I have code like the following to test for existence of a file. I know the
file is there, but File.Exists returns FALSE. The problem appears to be
that the file is in a directory beneath "My Documents". When I move it to a
directory directly under the root, File.Exists returns TRUE. So I tried
using FileIOPermission to give me rights to read it, but still no luck. Any
suggestions? Thanks...

I'm using File.Exists to test a file on my C: drive.
My program was strongly named and had caspol -af run on it to allow it to
run from the network.
There are 3 ways I am doing this:
1) Run from my C: drive, File.Exists works properly and says
C:\Temp\test.txt exists
2) Run from my H:\ (network) drive, File.Exists says the file doesn't exist.
3) Run from Visual Studio debugger, with project configuration property

I am using the System.IO.File class to determine if a file exists on a
network share.
The File.Exists method keeps returning false, even though the file does
exist. The MSDN documentation states,
"If the caller does not have sufficient permissions to read the specified
file, no exception is thrown and the method returns false regardless of the
existence of path."

I am trying to see if a file exists in a virtual directory, and if so run a
method. I try doing File.Exists and the method runs but the file isn't there.
Is there a web version of File.Exists or some otherway to get this type of
functionality without too much heartache???
Thanks

The problem:
I am trying to use the SaveFileDialog class to get a filename, which is
subsequently opened for writing (write access, read sharing, but using
read/write sharing doesn't make the problem go away anyway). Sometimes, on

Hi All,
I noticed if file path has a white space, for example "C:\my document
\test.txt", the function File.Exists(filePath) always return false in
release mode. How could I make this function work for the file which
is located in a direcotry with a white space?
Thanks!

Newbie question:
I'm trying to determine if a file physically exists regardless of the
permissions on it
Using File.Exists() returns false if it physically exists but the
process does not have the necessary permissions.
One hack could be to check for length and that would throw a
FileNotFoundException ...but there is got to be a better way!

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

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

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...
