You might consider declaring a global variable in your
module that contains
the reference of the last cell on which your code
beeped. Then, in your
sub, check to see if it's trying to beep on the same
cell. If it is the
same cell, just skip the beep. If not, beep, and then
set the variable to
the current cell on which it's beeping.

For something specific to your code, post your code.

Hello all,

I have an excel sheet that updates every 2 seconds from
an
SQL server that is fed by a PLC. I am monitoring the
speed
of a manufacturing line. I want a wave file to play if
the
line stops (cell value=0). I found the code for calling
sounds, but how do I get it to play once, after the cell
equals 0? I assume the code would be similar to play a
different sound when the line starts back up again?

Windows 2000
Excel 2000

Thanks,
Mike
