    Question "CTRL+ALT+DEL" Message?

    Hi all,
    let's say I press the "CTRL+ALT+DEL" combination in the middle of program and terminate it explicitly.
    Is there sent any Message to program (like WM_QUIT_WITH_CTRLALTDEL, :-) ) before the program ends or is the program "roughly" terminated without any cleanup?
    (Or how could I handle the "CTRL+ALT+DEL" Message?)

    Thanks.

    Petike

    If you terminate it under "Applications" tab, WM_QUIT will be sent, and if it doesn't close in some time, it will prompt the user if it wants to terminate it roughly. Under the "Processes" tab, programs will always be roughly terminated.

    Ctrl-Alt-Del doesn't end a program. It just brings up a set of options that you can choose such as "Lock Computer", "Switch User", "Log off", "Change Password" & "Task Manager".
    It's Task Manager (or other programs like it) that you use to kill a program.

    No, not WM_QUIT.

    On many machines (including mine), CTRL+ALT+DEL pops up Task Manager directly. And that's exactly what the OP meant.

    My bad. It's WM_CLOSE. WM_QUIT is for application's internal use. But if you handle WM_CLOSE, make sure you call DefWindowProc after that.

    I just want to add, another way of opening the task manager is with the key combination "Ctrl+Shift+Esc".
    I hate real numbers.

    Ya, that one's guaranteed to bring it up. Ctrl+alt+del doesn't bring up Task Manager under Vista either, but ctrl+shift+esc does.

    I accidentally typed Ctrl-Alt-Esc instead of Ctrl-Shft-Esc. It didn't appear to do anything, although then I found that my IE window was completely locked up and unresponsive to anything! LOL!
    Is it just me, or does that happen for other people too?
    I'm running Vista Ultimate x64.

    I don't know. It just switched window, that's all.
    Who uses IE these days? It's at 60% market share these days. Time to switch, buddy!

    not that it matters that much but ctrl+alt+delete will get you task manager immediately in xp if you are using the welcome screen, if you change it to a login screen like it was in 2000, you will get a window with options. In Vista I get a set of options and I'm using some sort of welcome screen I think.

    Switch to what? Firefox looks like crap. Most pages are still designed for IE anyways.

    Ctrl-Alt-Esc does nothing for me (Win 2K right now).

    From what I've experienced, IE has superior script support that Firefox, Netscape, and Opera. Other than that, yeah it's junk. Version 7 and all.

    About the OT...

    There is no way for a process to detect it's termination (that would actually defeat the whole purpose of termination). Something you can do however, is make a separate process monitor the target, watching for termination.

    People who design pages for a specific browser should be burned alive. Web sites should be designed by the W3 standards and then checked for problems with different browsers. Luckily I don't see much of these sites coded by wannabe developers who don't know how web programming works.

    "Looks like crap"... ever heard of themes?

    And there is always Opera.

    I wouldn't be surprised. It has a lot of non-standard crap, including jscript.
    And I can't seriously understand how people don't like the look of FF compared to IE, since the design is pretty much identical.
