Hello,
I'm using the ms data access application blocks.
My question is about the fact that everywhere shared
methods are used.
Does this mean that when more than 1 user at the same
time executes the same function they can interfere with
one another as these functions are the same for all
instances of the class (and thus internal variables

I am creating a application that will be using plugins. I am doing this so that when I want to let this application work with another type of dbase system, I only have to write\install one plugin, not the entire app.
I have created a base interface, it looks like:

Hi there,
I would like to develop an interface that when implemented in a class
requires a number of shared properties or methods to be available. It seems
a Shared Member can not be used as interface member implementation?!
Is there a workaround to this problem?!
Best regards,

Hello, question,
I want to make a COM-compatible .NET DLL (Visual Basic). For this I need an
interface. The DLL has a class that must contain methods that can be used
without making an instance of the class first.
So I have a class that has methods that derrive from an interface, and the
same class has methods that are Shared....but methods that are derrived from
an interface are not allowed to be Shared...

I was trying to write an interface that would require the implementing
class to have a shared function, CanAdd() as boolean, which decides if
the current user can add a new instance of the particular class. This
authorization is at the class level, not the instance level, so it
should be shared, but I cannot find a way to require a class to
implement a shared method via an interface. Any suggestions?

Hi all,
I want to make data stored in-memory (not disk) available to several
processes. My concern is that poorly written C applications with
dangling pointers may(will) damage the data in this memory segment if
it is open to all, i.e. shared memory mapped into all processes memory
area.
I don't want to use TCP/IP client/server between the apps and a data
store process due to the overhead.

I have this nasty problem with Shared methods and what I think of as "global
storage" - i.e. storage declared outside of any subroutines or functions.
In the simple example below this "global" storage is ButtonHasBeenClicked.
In this simple example code in Form1 calls a routine in Module1 which then
calls code back in Form1 (subroutine WhatEver). WhatEver needs to access
ButtonHasBeenClicked but the reference to ButtonHasBeenClicked...

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:

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...
