Prevent shutdown/sleep/hibernate when recording

[patti]

Hello, DVBViewer won't let you shut down the computer if you are using Windows XP. With WIndows 7 this has been made impossible by Microsoft I hear. So, here is a suggestion that I think would remedy the situation.

 

Would it be possible to tweak DVBViewer so that when told to shut down/sleep/hibernate it checks if there is a recording going on and if there is it will enter AV OFF state and let the recording finish and after that it would shut down. This check would be made if the user tells DVBViewer to go to shutdown/standby/hibernate by using remote or keyboard. In other words, tweak the DVBViewer COM to check for the existence of a recording in case of a shutdown. I have made this suggestion assuming that standby/hibernate/shutdown go through COM and not directly to windows system.

 

Of course this check would not work if the user presses the power button or some other program wants to shut down the computer but at least it would prevent DVBViewer user from shutting down in the middle of a recording, especially when going to sleep at night and pressing shut down on the remote

 

Would this be possible?

 

How about it users, would this be a useful addition to DVBViewer?

I think that the issues with SLEEP and DVBViewer/recording service need to be addressed first. If the user can properly use "Away Mode" then these issues that you have mentioned would not be a problem. The issue is that DVBViewer is a media streaming app and when you hit the power button for off it simply enters "Away Mode" as a media app is still running; chicken or egg here? If a system generated Away Mode event (WM_POWERBROADCAST) was captured by DVBViewer power scheduler then it could react to it (PBT_APMSUSPEND) and shutdown therefore enabling the PC to enter S3 sleep properly. Likewise with the issues with the recording servce preventing correct S3 sleep on stopping a recording (set thread event to ES_CONTINUOUS). Handling these events would improve the HTPC a whole heap.

Well, you put my thoughts into a more technical approach which I was unable to do. I agree that your solution would definitely be the best. Thumbs up for that!
