vb.NET: Detect whether program is closed because of reboot or just program crash.

I'm creating a vb.NET program that monitors two processes that are running in task manager. java.exe and inetinfo.exe.  Basically, my program tells me if either of those processes are shut down (crash) and pages me.

My question is this: Is there a way to tell if the program that I'm monitoring (java.exe or inetinfo.exe) are shut down because someone is rebooting the box vs. the programs being stopped by an administrator or crashing.

Each time these programs stop I get notification via pager and I DON'T want to get paged if the server is being rebooted for maintenance or whatever.

Thanks 1,000,000

I'd suggest a timer or counter of some sort.  

When your app finds the monitored program is not running, it could increment a counter or start a timer.  Then tie to code to page you into the time elapsed / count, etc. - basically provide enough of a delay for a reboot to occur and the program to begin running again.

Of course for this to work you'll need to make sure whenever your app finds the monitored program is running, it'll need to zero out the counter / timer.

I guess, in short what I need is something like this:

For lack of a better term I need the "onServerBeingShutdown(Rebooted)" event.

I want paged when my process inetinfo.exe drops out of taskmgr but not when it's because server is rebooted.

I was hoping to offer an alternate possibility (which may or may not work for you).

I'm not aware of any event such as what you're looking for.  I would be surprised if it existed because if it exists then I would think it would be possible for malicious code to intercept the event - that could lead to a virus that won't let you turn off your computer (at least short of yanking the plug out of the wall...).

Hi,

Is your program running on the same server as the two processes being monitored? If so, you could just delay sending the page long enough that the OS gets around to shutting down your program as well if a shutdown is happening. So say after the program notices that one of the processes is stopped, it could set a flag. If, after say 15 seconds, the program is still running, then send out the page. You might need to tweak the delay a little, and its not the most elegant of solutions, but it should work.

I think the comment made by DanRollins (WM_ENDSESSION) is actually the best solution to this problem, I just wasn't aware of it when I first commented on this question. But the WM_ENDSESSION windows message is in effect an "onServerBeingShutdown(Rebooted)" event!
