Ini Files

[NI_Device_user_sb]

Hi,

I'm currently working on a project in MSVC2005.
I used *.ini file functions provided by Labwindows CVI, in order to use those type of files.

I've seen on the Internet that *.ini files are limited to 64ko.

I need to know if it's right and if it's a problem for CVI INI functions?

Thanks in advance.

Although I cound not find official announcement from Microsoft, I believe it is true that INI file is limitted to 64KB.  Because this is the limitation of OS itself or "Profile String" API family , nothing can solve this no matter what language you use.

Hi,

thanks for your answer Makoto.

I'm running under Windows XP. And I'd appreciate if a NI A.Engineer could answer me because I'm working with their INI functions !
So they might know if it's correct or not !

I made a simple project to create a huge ini file: with 5000 items the file created exceeds 250K. The same file can be read without problems.
I tested also with 20000 items created: despite the time needed (more than a whole minute) the file was created and read back without errors  (approx 1Gb file).

The 64kB limit for ini files applies to Windows 95/98/Me technology (32kB in Windows 1.x/2.x/3.x , not NT/2000/XP/Vista. Even then, it only applies if you are using the Windows API calls to access the files. If you are using the NI inifile.fp interface, the limit doesn't apply (since it doesn't use those Windows API calls).

Hi,

thanks msaxon.

Very interesting stuff.


I'm using NI  source files which are used by the .fp file. So I conclude, I won't encounter problems.

Do you have any internet links where I can find this information?


Thank you very much, to all participants of this dicussion.
