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);
strXml = reader.ToString();
// I CAN NOT FIND THE MAP OBJECT
//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 (reader != null) { reader.Dispose(); reader = 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);
