Does there exist a class similar to a hashtable which provides a key-value
pair collection. The key and the value has to be a string?

Hello,
I am building custom hashtable class, and thinking about value retrieval
issues. The thing is, that sometimes the hashtable value may contain value
null. If someone is reading this value like this
value = myHashtable;
then, is the value of "myKey" key is null, then the result is the same, as

How do you reset a value for an existing key in a hashtable? I need to
create a collection and compare the values with another collection: when
certain parameters are met then I need to reset the value of certain
elelments in the first collection.
I would have thought that the Hashtable.Item property would do the
trick, as MSDN defines it as "Gets or sets the value associated with the
specified key". But the actual documentation is so...

I have the need to translate values back and forth. I have created a
Hashtable to do this because I don't care about intrinsic order and I
want it to be a fast as possible. My only concern is that I doubled
the size of my Hashtable to accommodate translating both ways. Kind of
like the following, but longer with more complicated data.
Hashtable ht = new Hashtable();
ht.Add("x1", "y1");
ht.Add("x2", "y2");
ht.Add("y1", "x1");

How do I deal with this? I am getting an error for each get in the
Game class (see code below).
In the simplified example below I have reduced this to just 3 fields,
one which can be NULL. I have added 3 records to the table and ran the
program but it fails with the error above.
The application is supposed to create the hashtable of records as a
static feature which will be permanently available to my application.

I have a hash table like:
Hashtable myHT = new Hashtable();
myHT.Add("First", "Hello");
myHT.Add("Second", "World");
myHT.Add("Third", "!");
We can use key to find value like:
myHT -> "Hello"
But how can use use value to find key?

Hi all, is there a key value collection in .Net that maintains the
ordering in which I add items.
I'm finding that I'm creating a number of classes that contain a name
and then some object. I would prefer just to use some collection that
maintains the ordering in which I add things (like ArrayList), but that
maps a key to a value.
I thought NameValueCollection was the right one - but it doesn't
guarantee ordering.

Hello,
I populate a hashtable with recordID's in a "For i=0 to n" loop. Some
recordID's are duplicate but for different rows (recordID is not a key field
in this scenario). I use the value of "i" in the For loop as the key in the
hashtable (which is actually the currencyManager counter).
Originally, I was using the recordID as the key and "i" as the value. So if
I user needed to go to recordID = 12345, I just retrieve 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,...
