Hi Listers,

doing a querybypoint the zoom to the queried polygon is doing well, but 
the information is wrong. It gives the wrong result. Here's the code:

Thanks a lot


Peter


 $queryresult = @$map -> queryByPoint ($querypoint, MS_SINGLE, -1);
 
 
  if ($queryresult == MS_SUCCESS) {
 
    /* Bei einem Erfolg: Ergebnisse aus dem gewünschten Layer holen*/
    $resultlayer = $map -> getLayerByName ('objekte');

/* Uns interessiert nur das erste (i.e. nullte) Resultat */
    $theresult = $resultlayer -> getResult (0);
    $shapefile = ms_newShapefileObj ('C:\Programme\Apache 
Group\Apache\htdocs\immogis3w\code\data\objekte', -1);
    $resultshape = $shapefile -> getShape ($theresult -> shapeindex);
    $resultbounds = $resultshape -> bounds;  
    
    
   
    /* Karte auf diese Extents zoomen */
    $map -> setExtent ($resultbounds -> minx-80, $resultbounds -> 
miny-80,$resultbounds -> maxx+80, $resultbounds -> maxy+80); = CORRECT 
ZOOM!!!
    $resultlayer = $map -> getLayerByName ('objekte');
    $numresults = $resultlayer -> getNumResults ();
    $theresult = $resultlayer -> getResult (0);
    $resultclass = $resultlayer -> getClass (0);
   
    $dbasefile = dbase_open ("C:\Programme\Apache 
Group\Apache\htdocs\immogis3w\code\data\objekte.dbf", 0);
    $dbrecord = dbase_get_record_with_names ($dbasefile, $theresult -> 
shapeindex);
    $Dummy = $dbrecord['ID'];
    printf ("%f<br>", $Dummy);  = WRONG RESULT!!!
