You can set the bell sound produced by Chr(7) using the SET BELL TO command ( use any WAV file for it ).


>2) Keypress rate on different PCs is different, so interscepting Keypress event will not work.
First check if there is a big difference between computers for the typematic rates in the keypress event. If there is, this can be a little tricky to set it ( i would in that case start looking for api functions that can set the typematic rate or the keyboard ).
