Hehe, and we're back to regular expressions once again. I didn't

If you wish to refresh the desktop, use the following instead since
SendKeys can "miss":
VBS:
------------------------------ ------------
Dim oShell : Set oShell = CreateObject("WScript.shell")
oShell.Run "%windir%\System32\RUNDLL32.EX E
user32.dll,UpdatePerUserSystem Parameters",1,True

I've been trying with every sample script I can find on the Net, but the

I meant cases with just a few short or even single-letter
strings.
For a long list of longer strings the array may be preferable
(obviously in particular if the strings already happen to come
in the form of an array).

"cases like this"?
If efficiency is a concern, then a method call may be too expensive.
We don't have enough information from the OP to know what the best
solution would be in his case since we have no context. Mentioning re
is indeed something not to overlook though.

About time somebody mentioned this. Thanks.
However, if a to e was only an oversimplified example and the
actual case contains longer strings, then that would not work,
though similar other constructs would. Example:
Instead of
if (x === "a" || x === "bb" | x === "ccc") ...
one could write
if (/a|bb|ccc/.test(x)) ...

The "in" operator tests if an object has a property. The construct
{"a":1 ... } is an ojbect literal that has properties a, b, c, d, and e.
Those properties have the values after the colon. The "in" operator
doesn't care what the value of a property is; it just tests if the
property exists. Your if statement is testing if the variable x contains

Good catch, I forgot that JScript is far from parity with modern
JavaScript. Here is how to get it to work for arrays as well:
if(!Array.prototype.indexOf){
Array.prototype.indexOf = function(elt, from){
var len = this.length, from = +from || 0;
from = (from < 0) ? Math.ceil(from) + len : Math.floor(from);

It was really annoying me to write lots of "or" conditionals for the same
variable such as:
if( x=="a" || x=="b" || x=="c" || x=="d" || x=="e")
I figured there must be a version of the in() that I find in SQL. I found
