Utility to change behavior of ATX power button (e.g.: launch an app)

The method to do it seems simple enough. Hook the WM_ENDSESSION and return 0 to cancel the shutdown, do whatever process you need to do, then call the ExitWindowsEx function. Using the uFlags parameter, you can set it to what type of shutdown/logoff you want.

Only issues I see right now is how to pull the original shutdown/logoff type from the original WM_ENDSESSION message, and a possible infinate loop causing the puter to hang. I'm sure there is a way to grab the shutdown/logoff info, I just need to do some more reading. As for the possible infinate loop, that might be a bit more tricky to overcome.

[brainstorming]
If you set the shutdown part at the end of the script and immediately close the app after you start the script then it shouldn't do it. With keeping the shutdown option in the app itself, this would require the app to send the shutdown command and then close.

Test will have to be made to see if that would be an issue.

Now to learn how to do standard controls in C++.

I grew up as a Basic programmer and have only recently gotten into Windows programming in C++. Most of my experience thus far is directed towards game programming though.

If you dont want to waste time with the interface, how about a simple .ini or .xml file where we can configure all the settings? This doesn't have to be fancy, but it does have to be effective!

Well, now that I am getting off of work I will see what I can do. I might just go the MFC route.

Any update on this?

by the way I am pretty sure that the application named in the other thred can be allowed to last more than 20seconds, iirc 20s is the standard windows time to properly close an application, and this time can be changed or forced to infinite. I'm sure I've seen it somewhere, needs some searching.. will do :P
that programs with autoit rocks

I guess I will have to learn how to code this myself. All in the sake of saving 3 MB of precious memory LOL!

I know I keep on resurrecting this... not a chance in the world I would be able to code this, but there are a ton of talented coders in this forum. Anyone seriously willing to program this?

Posts 16 & 17 have the relevant specs for the util...
