passing type var in labview to Javascript

[chickenbleep]

In labview 8.2 I'm outputing two XY numbers as type VAR. I need to read these in another Javascript program I have written. I am looking for the easiest way to read these number as efficiently as possible. I know it is possible to output these numbers to a txt file in labview, but I wanted to know if there was a way to directly read the numbers into javascript. By the way, sorry for the wonderful name.

Hi CF,

In labview 8.2 I'm outputing two XY numbers as type VAR. I need to read these in another Javascript program I have written.

I've passed data from LabVIEW to Java via a tcp/ip connection - that would be a  bit better than the temporary text-file!  Not sure about passing the VAR type, though.  If VARiants have some universal representation, then maybe it can be unpacked on the Java side, otherwise, I'd consider serializing/passing simple numeric types.

Cheers!

Hi,

Check out this thread. Calling a VI as an ActiveX Object is an option for you. Try this command:

response = vi.GetControlvalue("Output")

Happy coding!
