the following code tricks windows ,so that windows thinks a screen saver is running

UINT nPreviousState;
SystemParametersInfo (SPI SETSCREENSAVERRUNNING, TRUE,&nPreviousState, 0);// Disables

SystemParametersInfo (SPI SETSCREENSAVERRUNNING, FALSE,&nPreviousState, 0); // Enables

If you want to do this in win/nt/xp/2k you have to create a keyboard filter driver

Good Luck!

Oh sorry, there are some mistakes in the code

here is the correct code:

UINT nPreviousState;
SystemParametersInfo(SPI_SETSCREENSAVERRUNNING, TRUE,&nPreviousState, 0);// Disables

SystemParametersInfo(SPI_SETSCREENSAVERRUNNING, FALSE,&nPreviousState, 0); // Enables
