Delete Space from End of Text

[jaysmall]

I know this is an elementry problem, but I have been unable to find any threads to answer this problem.


I have a text file of numbers in double form spearated by a space each. At the end of the document I end up with an unnecessary space which then gets read by my next VI as an additional entry of zero, so I would like to simply remove the space before passing it to the next VI. I know how to set the file position to the end of the file, but there is no single character delete function that I know of. Any idea how I can do this?

Hi,

Is the data you want to modify being read as a string into LabVIEW?  If so, you can use the "Trim Whitespace.vi" in the string functions palette.  This will remove any leading or trailing whitespace from the string.

Kind regards,

If you want to shorten a given file by one byte (or character), you can just set the EOF to "file size minus one".

The advanced file palette has a VI "set file size", that should do it.

There is a nice tool from OpenG to do this.  Could be useful in the future.
