And it seems the application build in Linux does not work in Windows either.

Thanks you ShaunR and InsaneObject! Your suggestions do help. When I check in MAX, I found the NI-DAQ is not installed . (I haven't specifically informing our PC administrator to include this when he install LabVIEW for me. It's my own fault....)

Hi fellows, Need your helps! I always use "VISA resource name" control to define the I/O port and it always work.(LabVIEW 2009) Today suddenly I found that the "VISA resource name" control pulldown list shows nothing but "Refresh" ... ... , nothing is detected. (I have a printer which is always connected so at least LPT1 should show up.) Is it because certain relevant LabVIEW system application service is stopped? What could the problem be? Many thanks. Best regards, Mars

Dear Lava fellows, I found that LabVIEW offers a poor documentation about these two vi: Fire Software-Triggered Timing Source VIand create Software-Triggered Timing Source V. Anyone has experience on using them? It will be great if you can post you vi as examples. Many thanks. Regards, Mars Su

The result will depend on what algorithm you chose for interpolation, e.g. linear interpolation, polynormial interpolation ... Wether the interpolated poionts will located on or inside the original surface, it's up to wheter the mathematic model of your surface happen to be close to the model you used for interpolation. And I think your question is a pure mathematic problem, not related to LabVIEW at all. (Just Personal idea!)
