[DYUTI]

hi....

  thank u very much mark..
 But i've still doubts in this .shall i use
"
$geometryFactory = new MgGeometryFactory();
$mgPolygon = $geometryFactory->Create mgPolygon($gp.x,$gp.y);  "

to create mg polygons from the N/E coordinates.

Instead of "geom" u have used in vb coding shall i use this $mgPolygon.Then
for getting  LayerResourceID & Schema shall i use coding or can i directly
give that values..


Thanks and regards

dyuti
