I cannot find such functions in my install of CVI: are you using some additional toll like NI-Vision or IMAQ or something else that install this instrument?
If so, I cannot help you since I'm not using Vision in my activity: let's see if somebody else can answer your question.
In the meanwhile, you should list the software and tools you are using, including the version installed of each of them, so that the correct answer can be given.
