Hi MaxiMuz,

in LabVIEW a string is defined by it's length, there is no special "end of string" char similar to a zero byte in other programming environments!

The "end of line" char usually CR…

How I can to define end of multi-line string ?

To define the length you could use StringStubset and provide the desired length!

You can use the Spreadsheet String to Array with a newline constant as the delimiter to convert your string to an array and then get the array size to determine how many lines are in your string.  Not sure if that is what you are asking.

That to define the length I must to know this length. For example , I am reading txt-file  by "Read from Text File". Its is multi-line string, and I don't know how many the row it contains.

Right click the Read from Text File and select Read Lines.  This will read each line of the file into an array index.

Thanks for the advise !

But , if as delimiter to use the LF(line feed), in this case if last lines are empty, then a last line don't considered.

Properly to use CR (carriage return).
