Help on screensaver detail

Hi guys, I'm currently trying to learn how to make a screensaver. But the tutorial I'm using uses this code:

Code:

SystemParametersInfo(SPI_SETSCREENSAVERRUNNING,1,&oldval,0);

Curious about what it did, I looked up SytemParametersInfo() on MSDN, and under SPI_SETSCREENSAVERRUNNING, it said:

Used internally; applications should not use this flag.

So, naturally, I'm sort of confused Another flag that looked more promising was SETSCREENSAVEACTIVE. Would that do the same thing? Or should I just use SETSCREENSAVERRUNNING?

Well...The docs do say that it is used internally, however, if your code works with it (and it doesn't appear to have any negative effect on the running of windows) than I don't seem any harm done. Though because it is an internal flag I'm willing to bet that if you ran the same code with that line commented out it would work the same.

I'm willing to bet that if you ran the same code with that line commented out it would work the same.

Hmm, it might, but it's supposed to make it so you can't ctrl-alt-del. I also saw it suggested in another thread, so it would seem that it does have an effect.

Do you know any other flag to use that would set this one? I mean, I'm sort of uncomfortable messing with stuff I'm not supposed to be messing with (it does say internal..).

**EDIT**
Here's one thread:
Disable Alt-F4
