I intended to save properties of an object to a Hashtable. In this case, keys and values are not fixed types and I cannot use SortedList.
I have no idea what order the .NET framework add items to Hashtable when Add(key, value) method is applied. Monitoring the position items are added, I cannot find if key is the standard or value.
I thought basically Hashtable function acts randomly, therefore the order will be changed unexpectedly.

I have an MDI form with a single child form. I have found a couple of
circumstances that appear to cause the framework to leak Int32s, MenuItems,
MenuItemCollections and sometimes TRACKMOUSEEVENTs. This happens if I
disable/enable a menuitem, add a new menuitem programatically or click on an
entry in the mdiList menu. I am disposing the main menu in the child form
as well as in the main mdi form, so that's not the issue.

Hello.
I have a Hashtable, to which I insert key and values.
When I go over the hashtable with "foreach" later on,
the items are not coming out at the order I inserted them.
A quickwatch showed that as the items are inserted, they are not arranged in
the hash at the order they were inserted by.
Is there a way to control that with a hashtable ? I can't even sort it...
Thanks

Hi Guys
How can I modify the items within a hashtable "in situ" so to speak?
At the moment, I am locating the item that I want, extracting it,
modifying the item, deleting the hashtable item, and then adding back
the modified item to hashtable.
This seems rather long winded, and surely there must be a simpler way
than that.

Is it possible to treat values and items of a DropDownList like a
HashTable?
My page records the value of the ConsultantName in a label
lblConsultant and the ID in a hidden field hidConsultantID
If I know the value of the ID: hidConsultantID, how do I lookup the
corresponding name, given that I have a DropDownList which maps
corresponding ConsultantIDs to their Names for the consultant

The usual trick to get around the "collection was modified" problem by
looping through the collection backwards by index won't work with a
Hashtable because there is no way to access by index, right? How do I loop
through a Hashtable to selectively remove items?

Hi all,
I have in the ASP.NET cache a Hashtable of items. What seems to be
happening,is that some of the actual entries in the hashtable are
being removed, perhaps under memory pressure, when what I would have
expected is that the actual hashtable be removed.
I cannot see an other reason that the items would be removed, other
than by the Cache itself.

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...

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'm a network technician in training and I need your help.
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...
