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.

Hey there :)
I was once told that the STL classes had member functions to write their
data to disk and to restore that data. Searching google (and why are there
no "stl" or "map" manpages?), it seems like someone was pulling my leg,
because I really can't find anything about it.
So, was I misinformed? Or perhaps this person was talking about some other
classes you could use to do such a thing?

I am porting an application from C++ to C#, and am having trouble finding a way to quickly and efficiently write structures to a binary file. In C++ this is trivial because all that is necessary is to pack the structure to 1 byte boundries, and then just write out the structure directly to the File IO function
pragma pack (1
typedef struct
char var1
int var1
}MyStruc
fwrite(&myStructure,sizeof(MyStruct),1,filepointer);

Hi Sharpies,
I have a C program I am converting it into C#. Everything is fine
except this process creates a 6K byte binary file. This file initially
filled with 6K null and then start populating only the fields with
value in specified locations(3 seperate structures). The way the C does
is by creating a structures, which will be filled with null initially.
Then selectivly populating only the fields with values and only up to
the length...

Hi
I need to write the contents of a structure to a binary file - there is one
string and 2 integers, but I can't seem to figure out how to write the data
correctly.
If I am simply writing text to a file there is no problem - that starts when
I attempt to write the structure.
Can someone help me out, please?

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:
1)
handle=file('image.gif','rb')

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:

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
