What button? Can you post a more detailed question in what you are trying to do? Show us that you have done the research, googled around, tried it out... – t0mm13b Jan 30 '10 at 23:38

Your best bet is to use the inpout32.dll which will enable you to read/write from/to the LPT port. The usage of direct addressing of hardware ports is restricted, the dll will enable you to get around the restriction as it executes an internal driver which is already built into the dll and therefore communicating with the driver in an indirect fashion. The dll can be downloaded from here, there is one available for x64bit platform here.
Hope this helps, Best regards, Tom.
