This message is in reply to a prev 1 .
My application refues to close . Some one had suggested that I might
have threads running.. but i solved that problem too . The app still
refuses to close . !!
Here is the code for one of them !!
I call a stop function to disconnect all objects (close ) . I also
make a call to Stop in the Dispose() function .
PLs Help
