IMAQ Copy function does not always copy Calibration Information

[tlivingston]

This only seems to happen on one PC in compiled form- works fine elsewhere. I wrote a trap to check for the existance of calibration information before the copy, and again after the copy to a newly created image. If the two disagree, the program breaks. The program breaks consistantly on one of my machines, but never on other PCs. Does anyone know what conditions can cause this to happen?

Actually, its not the calibration information thats missing, its the pattern matching information.

Hello,

Thank you for contacting National Instruments.

I don't know of anything in particular that would cause the IMAQ Copy function to not copy the pattern matching information on one particular machine. For troubleshooting purposes, I recommend checking for any and all differences between the working machines and the non-working machine. For instance, check the versions of all software that may be used by the application (especially NI-IMAQ and IMAQ Vision). How do the systems differ in hardware? Are they all the same make/model of PC? Are they all using the same IMAQ board?

Any differences you uncover may help us figure out what is causing this behavior. Let me know your findings so I can continue to assist you.

Regards,

Jesse D.
