Inport/Outport with Windows XP

[OrbitBill]

I am trying to use inport and outport with Windows XP to communicate with the parallel port.

I have downloaded and installed AccessHW and replaced the inport.vi and outport.vi with those new versions, but they STILL don't run under XP.

Has anyone actually gotten inport and outport to run under Windows XP?

Any help would be appreciated.

Bill,
Inport and Outport VIs will not work with Win NT/2000/XP. NT/2000/XP don't allow users to access registers, so the In Port and Out Port VIs do not work on those platforms, and users have to write their own Windows drivers.

The AccessHW files we wrote should work for Win NT, 2000, and XP.

How Can I Access Hardware Registers or Implement In Port and Out Port on Windows NT/2000/ XP? How Ca...

According to the document that you referenced,

"The In Port and Out Port VIs do not work on Windows NT or Windows 2000 because they are not kernel mode routines, which are required for direct hardware access. To work around this, follow the Port and Memory Utilities for Windows link below. There you can download the AccessHW software which will install the necessary kernel mode routines. AccessHW will also install replacement In Port and Out Port VIs which use these routines."

BUT, I have not been able to get the replacement In Port and Out Port VIs to work under XP with the AccessHW software installed.

Are you saying that these new version of In Port and Out Port will not work under XP even with the AccessHW software installed, or am I doing som
ething wrong?

Has anyone gotten these to run on XP??

Any help would very much be appreciated!

The new version of In Port and Out Port VIs should also work on XP. The KnowledgeBase article just haven't been updated to include XP.
I haven't tested this my self, but I talked with some R&D engineers, and they confirmed the same AccessHW files work for WinXP.
You can test the files if you have a 2000/NT machine, just to make sure they are properly installed. If you can get them working on 2000/NT, you should be able to use them on XP, too.

Hallo Zvezdana,
where can I find this NEW version of InPort- and OutPort-VIs? The only file I found is the old AccessHW.zip from 1998, that does not work under WXP with LabView 6.02.
And what about LabView 7.0? I hoped, the direct hardware-access under W2k/WXP is possible with this new release. But it is not. Does LabView 7.0 work with the NEW version of In/Out-Port-VIs or is there another way?
