standalone application(.exe file) not getting closed in the task manager

[DAHIYA Nitesh]

Hi!!!
 
i have developed a stack which is calling and then running another stack
from the server.
now when i am saving this is as a standalone application, even after
closing the main stack window in the .exe file
it keeps on running in the task manager.
 
can anybody know how to solve this problem??
i mean how to close the .exe process when stack is itself closed
 
and 1 more thing if i just open the .exe file nd close it without doing
anything
then the .exe file is automatically removed from task manager..
 
regards
Nitesh
