Hi,
I'm writing a library in C++ which is supposed to be used by people using C.
One function I have must return a string to users which is arbitrary length.
The user must be able to use this string as "char *" so I was wondering if
the following construct is safe:
char *Func()
{
static string str;

I'm working with lots of long strings now, it seems.
I have to import them & parse them constantly. The
A97 memo field type supports only 32768 chars.
What happens when this is processed...
Dim MyString As String
Am I getting VLS declaration or a FLS declaration?
Can I control which I get somehow?
I have done some homework, but I don't understand

Hello all,
I am having a problem where I get an error message when I call
FlushFinalBlock when decrypting my encrypted text. I am using the
Rijndael algorithm.
The error message is "Length of the data to decrypt is invalid" and
occurs on the csDecrypt.FlushFinalBlock.

What is a good one line method for doing a "length safe"
String.Substring?
The VB classes offer up the old Left function so that
string s = Microsoft.VisualBasic.Left("kelly",200)
// s will = "kelly" with no error
// but
string s2 = "kelly".Substring(0,200)
// results in
// ArgumentOutOfRangeException

I am trying to convert a vb6 project to vb.net. The conversion worked for
the most part except for the fixed length strings and fixed length string
arrays. Bascially the vb6 programmer stored all form data in a fixed length

I need to load the existing files, into a fixed length structure to
initialize the form data within the project.

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
