Hi all !
This is my first day with Visual Studio and C#, and I'm trying to send "raw data" to the printer
port. I found the SendFileToPrinter example below in a knowledge base at MS site
It works, but I need to replace the filestream with a memorystream cause there's no need to write
files and then load them again just to print.
So I rewrote the procedure and the call. The problem is of course that it dosen't work. If I replace

I am working with the this object as oppose to the
StreamReader object becuase I need to access a file (to
find the contents) while an external application is
updating the file. When I was working with the
StreamReader object I got a deadlock when I tried reading
the file while my external application was writing to it.
So far I am able to create a FileStream object and open
the file in question (CrawlerBackup.txt).
But I am unable to...

The following method only works when i give the ASP.net account full
permissions on the directory.
It doesn't work when i give the directory Modify, Read &Execute, List Folder
Contents, Read, and Write permissions (all at the same time)
I'm only trying to READ the file. Why do i have to give it full
permissions?

I am having a problem saving an image with the same name it originally had. I have two similar versions of my code, one in which I close the FileStream used to open the original image before saving, the other in which I close the FileStream afterwards, although both return the same error. Here are the two versions of the code and the errors they each return (NOTE: I rebooted immediately before running each of these versions so that I knew they...

The following code which is supposed to dynamically create files with
incrementing names is throwing an exception due to the inclusion of the
DateTime.Now component of the sReportSave string:
string sReportSave = ( DateTime.Now + "Report.Dat" );
FileStream fs = new FileStream( sReportSave , FileMode.Create );
Is my approach completely wrong or is there different way to modify the
FileStream so that .NETclients used by multiple users...

It is my understanding that I can create an XmlTextReader from a variety of
sources, including a stream object. I am developing a web application that
reads some data from an Xml file. Everything works fine if I use the
XmlTextReader to open the file (i.e. pass it the file name):
Dim reader As XmlTextReader = New XmlTextReader("<file_name>")
But I get an access error if I try to open the file using a FileStream
object and then passing...

Probability of this phenomena is like 1/200.
The only code where I am dealing with file is the following:

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,...

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.

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...
