Yes. Create a file of sufficient size, then read and write selected locations by first setting the file position. Use all low level file IO.

hi altenbach,

                        Do you have any vi regarding this 

[altenbach]

No, but this seems trivial to do from scratch. What have you tried?

Here's something to get you started.

hi crossrulz,

                      I tried to create its not working for me. Is it possible to get VI file

[crossrulz]

If you are using LabVIEW 2014, you can just save the image I left you and then drag it onto your block diagram.  It is what is called a "snippet".

Alternatively, you can post what you have tried and we can tell you where you went wrong.

Hi, 

        I have attched my vi code

[crossrulz]

1) You need to set the file position

2) You should set the data type on the read to be a U8 to get that byte.

3) You told the read to read nothing.

4) You will need to put something in your file in order to read it.

Try this:

Currently it read everything. It would be easy to change it so it reads only one byte.
