How to identify Key source with LabVIEW?

[MartinM]

I wanto need to connect 6 keyboards to the same computer and chek for keyboard activation, I have been looking for a cheap solution by using fast switching hardware, but before try that I would like know if it is possible to use all of the six USB ports available in my computer and test the keyboards by searching key events from each keyboard just by software.

Thanks

MartinM,

Are you even able to recognize two keyboards in windows?

You must be able to use multiple keyboards. I know I've plugged external keyboards into my laptop before. Both work side-by-side. Now, if you can tell them apart programmatically? Your guess is as good as mine. I'm guessing LabVIEW's generic key stroke event detection won't expose that to the user. You'll probably need some function from User32.dll or something like that. Hope this helps!
