Thank you for fixing string formatting. However, I still do not understand why it is not an article. I have looked at your description of article versus tip: http://www.codeproject.com/Articles/64119/Code-Project-Article-FAQ#requirements http://www.codeproject.com/Articles/64119/Code-Project-Article-FAQ#whatsatip If I am not missing anything it is an article – a few pages long, referring to others people work, provides a code, a justification of solutions, and detailed documentation, and download.
