Hi!
I have a problem with an access database. The database which I designed and
made using MS access works perfectly OK on my computer however it is not
working at all on computers for which it was done :)
When the client tries to open first form the access shows information about
error connected to the communication between Access and OLE or Active-X
control.
The problem is that I cannot go to the client's computer and test it because

Hi!
I have two .NET win apps that need to communicate on a TCP/IP network.
'App A' must ask 'app B' if it's allowed to do some task, and 'app B'
must authorize or prohibit it.
How can I do this kind of communication in a secure way (protected
from sniffing)? It would be a very simple protocol. Question, and two
possible answers 'yes' or 'no'.

Hi,
this is not really Python-specific but I need it for Python.
I'm wanting a method for interprocess communication which is OS-
independent (sockets would be the normal way to go), but which works if
multiple users use the machine at the same time so that one user has no
access to the communication of programs of another user.
Normally any user could connect to an open socket on a machine

Let's assume a web application (in this case a browser-based game)
with a custom HTTP server built on PHP, and a client also built on
PHP. The client uses the server to access and change data. Even if the
client server communication is not directly visible to the user (who
logs into the client), the fact that the server is publicly accessible
(a port sniffer would be enough to find it) means the communication
has to be secured.

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 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...
