okay.. I resolved the problem by storing data in buffer and some classes to check the data in the buffer, if data is valid it will updated on the GUI.No problem in this, its working now. I need a suggestion on my new Query.. Can we insert a image on image something like my first image is GIS MAP (screen shot of google maps after zoomin it to my location). Now there is anyway option or idea to insert a pushpin on the Image at the background. similarly like google map, inserting red pushpin for any location. How to insert pushpin image on map image(screen shot of google map).
