programmatically create file

[olivier66]

Hi,
I can't find the function allowing me to programatically create a file in a folder what I'd like to do is to use DirSelectPopup function to allow user to select a directory and then prograammatically create a text file which name is the actual date and time.
Also I'd like the first line of the file to contain headers with the names of my measurement values.

Thanks
Olivier

Well, I'd usually start with either fopen() (ANSI) or OpenFile() (CVI) and work from there.

Sorry, super old thread, but OpenFile doesn't appear to create the file if it doesn't already exist.  Am I missing somthing?

[ElectroLund]

Yep, I was missing something.  I originally attempted this:

handleLogFile = OpenFile(logfilename,VAL_READ_ONLY,VAL_APPEND,VAL_ASCII);

 But the VAL_READ_ONLY won't create the file if OpenFile fails.  Instead, a VAL_READ_WRITE must be used.
