Having trouble with those new TruClient Functions? Here's why
LoadRunner 11 has added the AJAX Truclient protocol, and with it new functions for it that are unlike the old C-based functions. As of this writing, there still isn't an entry in the function reference for the protocol with examples of usage, but only documentation found in the help documentation.
However, recently we found that some of these functions are not correct. HP recently added a new knowledge base article address this:
LoadRunner GUID Creator
If you need to create a GUID on the fly for a unique ID, here is some code to do just that. Thanks to Chris Butts for this.Here is the GUID function. Set this somewhere outside the Action() function to keep it separate.

Vugen: Trim Strings With Dynamic Lengths On Left
Sometimes you need to strip off the first part of a string because there is some character and/or amount of crap at the end that you don't need. The most obvious use of this is when you capture an e-mail address as a parameter and the string is like: Issue: While using the lr_load_dll function, the user receives the following error: The web_convert_param function either converts HTML text to plain text or URL, or converts plain text to URL.
