Hello,

I have an issue with searching landmarks using the Landmarks module.

1) What is the type of object LmOperation::Execute() returns? The documentation does not tell this.

The following is my function, I want to list all the landmarks found according to the nearest-criterion set.

def getLandmark(lat, lon):

      lat = float(lat)
      lon = float(lon)

      ld = landmarks.OpenDefaultDatabase();

      categoryManager = ld.CreateCategoryManager();

      criteria = landmarks.CreateNearestCriteria(lat, lon, 500.0, False , 1000.0)

      search = ld.CreateSearch();

      operation = search.StartLandmarkSearch(criteria, landmarks.ENoAttribute, 0, 0);

      result = operation.Execute()

      resultStr = repr(result)

      resultStr = unicode(resultStr)

      note(resultStr, 'info')

The value of resultStr is shown 'None' on note().
Anything wrong with the parameters of CreateNearestCriteria()?
What is the right way to traverse/access landmarks returned by operation.Execute()?

Even setting criterion as criteria = landmarks.CreateAreaCriteria( -90, 90, -90, 90) does not help, resultStr shows 'None'

I have 3 Landmarks on the phone inserted through Nokia Landmarks Application. All landmarks have coordinated close to (12.9, 77.6)
The 3 landmarks are obtained when I do the following

      landmarkIter = ld.LandmarkIterator(landmarks.ENoAttribute, 0);
      id = landmarkIter.Next();

      while id != landmarks.KPosLmNullItemId:

              landmark = ld.ReadLandmark(id);

              lmName = landmark.GetLandmarkName();
              landmarkList.append(lmName)
              lmName = unicode(lmName);
              note(lmName, 'info')
              id = landmarkIter.Next();
              landmark.Close();

      landmarkIter.Close();

Kindly help me.
Is there something fundamentally wrong? What is the right way to use the criteria?

Hello, I got the bug. My code was wrong.
The following is the code segment which worked for traversing the searched landmarks

       landmarkIter = search.MatchIterator()

       lid = landmarkIter.Next();
      
       landmarkList = []
       
       while lid != landmarks.KPosLmNullItemId:
               landmark = ld.ReadLandmark(lid);
               lmName = landmark.GetLandmarkName();
               landmarkList.append(lmName)
               lmName = unicode(lmName);
               note(lmName)
               lid = landmarkIter.Next();
               landmark.Close();

       landmarkIter.Close();

Thanks
