Parallel Port under Win2k/XP

I have been trying for some time lots of drivers and code, to have direct access to parallel port (NOT to print). However, some of them work only if I have admin rights. How can I give any user parallel port direct access? I dont know very much about Windows driver's management depending on user rights.
Regards,

Take a look at the NTPort library ( http://www.zealsoftstudio.com/ntport/) which allows direct I/O port access...Andreas Masur at 2007-11-10 3:54:54 >

Thanks for replying Andreas. I should have said that I need a free component/driver. NTPort shows a nag screen. I tried to crack it, but it doesn't work. As I could see in this forum, you have good understanding about Windows drivers and devices management. Is it possible to have direct access to parallel port, using API or whatever?Thanks in advance,

I make it work! I downloaded PortTalk driver (from http://www.beyondlogic.org/porttalk/porttalk.htm). I still had the same problem with admin/users privileges. However, I modified the install routine, to make the service load automatically instead of on demand, by changing one flag in the CreateService() call (changed SERVICE_DEMAND_START to SERVICE_AUTO_START, on start type flag).Does anybody knows if that could bring me a later problem? I think is not very good to have a service being loaded always, although it may not be used, but at least it is working in any user account.
Well, best wishes from Argentina!
