I am having a problem with using a dictionary as an attribute of a
class. This happens in python 1.5.2 and 2.2.2 which I am accessing
through pythonwin builds 150 and 148 respectively
In the sample code you see that I have class Item and class Dict
class Dict contains a dictionary called items. The items dictionary
will contain instances of Item that are keyed off of the Item name. In
__main__ I create two...

I am writing an application that uses a custom class which inherits
DictionaryBase so that I can add items with an associated key. When I try to
serialize the object though, I get the following error: The type
BuildingsCollection is not supported because it implements IDictionary. Here
is my class:
Namespace BusinessLogicLayer
<Serializable()> _
Public Class BuildingsCollection

This has been bothering me for a while. Just want to find out if it
just me or perhaps others have thought of this too: Why shouldn't the
keyset of a dictionary be represented as a set instead of a list? I
know that sets were introduced a lot later and lists/dictionaries were
used instead but I think "the only correct way" now is for the
dictionary keys and values to be sets. Presently {1:0,2:0,3:0}.keys()
will produce but it could also...

I am coding a radix sort in python and I think that Python's dictionary may
be a choice for bucket.
The only problem is that dictionary is a mapping without order. But I just
found that if the keys are numeric, the keys themselves are ordered in the
dictionary.
part of my code is like this:
radix={}
for i in range(256):

I need to create object cache in memory.
Each object id can be composed from several string, integer and decimal type
values.
ContainsKey does not find existing key in this case.
How to force ContainsKey to compare object contents and find key?
Should i use Binaryformatter to serialize CacheKey, overload CacheKey ==

I'm using a generic Dictionary object where it is described as:
Dictionary<this, thatstuff = new Dictonary<this, that>()
Where THIS is a class with several property values.
This works fine as far as adding the key/value pairs to the dictionary.
The problem is when I contruct a new THIS object:

Hi
I have a class that inherits from Generics Dictionary
The string that is used for the key is passed thru-out my pgm and sometimes
it has modifiers added to the key string that are used in the system.
The problem is now I have to strip the modifer to lookup in the Dictionary
and I have to copy this code whenever I need to lookup the key or if more
modifers are added

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

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
