[mapguide-users] Check if resource exists in repository

[Tony Tang]

Try using 
MgResourceService::EnumerateResources(MgResourceIdentifier * resource, INT32   
           depth, CREFSTRING type)  on the Library resources.
It will return a MgByteReader object if the resource exists or 
           an exception if it doesn't.

You can test it with the http://<machine>/mapguide/mapagent/index.html page.

Hi Adria`,

There is currently no such API.

You can use the GetResourceContent API which returns the resource or throws an exception if the resource does not exist.

Subject: [mapguide-users] Check if resource exists in repository

Hi everybody,
hope anyone can help me with this,

Is there a way to check if a resource already exists in the repository 
(Session or Library) i.e.
Session:$sessionId/POIs.FeatureSource
or
Library://Barcelona/Data/POIs.FeatureSource

something like:

$rsId = new MgResourceIdentifier(Session:$sessionId/POIs.FeatureSource);

if (! lostFunctionToCheckIfResourceExists($rsId)) {
  createResource();
}

Thanks in advance!
