I would like to get everyone's thoughts on two new dictionary methods:

try:
self += qty
except KeyError:
self = qty

hi
I wish to pop/del some items out of dictionary while iterating over it.
a = { 'a':1, 'b':2 }
for k, v in a.iteritems():
if v==2:
del a
the output say RuntimeError: dictionary changed size during iteration
how can i suppress this message in an actual script and still get the
final value of the dict?

I was trying to get custom dictionary class that can store generic or
string; So I started with the example given by the visual studio 2005 c#

That seem to miss a few things including #endregion directive and the ending

Is there not a simple way like in dotnet vb?

Is there a way in python to add the items of a dictionary to the local
function scope? i.e. var_foo = dict. I don't know how many
items are in this dictionary, or what they are until runtime.
exec statements are difficult for debuggers to deal with, so as a
workaround I built my code into a function and saved it in a .py file.
The I load the .py file as a module and call the function instead. This
works great, and it has the added...

I am designing an enhanced GUI suite, and i need to know how to:
* Make a user control a "helper" control, ie, one that sits at the
bottom (like timer or process)
* Make this control modify the behavior of the painted controls
already on the form. (ie, make my control handle the painting of the
controls on the page)
* Make the TextBox contol have it's background painted by me. This
seems to be a hassle.
Any help would be deeply...

Hi folks,
I have a Dictionary which contains a string key and an object value. I
want the object value to point to a property in my class and I want it
to be by reference, so that later on I can change the value of the
property through the dictionary.
I am having difficulty making the value be by reference. Is this
possible? I've even tried unsuccessfully to use unsafe code with
pointers.

Hi all,
I'm trying to do something that should be really easy, but I can't think of an
obvious way to do it. I have a dictionary whose value is a "value type" (as
opposed to a reference type -- in this case, a Boolean):
Dim dic As New Dictionary(Of Int32, Boolean)
dic(123) = True
I want to set all of the existing entries in the dictionary to False. The

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...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
