When you want to store an integer in C++, you use an integral type, eg.
int main()
{
unsigned char amount_legs_dog = 4;
}
In writing portable C++ code, there should be only two factors that
influence which integral type you choose:

I am using a VB6 COM object with an asp.net project. I am storing the
COM object in a session variable but am having a problem accessing the
COM object from the session variable.
I am getting the error:
QueryInterface for interface object.class failed
I am able to create new instances of the object with no problems but
as soon as I cast the session variable to the object like so:
CType(Session("object"),object.class)

I have an application that needs to be able to upload documents that can
latter be accessed and opened by a hyperlink. I can do this easliy if I
store the files in a subdirectory in the application, but we will be using
multiple web servers, so the files need to be stored on a common file server.
Saving them is easy enough, but how do I point a hyperlink at a file on a
file server that is different from the web server?
Could you please...

Hi,
I'm writing a hand-written recursive decent parser for SPICE syntax
parsing. In one case I have one function that handles a bunch of
similar cases (you pass the name and the number of tokens you're
looking for). In another case I have a function that handles a
different set of tokens and so it can't use the same arguments as the
first one, and in fact takes no arguments. However, these functions
are semantically similar and are...

Hi,
all of the containers in STL stores object itself (thus copy
contsructability & assignability is needed), while NTL or boost
ptr_container stores pointer to the object in the container (either
exclusively owns, or just stores).
Now, my question is for a general guideline when to use which one?
What I understand,
1) polymorphic objects need ptr_container.
2) non copy constructable, non assignable objects need ptr_container.

I have worked with application settings in VS2005 and C# for awhile, but
usually with standard types. I have been trying to store a custom
container/class/type in an application setting and I have seen erratic
results. I am aware of one known defect where user classes do not show up in
the list of types on the Property/Settings page in the visual designer and I
am wondering if I am encountering some other peculiar issue, or if there are...

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...
