LabVIEW Converting a String to a URL in LabVIEW

[Jason_D]

Overview

This VI exemplifies how to takes a string and encodes it to a URL stripping unusable characters and correctly formatting it.

Description

URL encoding requires that only alphanumerics [0-9 a-z A-Z], these special characters $-_.+!*'(), and "reserved" characters used for their normal purposes may be used uncoded within a URL.

Requirements
LabVIEW Base Development System.

Steps to Implement or Execute Code
1. Load the attached VI "Calculate Cube of a Number LV 2012 - NI Verified.vi" as a subVI.
2. Set the string that you would like to encode in the String Control
3. Select if would like to encode spaces
4. Run the VI

Note: When encoding a filename or path, set this to false (it uses %20 for spaces). When encoding arguments for a CGI POST or GI GET set it to true.

• Consider build in Escape HTTP URL.vi
• I think the characters must be convertet to HEX strings. I would add %x as format string to fis .
