I have noticed in the book of words that hasattr works by calling getattr
and raising an exception if no such attribute exists. If I need the value
in any case, am I better off using getattr within a try statement myself, or
is there some clever implementation enhancement which makes this a bad idea?
i.e. should I prefer:
if hasattr(self,"datum"):
datum=getattr("datum")
else:
datum=None

Error in msvc in building inheritance.obj to build hello.pyd
Hello,
I am trying to build the boost 1.31.0 sample extension hello.cpp.
I can not compile the file inheritance.cpp because the two
files containing some templates: adjacency_list.hpp and mem_fn.hpp can
not compile.
Does anyone have any solutions?

I am using the following code instead of a very lengthly select case
statement.
(I have a lot of lookup tables in a settings form that are selected
from a ListBox. The data adapters are given a similar name to the
table. Rather than making a long Select Case that could become
obsolete if lookup tables are added and the source table of the
ListBox is edited I came up with this code.)
This code works but of course it gives me build...

Hi,
I've written a very simple Simpleton design pattern class template. This
was supposed to illustrate a point. Although it compiles without nay
errors, I get link errors (unresolved external), during linking - before
anyone jumps to conclusions that this is OT, please check the linker
error message below, it is NOT OT.
Here are my class declarations/definitions:

When I try to find out if a trivial event has handlers, by comparing the
event to nullptr, I get compiler error C3918. So my natural question is
how does one test a trivial event for handlers ?

Hello group,
I am new to Visual C++ 8 and have a seemingly trivial problem using
namespaces. The scenario: I have two classes, TestClass1 and
TestClass2, in the namespace Test. I would like to create a reference
to TestClass2 in TestClass1; but the compiler doesn't seem to recognize
the namespace Test and any classes in it.
Here are my class definitions and declarations:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
