Hi
I would like to use a string from an array to call a function. For
example, I have a list of functions called A.B,C,D etc and for various
situations I need to call a a different range of functions:
var myFunctions = ["A","C","G","B" ,"E"];
for (i = 0; i < myFunctions.len gth; i++) {
errorcode = myFunctions[i](); // I want to call A(); B() etc
}
Is it possible with Javascript, and if so, how?
Regards

Change this line to
var myFunctions = [A,C,G,B,E];
so that you have an array of function references instead of an array
of strings.
for (i = 0; i < myFunctions.len gth; i++) { errorcode = myFunctions[i](); // I want to call A(); B() etc }

Functions are values. You can use myFunctions to store the functions themselves,
not just their names.
var myFunctions = [A, C, G, B, E];
This assumes that function A et al have been defined.
You could go a step further and define the functions in the array literal.
var myFunctions = [function A() {
...
}, function C() {
...
}, function G() {
...
}, function B() {
...
}, function E() {
...
}]; http://www.crockford.com/

Hello there,
I have a front end database that I have recently made very many changes
to to allow off-line use. I keep copies of the databases on my hard
drive and link to them rather than the live databases on the network.
Is there a way, via code, when I get back in-house from being on the
road to click a button, and select the backends I want to link to?
I would want to delete all the current links and link to the "live"

So given an UserId (UID) how can I read the First Name and Last Name

would of great help.

Hi all,
I am having trouble converting the code below (found on

Can anyone have a look at it and let me know what I need to change. I
have tried changing the "hwnd" type into intptr's but there seem to be
other problems too, like it won't allow "lParam As Any" to be

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
