Iīm developing a software that send signals to the parallel port, but i actually discovered that windows XP blocks my attempts, how can i send the signals without being stopped? I already tried dllīs that say that with them i can access the LPT but i couldnīt, it simply showed no result, no errors no efects example of a dll: http://www.logix4u.net/inpout32.htm
OS: Windows XP Professional Service Pack 2
COMPILER: MS VC 2005

Did you try this as a normal user, or as admin. Newer operating systems can be pretty picky about letting programs access the hardware directly.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
i tried that as a normal user with admin privilegies, and i already saw that website, in linux i was able to access the LPT but not in windows.
