RTimer timer;
TRequestStatus timerStatus;

timer.CreateLocal();
timer.After(timerStatus,1000000000);
User::WaitForRequest(timerStatus);
timer.Close();


but it shows me a blank page (consol) I don't want to have any UI,
in commonFramework I have commented the console object and without these lines of code I don't have UI, but how can I hidden the console which is showing when I use above code?
