[mapguide-users] RE: guestion about update feature source

[Farah]

Hi Maciej,

I did try this sample in java and it did work. The following is the code:


      MgMap map = new MgMap();
      map.Open(resourceService, "Sheboygan");

      MgResourceIdentifier resId = new
MgResourceIdentifier("Library://Samples/Sheboygan/Data/RoadCenterLines
.FeatureSource"); 
        
      String filter = "ID = " + 2536 ;
        
      MgFeatureCommandCollection commands = new
MgFeatureCommandCollection();

	MgPropertyCollection properties = new MgPropertyCollection();

	String name = "nowa";
	properties.Add(new MgStringProperty("NAME",name )); 


	MgUpdateFeatures updateCommandRed = new
MgUpdateFeatures("RoadCenterLines", properties, filter);
					
	commands.Add(updateCommandRed);
	
	
	//exceute commands
	if (commands.GetCount() >=1 )
	{

	ReleaseReader(featureService.UpdateFeatures(resId, commands, false),
commands);
			
	}
	
	//Now test if name has changed:
	
	MgFeatureQueryOptions queryOptions = new MgFeatureQueryOptions(); 
	queryOptions.SetFilter(filter); 
	
	
	MgFeatureReader featureReader = featureService.SelectFeatures(resId,
"RoadCenterLines", queryOptions); 
	                
	        
	        
	while (featureReader.ReadNext()) 
	{ 
	   String newname = featureReader.GetString("NAME");
	   String id = featureReader.GetString("ID");
	   out.write("Name after changing:"  + newname);
	   out.write("ID :"  + id);
	}


However for this sample to work, I had to change the ReadOnly flag of
RoadCenterLines.FeatureSource to FALSE ( according to previous posts).
Hope this helps...


Regards
Farah
