Disabling Windows Key and Alt-Tab

[Owlet]

Hello,

I'm really frustrated with trying to get windows to behave itself...

Here's what I want to do:

If my program is running, and the user hits the windows key, I want to prevent the start menu from popping up. I'm also interested in stopping alt-tab from working too.

Here's what I've tried:

- Capturing the WM_KEYUP, WM_KEYDOWN, WM_SYSKEYUP, and WM_SYSKEYDOWN messages. I can register that the key has been, in fact, pressed, but nothing I do seems to stop the start menu from popping up anyway.

- Getting exclusive access to they keyboard with DirectInput. Windows simply won't let me do that, and even if I could, I doubt it would work.

- Creating my window with WS_EX_TOPMOST, etc. System modal has been deprecated, so I don't want to try using that.

Any help would be very much appreciated!

Thanks,
Owlet

Hey Owlet,

I think you approching the problem wrongly, in that there are functions that you can use for this problem. Now i cant check this code casue im on XP and stopping alt+tab and start menu on xp is alot harder than it was before. But this code stops control alt and del and i think alt+tab and winkey as well, atleast when i made a security prog a few years back i used somthing like this code and it worked but try this it should work:

SystemParametersInfo(SPI_SCREENSAVERRUNNING, 1, 0, 0); //Turn Off Crtl+alt+del

SystemParametersInfo(SPI_SCREENSAVERRUNNING, 0, 0, 0); //Turn On Crtl+alt+del


That may not be the one for alt tab, but i do know that the function for turning off alt and tab will also turn off the winkey. Try that though.

Thanks
