Summary: System.Net.ScatterGatherBuffers.MemoryChuck allocates inordinately
large bytes when sending large post data.
The following application consumes inordinate quantities of memory. My code
does not explicitly allocate memory in a loop nor does it explicitly allocate
large blocks of memory. Yet, the application’s memory footprint will grow as
large as 370 MB. Rarely will it run to completion; usually, it throws an out

I get an out of memory exception when attempting to excecute the
following code:
original = System.Drawing.Image.FromFile(file.FileName,true);
I ONLY get this exception when the file is in the "My Documents"
folder or subfolders. If the file lives anywhere else on the hard
drive, I have no problems.
What could be going on here?

Hello,
I had an earlier post regarding a strange exception I
(thought) I was getting in my windows form. I have since
been able to trace the problem to a picturebox control on
my form. I can reproduce the exception consistently, but
it seems to be timing dependent. Here is what happens:
I have a subform that I open, load an image from a file
into my PictureBox, take some user input, then I hide the

I have a function residing in a module that is doing some file copy and
database query operations. This function is called from a regular form under
a System.Windows.Forms.Timer control. The problem is that sometimes it gives
an error - even when it is doing the same exact operations. It may fail on
the 20th tick event or the 100th. The file and data has no changes - so, it
is doing the same operations repeatedly. I'm wondering if anyone...

Hi,
I am wondering why the .NET Framework is quite different from Win32 API when
it comes to displaying system modal message boxes.
Consider the four following types of system modal message boxes (please see
associated source code below):
1) Win32 API with context ("btnWin32WithContext_Click")
2) .NET Framework with context ("btnFrameworkWithContext_Click")
3) Win32 API withOUT context ("btnWin32WithOUTContext_Click")

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

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...
