Hello,
I am having a problem in which a file can get stuck open when a thread
that is attempting to write to it gets aborted (ThreadAbortedException
occurs). The log file gets stuck open until the process is shut down
(cannot delete file from Windows Explorer, for example). My test
application stops execution with:
An unhandled exception of type 'System.IO.IOException' occurred in
mscorlib.dll

Hello,
I am writing an application that needs to read a file that is already open by another process for writing.
When I do the following:
FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
I get the following exception:

Everything I have read suggests that if I open files or database connections
or the like, that I should explicitly close those said resources before
making the object subject to GC. This is obviously good programming
technique.
However what happens if this practice is not followed. e.g.
that I have a base object that creates an instance of a filestream and for
arguements sake an instance of a oledb connection.
Both sub objects are...

Greetings,
I have a "newbie" question in relation to opening files from C#. I have
a Windows form where I allow the user to type in a file extension in a
text box (e.g., "xls"). I then take that extension and use that as my
filter criteria for the File Open dialog.
Once the user selects a file with that extension (from the File Open
dialog), I simply want to open that file (whether it is an .xls file,
.txt file, etc.). I am...

Hi All,
I am working on the situation where 2 different
Process/Application(.net) tries to open file at the same time....Or one
process is updating the file and another process tries to access it,
it throws an exception.
How to solave this problem? So second process can wait until first
process completes its processing on the file.
Thanks in advance

I have a .CSV file (comma delimited) that I want to open using OLEDB, but I
get the error "External table is not in the expected format."
If I save the .CSV file to an .XLS file, I can open the connection with no
problem.
What is the correct way to open a .CSV file ?
If I can not open the CSV file, how can I programmatically save the CSV file
to an XLS file ?
Thanks a lot.

There are 10 files in the folder. I wish to process all the files one
by one. But if the files are open or some processing is going on them
then I do not want to disturb that process. In that case I would
ignore processing that particular file and move to next file.
How can I check whether the file is open or not?
I tried os.stat and os.access but I am not getting the expected
results.
Also I checked in IO exceptions, IO error handler...

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,...

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...
