Hi, 
Am doing Ph.D in National Institute of Ocean Technology. I have to write a code in labview. 
I have to generate a spectrogram and store spectrogram in the jpg file format in crio. The code works on my local PC. When I deploying the same in crio, it didn't work. It returns zero. Also I tried the paths like c:test.jpg or /c/test.jpg; both didn't work. We are using Labview 2011 full professional development system. 
cRIO 9025 
Chasis 9113 
NI 9229 
Thanks for the help. 
ASAP. 
Regards, 
Ashokan
