Hi,
Does anybody know where this term comes from?
"First-class object" means "something passable as an argument in a
function call", but I fail to see the connection with "object class"
or with "first-class airplane ticket". I just find the name a bit
strange. Also, if there are first-class objects, what would the
second-class objects or economy/tourist class objects be? :)

Hi,
I read a tutorial on function pointers in a swedish computer magazine.
The author used functions named dlopen() and dlsym()
(found in "dlfcn.h" under linux) that gave him the ability to get
function pointers from strings, ie :
typedef int (*fp) (int, int);
(...)
void *handle = dlopen (argv, RTLD_LAZY);

Is there any way to find a string representing an object's class,
which will work in Internet Explorer 6?
"typeof" doesn't work -- it returns "object" for all objects:
x = window.open('http://www.yahoo.com/');
alert(typeof x);
And I found this page:

Hello All:
I would like to expand upon the typeof operator.
Using 'typeof' I can distinguish between string and
array for instance, because typeof returns "object" for
array.
How can I programmatically distinguish between an Array and an Option,
for instance?
Thanks

We have a data-centric application where all of the "layout" for each data
centric page is to be codified (ie. it is expressed in C# code rather than
being expressed declaratively). This codification subsequently produces the
required web-controls for a page based on whether the page is eg. in view or
update mode, examination of the user's security permissions for certain
fields, etc.
In VS2003 our "Page Master" (to use the VS2005 term)...

does it matter if I write
var anchors = document.getElementsByTagName("A");
or
var anchors = document.getElementsByTagName("a");
Or is there a better way to catch both <a hrefs and <A HREFS

I'm using a javascript "slide" function to move a <div> layer in 10 pixel increments from one location on a page to another. The layer contains a GIF image. It's basically a side panel that flies out when you click a button. The button is an invisible GIF with an anchor that calls slide() onClick.
The animation works fine in IE but in Firefox I'm getting a series of afterimages as the function moves the layer to the goal. The image is painted...

I'm sure I'm just missing something here but is there a way to nest
objects inside an object or a collection that functions like an object
with properties BESIDES creating whole classes or making public
variables?
Private Sub Click()
Dim x as SomeSortOfCollection
msg box(x.Name & " " & x.Phone)
End Sub

Hello folks,
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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
