hi all
I am trying to open some .raw files that represent images (256x256, 8
bit per pixel, no header) in a c++ program
I cannot copy paste the module here as it uses a method from the VTK
(Visualization Toolkit)
the module i ve got is already tested with the same dataset and it works
if these files have been created under windows and copied in linux (i am

Hi all,
I suppose some of you know the program Redmon (type redmon in google, first
result). This neat little tool allows to hook up any functionality to a
printer by putting the file printed to the printer to standard in.
You have to provide yourself the program that does something with that data,
so I thought with some quick c/c++ programming that would be no problem. I
tried dozens of ways of reading the data from stdin or cin,...

So I am converting some matlab code to C++. I am stuck at one part of
the code. The matlab code uses fread() to read in to a vector a file.
It's a binary file. The vector is made up of floats, which in matlab
is 32 bits. How do I get this binary file in to floats in c++?
I try reading the file using the ifstream>>myFloat. But nothing ever
goes in to the float. So the closest I have come is having 4 unsigned
char store the binary data....

Cheerio,
I would appreciate opinions on the following:
Given the task to read a _complete_ text file into a string:
What is the "best" way to do it?
Handling the buffer is not the problem -- the character
input is a different matter, at least if I want to remain within
the bounds of the standard library.

I am working on a code library which needs to read in the data from
large binary files. The files hold int, double and string data. This
is the code for reading in the strings:
protected internal override string ReadString()
{
stringLength = fileStream.ReadByte();
moInput.Read(byteArrayBuffer, 0, stringLength);
return asciiEncoding.GetString(byteArrayBuffer, 0, stringLength );
}

I'm trying to read some binary data from a file created by another
program. I know the binary file format but can't change or control the
format. The binary data is organised such that it should populate a
series of structures of specified variable composition.
I have the structures created OK, but actually reading the files is
giving me an error. Can I ask a simple question to start with:

Hi. I'm having trouble reading some unicode files. Basically, I have to
parse certain files. Some of those files are being input in Japanese,
Chinese etc. The easiest way, I figured, to distinguish between plain
ASCII files I receive and the Unicode ones would be to check if the
first two bytes read 0xFFFE.
But nothing I do seems to be able to do that.
I tried reading it in binary mode and reading two characters in:

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:

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,...
