Hello,
I've got trouble reading a text file (event viewer dump) by using the

After 200 - 300 lines that are read correctly, it suddenly stops
reading the rest of the file...
Thank you to all of you who can help me with this one...

This may be the wrong group but I didn't see anything for VC++ so I'm
trying here.
I have a C++ book by Deitel and Deitel that says I can use fstream
File("data.dat", ios::in | ios::out | ios::binary) to declare a file
object with read/write modes turned on for working with binary data.
I've tried this and my file is not created. The only time it is created
is when I specify ifstream or ofstream but not fstream. I've tried

Hi!
I'm having trouble reading text lines from a file describing the levels
for a simple game I'm creating.
Inside the function that reads the content of the file there is a loop
that basically looks like this
ifstream file("levels\\level1.txt");
string line;
getline(file, line);

Hi All,
I am facing some problem using istream_iterator for reading the
contents of a file and copying it in a vector of strings.However the
same thing works for a vector of integers.
The code that doesn't work is
std::vector<std::stringvecStr;
std::ifstream fstrRead("Test.txt");

I tried your advice, and replaced "ifstream" with "std::ifstream". I also
replaced instances of "ofstream" with "std::ofstream". Those syntax errors
were resolved.
When I added "std" to the following statement: m_InFile.open(m_sFileName,
ios::in | ios::binary);
which became
m_InFile.open(m_sFileName, std::ios::in | std::ios::binary);
I get the following errors:

Hi,
I'm writing a program which creates an index of text files. For each
file it
processes, the program records the start and end positions (as
returned by
tellg()) of sections of interest, and then some time later uses these
positions
to read the interesting sections from the file.

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...
