How should a write a class to a file?
Would this example work:
object *myobject = 0;
tfile.write(reinterpret_cast<char *>(myobject), sizeof(*object));

Hi all,
I have a process, where I take a dataset from an SQL call, and need to write
an XML file from that dataset.
The data set can contain 10's of tables, each with 100's of rows, and I have
no way of knowing what the tables are, or what they contain.
I am currently using the Dataset.WriteXML method passing an XMLWriter.

hey every1,
I've got alot of data to write out to file and it's all just 1's and
0's.
It's all stored in 2 dimensional arrays of width 32 and varying
height.
At the moment it's all just integer arrays and the individual 1's and
0's are being written out as integers.

I am just starting to use python, and as such my question may well be a
bit simplistic. I am currently trying to write what should be a very
basic set of routines for reading and writing to a binary grid format
(ERMapper). However:
I am struggling to find the correct tools to write a row of a
2-dimensional array to a binary file. In matlab the command looks
like:
fid=fopen(filename,'wb');

Hi,
I have an array of data (which I am getting from a socket connection).
I am working on a program which acts on this data but the program is
written to work on data from a file (not from an array). I cannot
change anything in the program but can add some features by which I
can convert this array of data into a file. The easiest thing would be
to write the data into a file (in hard disk) and use it. But I will be
working on thousands...

Hi!
In my code, I have an array of a structure, which I want to save to a
binary file. When the array is just created, everything works fine, but
when I change contents of the array, saving results in a file, which
doesn't hold the information of the changed array anymore. I dont know why.
Here is the code:

Hi,
I have a 57000 bit long binary number and I want to save it to a file.
At the moment I am using an unsigned char array to store the array and
then fwrite to store it as follows.
fwrite( BinArr, sizeof(unsigned char), 57000, BinFile);
But it is a waste of space as this takes up around 57 KB which if I

Hello,
I'm trying to write an array of structures named myStructArray to a binary
file and later on read it back. Although I could complete the entire project
in C in about 2 minutes, I obviously have my head up and locked when it comes
to C#.
My first attempt to read such a file was something like:
myBinaryReader.ReadBytes(sizeof(myStructArray));

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...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
