Is there anyway to check for existance of a file on different machine.
i.e. we have a data file (text file) thats stored on some other machine as
its not to be exposed in case the web server is hacked.
and we want to update data from this text file into our database.
I know file object but it works only locally.(i.e. work with files stored on
local drive)
If anyone could help me it will be great.

Hi all
I've written a program in VB.NET that allows the user to build quotes for installing shower enclosures. As part of the program, I've included a blank Access database. I've provided them with an interface where they can add their own clients to the database
When the user upgrades to a newer version of my program, I don't want the installer to overwrite the Access database file with my blank one again. How can I tell VB.NET to check...

Hi all
Im a bit of a newbie to VB.NET. Under vb6 if i used a class library DLL and
it wasnt available i could use the on error resume next to get past the code
that calls it and trap it afterwards and display a custom error messageor
move on. I was wondering if this is possible in VB.NET, it seems to just end
the program with a vb frameworkish error. Basically my code says:

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
