Hello,
It would be extremely helpful to see a log of what is happening "behind the scenes" with the driver. To do this, you can use a utility called NI-Spy which can be launched from Start >> Programs >> National Instruments >> NI Spy or from the Measurement & Automation Explorer (MAX) utility.
NI Spy is a Win32 application that monitors, records, and displays National Instruments API calls made by applications. Use NI Spy to quickly locate and analyze any erroneous National Instruments API calls that your application makes, and to verify that the communication with your instrument is correct.
You can turn the log to file feature on via the Spy >> Options menu in the program. Please attach this log file to this Developer Zone post
so that we may further help you.
Best Regards,
Justin Britten
