NI-DAQ virtual channel and NI-DAQmx task channel name problem

[duncan carter]

What are the maximum number of characters in a traditional NI-DAQ virtual
channel and in a NI-DAQmx task channel name. NI-DAQmx doesn't provide an
warning if the number of characters is exceeded and does not seem to limit
the number of characters entered to a legal amount; it crashes instead. Is
this a buffer overflow? I tried counting them but the number is large
enough for this method to be very time consuming and error prone. I'm
trying to customer-proof an application.

I do not know the answer to question.

I would like to encorage you to contact NI about this issue.

If this is a bug, we should let them get working on it asap.

I thought these forums were monitored and were suitable for bug reports.

Not really.

This forum is just alot of users who like to help others.

NI people participate in this forum, but I do not think they are required.

If they are required, then they are falling down on the job based on the number of un-answered Q's.

If you can re-create this problem, call NI at

800-433-3488

and explain what you did to see the issue.

My record time is 14 minutes from the time I was talking to a support engineer until they said "Corrective Action Request" (i.e. double talk for "Bug Report").

Please share what you find.

After my last post, I forwarded a copy of the post to Leonard Nava.

Justin Britten of NI reports that the limit should be 64 characters and that
the problem is under investigation.

Thanks for the update Duncan!
