<pre>Warning: mysqli_select_db() expects parameter 1 to be mysqli, null given

    I'm confused: your error message cites mysqli_select_db() as the problem, but your code snippet shows you using mysql_select_db() (notice the "i" in the first one). Those are two different things that cannot be intermingled. (The old mysql_*() functions are dead and gone in the latest PHP versions, so you should be using the mysqli_*() functions now -- or PDO instead, which I prefer, but that's sort of a side issue.)

      (Protip: when you copy/paste from CodeProject, replace the text of the "Hide Copy Code" links with the proper [code] markers.)
