Vista and Monitor Power Saving

How can i prevent vista to go in to powersave mode (turn the monitor off) when i play my blitz3d game with a joystick? There is no problem
if i play the game with the keyboard.

Shouldn't joystick activity prevent "power saving" or wake up the pc/monitor from sleep,like a keyhit or mouse activity/mouse button hit does?

Maybe you could use an API call to fake a keypress every thirty seconds when the game is active ?

Good idea, if i only knew how to do that ;)

I'm not sure if this will work under Vista.
First of all, create a file that is called "user32.decls", and place it in
c:\program files\blitz3d\userlibs
Put these lines in that file:

.lib "user32.dll" 
api_keybd_event%(bVk%, bScan%, dwFlags%, dwExtraInfo%) : "keybd_event"

After that you can use the command api_keybd_event() in your programs.
This code will press the key "A". Note that you should not only press the key, but also release it afterwards.

Repeat

api_keybd_event($41, 0, 0, 0) ;keydown
api_keybd_event($41, 0, 2, 0) ;keyup

Delay 2500

Until KeyHit(1)

End

First open notepad, then start the code, then switch to notepad.
Every 2.5 seconds, it will press the 'A' key.

Wait, I found something else that might work better:

I will try that, thanks a lot for your help.

I use the API call to fake a keypress, and it works great!
Thanks again Warner.
