In Access 2000, Win NT, Citrix, we have each user opening the front end mdb
in their own folder, and linnking to the back end. I've noticed that a user
can get more than one instance open at a time if they are not careful.
Is there a way to have an instance of Access check to see whether there is
another one already open for this user, and if so, simply to maximize the
window of the already running instance?
Thanks

Hello,
Is it possible to find out if the current code if executing in the full
version of Access or if it is using a runtime? We have a number of
roaming users running a mixture of versions, but using the same
program. I need to implement features such as spell-checks, but don't
want to confuse the runtime users with options they cannot use. Is
there some sort of check that can determine this?
Thanks

Hello, I was wondering if there was a way to check there was already a
form open before opening a new one, sorry that doesnt seem clear, here
is an example:
The following button opens a new form
private void btnAbout_Click(object sender, EventArgs e)
{
avernusAbout About = new avernusAbout();
About.StartPosition = FormStartPosition.Manual;

Hello,
following problem: At program end or release an assembly a serial device
should get a final exit sequence. How can I do this?
With Dispose() it's no problem, but this assembly is used in a com
interop dll and it must be guaranteed, that the final sequence is send
to the serial device, when the calling application dont send Close() or
Dispose().

I found a stored procedure online a while back and want to inplement it. The only problem is that it doesn't check to see if the number generated is currently in use in the DB.
I know it's really unlikely for the same number to be generated twice (with a 10 digit number) but it's for a shopping cart so I need it to be 100% reliable.
I thought about opening a cursor then looping through each distinct record in the DB but couldn't figure...

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....

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...
