I have huge number of legacy code which use standard files functions.
I would like to pass a memory pointer rather than a FILE pointer.
I am trying to use FILEs in the code to refer to memory buffers.
Basically, I want to be able to use all the standard read and write
functions, but I want them to refer to memory locations, rather than
disk
files.
I do not want to touch the legacy code. Does any one know of a library

Hi,
Am I trying to hold the data of a DataGrid in a label so that when the form
is reposted the DataGrid can be repopulated. The problem I am having is that
I don't understand how to get the text into a stream in order to be able to
use DataSetOutcomes1.ReadXML(MyStream).
Thanks in advance,

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

Hello,
I have a file on disk called TEMP.ZIP and I would like to somehow get
this into a memory stream so I can eventually do this:
row = dataStream.ToArray()
However, I am not sure of the correct way to get it into a memory
stream.
Any help appreciated.

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:

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,...
