Subject: [mapguide-users] Modify the map definition and web layout flexible
 definition of a session
Message-ID: <!&!AAAAAAAAAAAuAAAAAAAAAKOv5XA0LD5Bk8syEQqN4MEBANlTnCJhprtFudq2LHCBs8EBACQA//8AABAAAAC3zan6HNSBRaMeY3O1aFIOAQAAAAA=@nexxa.com.br>

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);

 

Regards,

 

Liglio Cavalcante

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

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

Using PHP (sorry my default code)

I can get the MapDefinition (from a simple InvokeURL widget - note the
lower-case mapname and session)

<?php
$configFilePath = "C:\Program Files\OSGeo\MapGuide\Web\www\webconfig.ini";

$session = urldecode($_REQUEST["session"]);
$mapName = urldecode($_REQUEST["mapname"]);

MgInitializeWebTier($configFilePath);


$userInfo = new MgUserInformation($session);

$siteConnection = new MgSiteConnection();
$siteConnection->Open($userInfo);

$featureService = $siteConnection->CreateService(2);

$resourceService = $siteConnection->CreateService(0);


$map = new MgMap($siteConnection);

$map->Open($mapName);

$mapDef = $map->GetMapDefinition();

echo $mapDef->ToString();

$reader = $resourceService->GetResourceContent($mapDef);

echo $reader->ToString();

?>
