Hi,
I'm programatically posting an image using multipart/form-data. It sends to the server OK, but when I try to view it in the browser, it is still in the base64 string I sent it as: /9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAUDBAQEAwUEBAQFBQUG etc....
I've been through the form I built over and over:
string PostData = "";
PostData += "-----------------------------7d41fb3081216";
PostData += "\r";
PostData += "\n";

Hi All,
Does somebody know what's the length's ratio in we convert byte to base64
string? Is it a constant ratio or it can be different from case to case? For
example if I convert a byte array of 20 bytes length can I expect that I get
the base64 string with the same length every time when I do that? And what
will be the maximum length of this string?
What's the schema is taken for this conversion? If we use UUENCODE or
something else...

I have a ton of files that are being generated from a legacy system. Each
file contains a (1) content type one one line, a (2) filename, and (3) the
encoding type (seems to always be Base64, followed by the encoded string.
A process will be to read the content type and filename, then create a new

Greetings.
I have managed to stitch together an awesome method of posting text
along with an image to a database, in a way that allows an unlimited
number of previews to ensure that text and image are perfect before
submission. This involves converting any uploaded image to a Base64
String and holding that in a hidden form field until either the post
gets submitted to the database or the image gets replaced with another one.

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...

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,...
