hi NC01, Thanks for the reply. actually the original requirement is i am doing  chat application and going to use that application in microsoft media room.i am creating browser application which has chat  logic inside that. i  am doing this application and have to call the web pages in MSTV simulator.so the simulator doesn't support toolkit.it only supports xhtml and ajax(not toolkit).so i hve to refresh the status of the chat users every 10 seconds.but i should not use ajax toolkit. thats why i hve asked help for  xmlhttp. so i think now you can understand my problem. so please help me in this

Hi,

Did you tried Page Method? It easy, but I'm not sure whether your simulator support or not.
