deleting a section of data from an ini file (config file)

[mkReddy]

Hi

I have a config file (ini file) which has huge data(2000 lines) which contains Sections and keys. I would like to delete a Section and keys

I am using an FGV (functional global variable). I would like to delete part of data programmatically from the file and write it back .

 Delete from array is one solution i know. Is there any best solution to use.

If you are using the Config File API that NI gives you, there are the Remove Section VI and Remove Key VI that sound like they do what you want.

Hi Reddy,

with the INI file functions you find a function to delete a key and a second function to delete a section.

What else do you need?

[Regulator]

The Sound and Vibration Toolkit has the Configuration File VIs Palette has the following available: Open, Read, Write, Remove, Remove Section, Close, Get Key, Get Section, Not a Config?. If you don't have this toolkit then parse the config file by using base package VIs - Open/Create/Replace, Read from Text File and check for sections and keys. You can put them in whatever container you want (Array,Queue). If you use queues you can flush one of the elements out.

Actually, you do not need the Sound and Vibration Toolkit to use those VIs.  They are available in the base version of LabVIEW under the File I/O->Configuration File palette.  The SVT just adds another link to those VIs in the palette.

Hi,

Read the key, change the string as needed, write the key...
