Close RTC Automatically

Hello Nav Experts

I would like your help in solving a situation.

In Nav 2009, I used a codeunit that monitor all the clients accounts.
If ever the account is expired, and the client open his Nav, a form appeared.
The form display a warning message and on closing the form ( or pressing the 'Esc' key), the navision close automatically.
This code is being used to close the navision.

v := '%{F4}';
CREATE(wsh);
wsh.SendKeys(v); //send Alt+F4
CLEAR(wsh);

wsh is "'Windows Script Host Object Model'.WshShell"

So now there is Nav 7.0.
What ever i have done in Nav 2009 on the classic side, cannot be done in the RTC.
Nav 7 doesnot even allow me to create wsh on the RTC. It can only be created in the classic side.


So my question is how can i close Nav 7.0 RTC automatically?
What donet or any other component can i use to help me to close the RTC automatically.

Thanks a lot for your help
Heveen
