Hello there, we have a labview 7 program controlling 2400 Keithley source meter. It was working perfeclty okay until yesterday. Now the write visa is not doing its  job and showing error -1073807202

please help.

A couple of things that I would ask off the bat:

Have you tried restarting the computer?

Did you install or remove anything lately?

Have you rebuilt the software lately?

Did you upgrade LabVIEW?

That error code indicates that NI-VISA is messed up. I'd start with running a repair on your NI-VISA install and ask around to see if somebody has been messing with the computer. Are you running Windows? Yesterday there was a whole batch of updates released for Windows. Maybe your computer updated itself and in the process messed up VISA.

Hi Tim,

I have tried restarting the computer. Nothing installed or removed and didn't do anything with the software.

LabVIEW gives the following error description for that code:

VISA:  (Hex 0xBFFF009E) A code library required by VISA could not be located or loaded.

Note that you can find this yourself by either right clicking on the error code in the error cluster and selecting Explain Warning or by selecting Help»Explain Error... from the help menu and pasting in the error code.  As aestet said, this is probably due to something being installed or uninstalled and your VISA library getting removed.
