DAQ Assistance - No supported files exist

[vinu]

I am doing an experiment. I am supposed to take readings from the pressure transducers through Data Acquisition Card and plot graphs using labview 7.1. I made the code. 2 days before it was running properly, but when I logged into my computer today I find this error. It says "no supported files found", when I initialize DAQ. Can anybody help me out with this problem. I think the problem is with configuring the physical channels of DAQ. I dont know how to configure them. Can anybody through some light on it. It will be very helpfull in completing my project..

Hi vinu,

 “no support files found” sounds like a very generic error so lets try to narrow down where the problem is occurring. If your LabVIEW code has not changed it is possible something has gone wrong with your driver installation.

Can you open Measurement and Automation Explorer and successfully use the test panels for your DAQ card? This eliminates LabVIEW and your code from the equation and will just test your hardware and drivers. If you cannot do this then I would uninstall your DAQ drivers and reinstall them. If it does work then the problem is most likely in your LabVIEW VI.

I have a few questions that will let us characterize the problem some more.

1. Does anyone other than you have access to the computer? Could they have changed something?
2. What DAQ card are you using?
3. Are you using DAQmx or Traditional DAQ drivers? What version of the driver are you using?
4. Where in your code is this error occurring?
5. Can you post a screenshot of the error? Is there an error code associated with this?
6. Can you post a screen shot of your block diagram?

Let me know if you have any questions. Have a great week and take care.

Thanks,

[vinu]

Your reply was very helpful ..
Thanx once again ... because of you i was able to complete my code . Now I can start my experiment and finish my project .

So what was the answer?  Which of his questions helped you?  So there was something wrong with the code, or something had changed from 2 days earlier?

Please post so that if someone else searches the forums for the same problem, you would be able to help them.

there was a problem in my code as well as in my DAQ .
I solved it by re-designing the code and I also replaced my DAQ
