JNativeTest3 on Thinkpad T60p compiles and runs for about half a second then gives a big, fat error.

Hey, it's me again.

Additional info:
The python code "ShockSensor" 1.0 by Simon Johnston, (downloadable from IBM's website) works fine, so I'll be using that for my purposes for now.

It appears that instead of opening the dll directly like you do, they are opening the device as a file like this:
handle=win32file.CreateFile(r'//./ShockMgr', GENERIC_READ,FILE_SHARE_READ, None,OPEN_EXISTING, 0, 0)

Then they read the data with a file ioctl like this:
win32file.DeviceIoControl(handle,0x733FC, '',0x24,None)

I'm not sure what the magical numbers mean, but it seems to work, so I hope that helps you refine your program!
