TTMSFNCAppLock

TTMSFNCAppLock is a non-visual component to lock the application with a password during run-time to prevent any unwanted user access.

The application can be locked programatically by calling the Lock method or if the ActiveOnIdle property is set to True, the application will automatically lock itself after the idle time is exceeded.

procedure TForm1.Button1Click(Sender: TObject);
begin
  TMSFNCAppLock1.Lock;
end;

When the application is locked it can be unlocked programatically or by the user through a dialog.
