activate/controlling the parallel port in winXP

[Guest_imported]

Hey,
Im trying to activate the parallel port under XP using some C++ mumbo-jumbo. I wanna send some 1/0 data to the port.
I.E. :
#include <iostream.h>
#include &quot;access.h&quot;
#include <conio.h>

void main()
{
ActivateParallelPort();
SetPin(1,true);
SetPin(14,true);
getch();
deActivateParallelPort();
}

Any Ideas?? I want to send an on/off signal to turn on some LED's occording to the pin #. Thnx

I found that this code works with NT but not with XP.
Anyone tell me why that is???
