A while ago I posted a question about how to get operator behave
differently for reading and writing. I basically wanted to make a
vector that can be queried about whether it is modified recently or
not. My first idea, using the const and non-const versions of
operator, was clearly not correct, as was pointed out. Julián Albo
suggested I could use proxies to do that. I've done some googling for
proxies (also in this group) and personally,...

Is this the correct way to test for a method before I use it?
createRange() is, I believe, an IE only method.
function wrapSelectionInTag(selection, tag) {
if (document.selection.createRange) {
var range = document.selection.createRange();
if (range.parentElement() == element) range.text = '<' + tag +
'>' + range.text + '<\/' + tag + '>';
}

Mr Leigh Purvis gave me a very clever piece of SQL to accomplish what
is probably an uncommon objective. In it, he uses the EXISTS operator.
I can find no documentation on it in A97 HELP. I would like to read
more about this useful SQL operator. Suggestions?
SELECT CustID, OutType, EXISTS (SELECT CustID FROM tblCorrespondence
AS tblC
WHERE tblC.CustID = tblCorrespondence.CustID AND tblC.OutType = "01")

I have an operator== overload that compares two items and returns a new
class as the result of the comparison (instead of the normal bool)
I then get an ambiguous operater compile error when I attempt to check to
see if the object is null:
"The call is ambiguous between the following methods or properties:
'TestObject.operator ==(TestObject, string)' and 'TestObject.operator
==(TestObject, TestObject)"
Does anyone have any idea how to...

Hi,
I use python quite a bit to couple different programs together.
Doing so has been a _lot_ easier since subprocess came around, but
would really like to be able to use the succinct shell syntax; >, <, |
That really shouldn't be too hard to wrap in a class, but so far I
didn't succeed to do so this well, since I'm facing some trouble with
operator precedence that I do not know how to overcome.

I want to create a column alias to represent the comparison of two
columns (ie a boolean result of True or False). A simple example is:
Select VehicleFinanceID, SalePrice > PurchasePrice As isProfit
>From VehicleFinance
but I get an error 'Incorrect syntax near >'
Books online states that the select_list can contain column_name or
expression

Hi!
Is it possible to use parameter markers like this:
1.) SELECT * FROM TABLE1 WHERE FIELD1 LIKE '%?%'
If I now set parameter 1 to '' (empty string) I don't get any rows back,
but if I run:
2.) SELECT * FROM TABLE1 WHERE FIELD1 LIKE '%%'
I get back data I expect.

There are many languages around: C++, JAVA, PASCAL, and so on. I
tried to learn C++ and JAVA, but ended up criticizing them. Is it
because C was my first programming language?
I like C because, comparatively, it is small, efficient, and able to
handle large and complex tasks.
I could not understand why people are using and talking about other
programming languages.

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
