Hi,
i write an extension module in C at the moment.
I want to define some constants (integer mainly,
but maybe also some strings).
How do i do that best within this extension module
in C? Do i supply them as RO attributes?

Hi,
We are distributing our Python application as the short main script (.py
file) and a set of modules compiled to the .pyc files. So far, we have
always treated .pyc files as portable between platforms, but recently we
have discovered an annoying problem. In a module, there is the following
code fragment:
Deg2Rad = math.pi/180.0
angleEPS = 0.5

Today I was working on a hideous old app that I created a long time
ago that does a lot of showing/hiding/resizing of fields on one of
the forms. I had used constants to store reference values for many
of the top/height/left settings. I noticed that some of the
constants were defined by using other constant values, and I was
impressed that VBA could do that. Here's an example:
Const row1Top = 1.0208 * 1440 ' top of first row

I use conditional compiler constants, set through the VBA IDE in
Tools, <projectname> Properties, that I refer to throughout my code to
control which code is used during development, and which during
production. Usually, this only wraps code used to control quitting
the whole app versus just shutting a form, but it can also control
many other things.
However, as part of the build before delivering an update, I have to
remember to...

I need to make a set of constants to be available for the whole application.
Public const is confined to the form from which constants are declared.
Is there a way to declare once and all forms can access the constant values?
Thanks

Gentlesofts,
Forgive me. I'm an abject newbie in your world, using VB 2005 with the
dot-Net wonderfulness.
So, I'm writing a wonderful class or two to interface with a solemnly
ancient database. In times recently past, I would have done this with
Borland Delphi. So, that's my perspective and I have my old Delphi
code to crib from. That seems good.

The Glk API (which I'm implementing in native Python code)
defines 120 or so constants that users must use. The constants
already have fairly long names, e.g., gestalt_Version,
evtype_Timer, keycode_PageDown.
Calls to Glk functions are thus ugly and tedious.
scriptref = glk.fileref_create_by_prompt(
glk.fileusage_Transcript | glk.fileusage_TextMode,
glk.filemode_WriteAppend, 0)

Dear All,
I am always confused in using constants in multiple files.
For global constants, I got some clues from
http://msdn.microsoft.com/en-us/library/0d45ty2d(VS.80).aspx
So in header file writing: const double PI = 3.14;
Every time using it, include the header file.

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

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...
