Read a character from a file

[Newbee_3]

Hi guys

I have a .txt file. In that file the data are stored like "$341ACF12341ACF12341ACF12341ACF12341" now I want to read the next 128 bytes after that "$" character ??

How to execute that??

Thanks in advance

"Read Text File". Then look at the "Search/Split String" and "String Subset" VIs in the String palette to slice and dice it.

Actually my file contains many $ character as the file gets updated so does the no of "$" character and their is no way to tell how many "$" is their only that each $ character is separated by 127 bytes. That is my main requirement 

Sorry for giving wrong information at the first place

Thanks in advance

Then use an offset to read the latest one... Use kind of FOR loop.

Can you please elaborate it?

Thanks in advance

what i mean to say that as soon as you read the data & appends on txt file

1. Convert the data into string.

2. Inside for loop read the substring with number of char as 120 & offset as i(Current itearation of FOR loop) * 120.

3. Read the 120 char or bytes & play with it..

See i haven't saw your code so i can give you only suggestion, Implementing & placement of components depends on your application.

                                                 If you are not still satisfied than let me know, i will elobrate again with one illustrative image

Here, assuming you are reading the entire file rather than line by line:

You can read the text file to read the data as a string and use $ as a delimiter in Convert spreadsheet string to array.

Or, use Read From Spreadsheet File.vi with $ as the delimiter.
