I'd like to know if there is a specific maner to refer a file by his path in the RT OS. i know that in windows i should write C:\... i tried to use this model in TR but the system couldn't find the file. Does someone know why?
You should be able to use the same file path description on an RT system. What kind is it anyway? On my desktop ETS, I can just use a format such as c:\ni-rt\.... and so on. Have you tried opening an FTP session to make sure that the file truely exists on the RT system? Is that how you're transferring it over? I'm assuming that in your VI you're trying to locate a file that is located on the RT system itself.
through ftp i can locate the file on the RT target (CVS) and i gave the same path to the read from spreadsheet file input. but still that windows tells me that labview can't locate the file. i wonder if really this function is supported by a RT target like CVS.
You could also use "File/Directory Info.vi" located under Programming >> File I/O >> Advanced File Functions. The function will return a list of all the files located in a specified directory. You can use that information to see if LabVIEW is able to recognize the file. Also, feel free to post the part of your code that pertains to File I/O.
Here is the vi that i made. it's very simple as you can see, but the problem is this function read from spreadsheet what seems to me not functioning in real-time.
I ran the VI and got an error because the file was not found. Since you are sure that the file is there, do you get an error when you run the VI? If so, what is the error code?. I have attached the same VI saved for 8.0.
Haven't installed 8.2 yet... Can try to help if you save it down to 8...
