In the latter snippet, it's not that the string is const - it's that the variable is const .
Yes, those are exactly the same.
The constructor of the SqlCommand will not "see" any difference, and will therefore act the same way .

For Interlocked.Increment that probably it will not be treated ....
Is that the target method has no idea the field is marked as volatile , and therefore will not treat, the calling code doesn't know to treat it in a volatile manner.

If ((isset($var) && $var === "0") || !empty($var)) { }
This way you will enter the if-construct if the variable is set AND is "0", OR the variable is set AND not = null ("0",null,false)
This should do what you want:
function notempty($var) { return (... .

Use 'json' as 4th parameter of function $.get
$.get(url, params, callback, 'json'); .
Methinks you mean $.getJSON rather than $.get.
Call jQuery.getJSON() instead of the more generic jQuery.get().
