i'm working on a project... i'm looking to use a parallel port relay board which i have already, but my pc does not have a parallel port.

so i'm using a usb to parallel port converter and i cannot figure out how to write to the board to switch the relays on and off.

if anyone could link me to some api that is in c++ or java i'd appreciate it.. i've been looking for this answer for a while.

i'm using vista 32 bit so it has the guards on writing directly to the ports and i'm having a problem there too
