I have a class derived from a SortedList called SystemList that contains a
list of objects indexed with a string value.
The definition of the objects contained in the SortedList have a boolean
field and an event that is fired if the boolean field value changes.
The derived SortedList class has an override for the Add method. The Add
method adds an event handler for the object's event for each new item added
to the list. In the...

Hi,
Can someone point me to some good best practices kind of documentation on
use of events compared to method overriding.
Ex. In Windows Forms when should i have an event handler for Paint, and when
should i override OnPaint?
I have to implement added functionality in a child class, and am in two
minds .. to have the parent fire an event, or make the method virtual and
override in the child. Am hoping some reading with description of...

OnXXXX given the sender. It loops through the sender events and tries to get
methods from the receiver that match the pattern. For each one...

Hello!
Is it possible to find how many event handlers an event has at runtime? How
about finding whether or not an event has event handlers? In C# you can
compare the event with null to check if it has event handlers, but I can't
find the equivalent in VB.
Thanks
Amit

Hello
It seems that I should implement ICloneable to implement my own clone
object. the critical point for me is to make a control object based on
another control object that all of its event handlers are set like the old
one. Is there a way to do this job?
For example, is there a way to use EventInfo object to get all event
handlers of the old control in runtime and set my new cloned control events
to the event handlers of the old...

Hello!
I know it's possible to have several event handler for a single event but I
can't
see any point using several event handler for this.
I'm probably wrong so can anybody tell me what advantage it might give using
several
event handler for a single event.

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:

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,...
