[mapguide-users] RES: Modify the map definition and web layout flexible definition of a session

[liglio.pessoal at nexxa.com.br]

Hi Gordon,

 

This is part of a code. I have Session and MapName and I can’t read the map object of a session. 

 

public class UtilMap : IDisposable 

 

    private string strSessionMap;

    private string strMapDefinition;

    private MgSiteConnection siteConnection;

    private MgUserInformation userInfo;

    private MgFeatureService featureService;

    private MgResourceService resourceService;

    private MgMap map;

    private string mapName;

    private string strTempLayerSufix;

 

    /// <summary>

    /// Constructor of class to manipulate the RunTime Mapguide Map 

    /// </summary>

    /// <param name="pstrSessionMap">Map Session ID</param>

    /// <param name="pstrMapDefinition">Map Library Definition</param>

    public UtilMap(string pstrSessionMap, string pstrMapDefinition)

    {

        try

        {

            this.strSessionMap = pstrSessionMap;

            this.strMapDefinition = pstrMapDefinition;

            this.strTempLayerSufix = "-" + strSessionMap;

 

            this.siteConnection = new MgSiteConnection();

            this.userInfo = new MgUserInformation(this.strSessionMap);

 

            try

            {

                this.siteConnection.Open(this.userInfo);

            }

            catch (Exception ex)

            {

                throw new Exception("Erro UtilMap SiteConnection Open: " + ex.Message);

            }

            this.featureService = (MgFeatureService)siteConnection.CreateService(MgServiceType.FeatureService);

            this.resourceService = (MgResourceService)siteConnection.CreateService(MgServiceType.ResourceService);

 

            this.mapName = this.strMapDefinition;

 

            // if mapName is empty, I just want to work with session repository, no map session operations

            if (!string.IsNullOrEmpty(this.mapName))

            {

                this.map = new MgMap(this.siteConnection);

                try

                {

                    this.map.Open(this.resourceService, this.mapName);

                }

                catch (Exception ex)

                {

                    throw new Exception("Error UtilMap Map Open: " + ex.Message);

                }

            }

 

        }

        catch (Exception ex)

        {

            // Cleans internal references, if implemented correctly

            if (this.siteConnection != null){this.siteConnection.Dispose(); this.siteConnection = null;}

            if (this.userInfo != null){this.userInfo.Dispose(); this.userInfo = null;}

            if (this.featureService != null){this.featureService.Dispose(); this.featureService = null;}

            if (this.resourceService != null){this.resourceService.Dispose(); this.resourceService = null;}

            if (this.map != null){this.map.Dispose(); this.map = null;}

 

            throw new Exception("Error UtilMap criation: pstrSessionMap = " + pstrSessionMap + ", pstrMapDefinition = " + pstrMapDefinition + " :: Mensagem : "+ ex.Message);

        }

    }

    

    public void SetFusionViewerInitialView(string webLayoutDefinition, double dblX, double dblY, double dblScale)

                {

                    MgResourceIdentifier resourceID = null;

                    MgByteReader reader = null;

                    string strXml = string.Empty;

                    try

                    {

                                // IT DOES NOT WORK

                        resourceID = this.map.GetMapDefinition();

                        reader = this.resourceService.GetResourceContent(resourceID);

                        //resourceID = new MgResourceIdentifier("Session:" + this.strSessionMap + "//" + this.mapName + "." + MgResourceType.MapDefinition);

                                resourceID = new MgResourceIdentifier("Session:" + this.strSessionMap + "//" + this.mapName + this.strTempLayerSufix + "." + MgResourceType.MapDefinition);

                               reader = this.resourceService.GetResourceContent(resourceID);

                               strXml = reader.ToString();

                    }

                    catch (Exception ex)

                    {

                        throw new Exception(System.Reflection.MethodInfo.GetCurrentMethod().Name + "::" + ex.Message);

                    }

                    finally

                    {

                        if (resourceID != null) { resourceID.Dispose(); resourceID = null; }

If you have the Session and MapName you should be able to modify the map without needing the MgResourceIdenifier.

Hi,

 

Is it possible to read and modify the map definition and web layout flexible definition of a session ?

 

I tried serveral combinations of map names for the resource ID, with no success.

Example:: resourceID = new MgResourceIdentifier("Session:" + sessionId + "//" + "Mapa GIS - Fusion" + "." + MgResourceType.MapDefinition);
