hi, in win9x you had the possibility to use SystemParametersInfo with 97 (Screensaver running) to disable the windows, ALT+Tab and some other keys. how to do that in win nt?
In NT that happens automatically, but it's good practice to call SystemParametersInfo anyway.
you said that that happens automatically. but how? where does win nt know from if a screensaver or a normal program is running?
If you want to know how screensavers work - Check out http://www.wischik.com/scr/howtoscr.html Is your post out of a problem or just for learning ? I have written an OpenGL screensaver in MASM32 and have had no problems with it on 9x or NT4.
