I have a char array and when I write it to a file using BinaryWriter the
position of the pointer is the size of the array + 1. For example: writing
char leaves the pointer at position 26 after starting at position 0. I
thought that char was 2 bytes, but this makes it seem as though it is just 1
when I write to a file. Why is this? I imagine the extra bit is just a null
bit (correct me if I'm wrong). I don't know if this helps but when I...

Hi,
In my app, I open a file using a FileStream then pass it to a
BinaryWriter. I then use the BinaryWriter instance to write to my file. But
a problem arose : The file never gets bigger than 1kb. The code calls the
bw.write(TheValue), but nothing is written after 1kb. I'm I missing
something?
Here's the way I create my FileStream and BinaryWriter :
Filename = System.Environment.CurrentDirectory() & "\msec.dat"

Hello all,
This is my first c# program. And I seem to have a problem. Here is the
code:
FileStream myStream = new FileStream("d:\\test.txt",
FileMode.Create, FileAccess.Write);
BinaryWriter writer = new BinaryWriter(myStream);
writer.Write("ntestestse");

Considering that the BinaryWriter/BinaryReader object closes the underlaying
stream upon being gc collected, is the following code correct, and if it is
what is the reason preventing BinaryWriter object garbage collection after
the WriteSomething method is executed?

I'm writing from a serial port into a MemoryStream via a BinaryWriter in my
protocol object.
After I've filled the memorystream, which is approx 200KB in size, I then
pass it up to my datahandler object where I plan to create a BinaryReader to
extract the data and format it ready for a database insert.
At the moment I close the binarywriter earlier than my call to the
datahandler object, and Ive just found out that closing the binarywriter...

// Example
BinaryWriter bw = new BinaryWriter(new
FileStream("c:\Test.bin",FileMode.Append));
BinaryWriter.Write writes data to the stream. However, it doesn't
automatically flush data any buffered data to the underlying device. What
determines *when* data is written to the underlying device, without calling
Flush function.
Thank you,

I'm trying to write a class which uses BinaryWriter as its base but allows
for queuing of write requests
Public Class QueuedBinaryWriter
Inherits BinaryWriter
I override all the Write methods like so:
Public Overloads Overrides Sub Write(ByVal Value As Byte)
m_Queue.Enqueue(New WriteRequest(MyBase.BaseStream.Position, Value))
End Sub
'same for all other Write variants

If I execute that :
Dim Temp as string = "This is a text"
Dim sw As StreamWriter
Dim fullFileName as string = "c:\text.txt"
sw = New StreamWriter(fullFilename)
sw.Write(temp)
sw.Close()
the resulting file 'Text.txt' has the same length than the string 'temp'.

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

Hello
I'm a network technician in training and I need your help.
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...
