Hello all,
I have a question about unserializing a single array element from a
serialized array. Can this be done, or must I first unserialize the
array, and then access the element?
For example, given:
$data = serialize(array('4.50','0.00','0.00'));

Hi everyone
I'm posting again this question as my system was down at time of the first
posting...well something in the newsgroups was down.
I'd like to know how i should declare a constant as an array with two
dimension. I've tried the following but seems the syntax is somehow wrong.
Can someone help me in doing so or any clue would be fully appreciate.
Here is my bugged code:

Hi Folk
Is it possible to declare a constant array
e.g.
dim i() as string
i(1) = ...
i(2) = ...
seems to work but the following does not

My code obfuscator gave me this:
char buff;
to which gcc retorted:
"ISO C90 forbids variable-size array 'buff'"
and checking the standard, it appears that commas are indeed forbidden
from being in a constant expression.

This statement is legal C#:

but this statement is not:

The C# Programmer's Reference specifies that 'the only valid values of a constant declarator constant expressions'. A constant expression is defined as 'an expression that can be fully evaluated at compile-time ... Therefore, the only possible values for constants of reference...

Hi,
I'm trying to compare an array of unsigned chars(basically just data
without any context) with a constant, and I'm not sure how to do that.
Say my array is array and I want to compare it with the constant
0x00010203040506070809 where array == 0x00, array == 0x01, etc.
How do I do that. Obviously I can't use memcmp() with the
0x00010203040506070809 since the compiler will use that constant as an
address and give me a segfault. Other...

I'm new to C++/CLI and my main background is Java. I'm trying to
create an array of constants as a static member of a class. An
example is shown below:
public ref class TestClass {
public:
static const array<constant int>^ stuff = {1,2,3,4,5};
};
This gives me compiler error C4538 which basically says that you can't

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

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...
