kernel32.dll

Highlighted
Hi all,

I'm trying to use the Call Library Function VI to call GetKeyboardState
from kernel32.dll as suggested below. I put the VI on my diagram and
right click to configure. Then I pick the dll from the
c:\windows\system directory. It gives me a list of functions in the dll
to choose from but GetKeyboardState is not one of them. I'm using
Windows95 and the version of kernel32.dll is version: 4.03.1212. Do I
have an old version of the dll?

Has anyone had success using this function call from this dll? Also, if
this is a result of an older version of the dll, is it possible to just
copy the dll from a Windows98 box? Will that screw other things up?


Thanks,
stephen

According to the MS Site, getkeyboardstate is in user32.dll, not
kernel32.dll. I'm not in a postition to check who's right, at the
moment...

I'm terribly sorry, it is User32.dll. I'll mail you (Stephan) our
implementation to make it up...

Could you post the URL to the place on the MS Site? I have not been able to
find it.
