Now that I have a better grasp of the scope and capabilities of the C++
Standard Library, I understand that products such as Qt actually provide
much of the same functionality through their own libraries. I'm not sure
if that's a good thing or not. AFAIK, most of Qt is compatable with the
Standard Library. That is, QLT can interoperate with STL, and you can
convert back and forth between std::string and Qt::QString, etc.
Are there any...

Hi,
Can anybody tell me how to use the System.IO.Compression
Deflatestream Class.
I have a byte which is a compressed set of bytes that form a block.
I want to inflate the byte and return the new inflated byte.

I am trying to roll a simple compression scheme for network
communication in an app I am developing.
On the sender side, I compress each block of a set amount of bytes
individually, then send it over the NetworkStream along with the size
of the original data, the size of the compressed data, and a byte
telling the receiving end whether to expect more.
On the receiving end, these blocks are received along with that size
data and buffers...

The compression part of this code works fine for me, but the decompression
part of this code does not. The output file from that is the same as the
compressed file.
What is wrong with my code?
Thanks,
Jon

Dim src As FileStream = File.OpenRead(Fn)
Dim dst As FileStream = File.Create(Ofn)

I'm using .NET 2.0.50727 in VS 2005 Pro, ENU Service Pack 1 (KB926601). I've been experimenting with the System.IO.Compression classes GZipStream and DeflateStream, and I found it interesting to note that they'll create different-sized compressed files depending on the procedure you use to take in the source file's data. With one, almost every file I feed them for compression ends up significantly bigger. That code is below, almost verbatim...

Our Mainframe DBA insists that the IDTHTOIN parameter be set to 600
so
that all idle threads timeout after 10 minutes. This is causing a
particular packaged application that expects to hold idle threads
open
for as long as it wants problems. From an application standpoint
there is not an acceptable workaround that would allow the
application
to create connections dynamically at this point.

Trying to zip/unzip files from VB.NET 2005 with 2.0 .NET Framework ...
but the file created "SampleFile.zip" is not a readable zip file.
(Using GZipStream works correctly to produce a readable .gz file)
How do I properly create a .zip file without 3rd-party lib?
Dim sourceFile As FileStream =
File.OpenRead("c:\temp\SampleFile.chm")
Dim destFile As FileStream =

You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

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,...
