Error 7 occurred at Open File+.vi:open path

[HassanIqbal]

Hello Everyone, 

I am facing this error and unable to counter it even going through many treads people posted in the past. I am attaching my code and supported files for LabVIEW master's to suggest how to get rid of this error. I think I am giving right paths to the folders but code still gives this error. Interestingly I am getting partially right output.

Did you try to debug your VI?

There are not so many places where an "Error 7 at OpenFile" could happen!

I did that for you and found the problem: you are trying to access a non-existing file with your VI. When trying to open a non-existing file you will get error 7 ("file not found" as it says in the error description!)…

(Hint: the error only occurs with your test.tfd, which defines a Suprasil "environment".)

Hi GerdW, 

Thanks for your reply. Yea I could see the error 7 is originating in the case structure. 

I would like to know little bit more than hint. 

Regards,

Hassan

Use a probe to check the filepath used to call that OpenFile function! (That's called "debugging"…)
