapViewType() weblayout.Map.InitialView.Scale = 2000 'Zoom to 1:2000 weblayout.Map.InitialView.CenterX = (mapdefinition.Extents.MaxX - mapdefinition.Extents.MinX) + mapdefinition.Extents.MinX weblayout.Map.InitialView.CenterY = (mapdefinition.Extents.MaxY -mapdefinition.Extents.MinX) + mapdefinition.Extents.MinY Dimtempid as ResourceIdentifier = new ResourceIdentifier(Guid.NewGuid(), OSGeo.MapGuide.MaestroAPI.ResourceTypes.WebLayout, con.SessionID) Response.Redirect("/mapguide/ajaxviewer/?WEBLAYOUT=" &Server.UrlEncode(tempid) & "&USERNAME=Anonymous&PASSWORD=") Regards, Kenneth Skovhede, GEOGRAF A/Spadmini godavarthi skrev:Hi, Thanks for u r reply actually i wrote the code as Dim host As New Uri("http://localhost/mapguide/mapagent/mapagent.fcgi";) Dim conn As New HttpServerConnection(host,"Administrator", "admin", "en", True) Dim res As New ResourceIdentifier("Filebased data/Maps/mapdata",ResourceTypes.MapDefinition) Dim mapId As String = res.ResourceId with that i got the map resource id.
