I'm developing an application in .net compact framework 2.0 (VB.net) for pocket pc's and one of the features that I implemented is an autologout timer.
If the user is inactive for a specified amount of time (specified by the user) the login screen will come up forcing them to log back in before proceeding. This works quite well in most situations, however, if the device goes into stand by the timer seems to stop. It will start up again when the user comes out of stand by mode, but it defeats the purpose. Basically if the device has a lower standby timeout time than the specified auto logout value, the user never gets logged out.
Thus far the only solutions I've been able to come up with are:
1. I can set the standby mode timeout from the code. So that it is 1 second greater than the autologout time (and set it back to whatever it was before if class closes)
2. Try to handle the "Into standby mode" and "Out of stand by mode" events and compare the system times between those 2 events and see if it has <-- I'm not sure if it's possible to handle these events and will require more investigation.
3. Figure out a way to have the timer run and bring up the login screen regardless of stand by mode.
I would prefer number 3 but I would accept 2 as well, but I'm not sure how to handle the events. After talking to my product people, 1 is not an option.
