Hi,
I have these string data: str_data1, str_data2, str_data3, which capture
some value after a routine process A. Then I would like to write (append)
these 3 string values into a text file each time after routine process A,
the text file is named "mytext.dat" in following format with "#####" as
separator.
The maximum entries of them is 5. When reaching the fifth entry, it will
delete the very first entry.

Hello-
I am trying to write a snippet which will open a text file with an
integer on each line. I would like to read the last integer in the
file. I am currently using:
file = fopen("f.txt", "r+");
fseek(file, -2, SEEK_END);
fscanf(file, "%d", &c);
this works fine if the integer is only a single character. When I get
into larger numbers though (e.g. 502) it only reads in the 2. Is there

Hi,
I'm trying to open a file (any file) in binary mode and save it inside
a new text file.
After that I want to read the source from the text file and save it
back to the disk with its original form. The problem is tha the binary
source that I extract from the text file seems to be diferent from the
source I saved. Here is my code:

I try to follow Steve's paper to build a database, and store a small text
file into SQL Server database and retrieve it later. Only difference between
my table and Steve's table is that I use NTEXT datatype for the file instead
of using IMAGE datatype. I can not use SqlDataReader to read the data. I need
your help, Thanks.

Hello World,
I made a Windowsform that reads data from a CSV file.
It works fine, but when I have read the data of a record I have to re-Debug
the form to read another record.
So when I put a new seek item in the textbox after I searched for an item
and click the seek button.. it seems it is doing nothing.
And also... what code can I use to genereate a messagebox message when a
seek item is not at all in the CSV file?

Hi,
currently I am reading a huge (about 10-100 MB) text-file line by line
using
fstreams and getline. I wonder whether there is a faster way to read a
file line by line (with std::string line). Is there some way to burst
read the whole file and later "extract" each line?
Thanks in advance,
Thomas Kowalski

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,...
