I receive error -200918 when trying to save a DAQmx task

[David_Jackson]

I have a Labview 7.0 application that creates and saves a DAQmx task (DAQmx version 8.0).  I can create a task but when I try to save the task I receive Labview Internal error -200918. Up until now this has functioned fine on multiple machines but recently received this error on a new Windows XP machine running SP3.  I am able to create a save the task using MAX (version 4.3).  Has anyone experiences this sort of error before?

Regards,

David

That code maps to what is now an external error code.  The error text reads:

"Global channel name specified is already used for a task in the Data Neighborhood.  NI-DAQmx does not support overlapping task and global channel names.  Select a different name."

I am not sure why that code is showing up as an internal error for you, but the new error text should get you going.

Thanks for the explanation Ben.  It turns out that the PC on which this error occurred had DAQmx version 8.6 installed (not version 8.0 as I first thought).  I removed DAQmx 8.6 and installed DAQmx 8.0 and no longer get this error.  None of the other PC's (with DAQmx 8.0 installed) receive this error.  I note that Labview 7.0 is not supported in DAQmx 8.6 so it may be that I just needed to be using a version that is supported by Labview 7.0?

We now have access to Labview 8.6 and in the near future we intend recompiling these applications and using them with the latest version of DAQmx.  Should I get any further problems then I'll update this message.
