Hi,
We are implementing some wrappers in C++ according to the Adapter
Pattern. The classes and their methods in the Adaptee classes
(open-source library) have already the interface that we like, but we
want to rename them so we want to implement the Adapter classes in
such a way that we only have to rename the Adaptee classes. We prefer
to use #define's because of the better run-time performance, in stead
of implementing wrapper...

Here is the scenario:
I have an interface which defines get methods for data that will make
up a row in a table. However, the source of this data may, over time,
switch/change (The company may choose to change data providers).
Therefore i thought to myself, a type of Adapter Pattern is best here
and so i proceeded with that. here's an example of what i did (note
this implementation differs from the text book one due to the way data...

What's the best practice to use the dataadapter.update on a dataset that's
been stored in session? We create a dataset on one page, and later in site,
we want to call the dataadapter.update() to save the changes. Problem is,
the original adapter is long gone.
It seems like cloogy to recreate the exact adapter again, fill another
dataset, and then replace that dataset with the one in session in order to
update our records. That can't...

Hi.
We want to use a DataAdapter's update method to store changes to a dataset
back to the database. What's the best approach, if that dataset is being
stored in session and passed around the site, effectively disconnecting it
from its original adapter. By the time we get to use the update method, the
original DataAdapter is long gone.
Thanks,
Galen

My project currently requires that I integrate an ASP.NET application with
an ASP application. One of the issues I'm having is that I have some very
long strings being created in an ASP.NET application that need to somehow
appear in a classic ASP session. The strings are too long for cookies or
URLs and I'd like to avoid using a database or someother temporary server
storage.
So far what I've come up with is a .NET class that "spoofs" a...

Hello everybody,
I have a gridview, and the SelectCommand should change depending on a
Session value.
Not the WHERE, but the field that it retrieves. It goes like this:
SELECT NAME, COST, CATEGORY(###) AS CATEGORY FROM TABLE
Where Category can be Category1, Category2, etc, etc, etc, and I have the
little number in a Session. I tried to put in in some hidden textbox,

Enable and Disable in the Network and DialUp Connections manager is actually
setting a bit in the registry for the target adapter and then calling NDIS
to unbind or bind (depending on whether your disabling or enabling the
adapter).
In HKEY_LOCAL_MACHINE\Comm\NdisPower insert this value to disable the
adapter:
<adapterNameREG_DWORD 4 (0x00000004)

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...
