Question,
When using BeginInvoke (on a From to marshal to the UI thread) with the
EventHandler delegate I see some strange behaviour. The problem is that I
call the UpdateTextBox method with a class derived from EventArgs ( i.e.
MyEventArgs) and when the BeginInvoke is called and the UpdateTextBox
methode is call on the UI thread the parameter e (EventArgs) does not
contain the derived MyEventArgs object but a EventArgs object.

Hello,
Serverside I'm generating a html page.
There are different controls for which I want to create an
eventhandler manually.
Like:
document.forms.TextBox1.onchange = EventHandler;
document.forms.Button1.onclick = EventHandler;

Okay, this is a rather complicated problem, so here is the short of
it:
I am using a custom designed user control that simply writes out a
plain old html submit button to the page. When the page posts back it
will randomly (I'm talking a few out of a hundred times) not catch the
System.EventHandler on the submit button click.
Here are the details:

Hi!
"CDemo.Call" eventHandler is added to "button3.click"
Event when both button1 and button2 are clicked.
However, I want to add "cd.Call" only one time even though
I clicked both button1 and button2.
For Example,
1. Click button1
2. Click button2

Is there a way to determine what has been added to the eventhandler list?
I have code that uses += and -= to turn event handling code on and off.
Apparently, it is possible to add the same event handler more than once.
Documentation refers to a Delegate invocationlist...but I can't seem to
access it from C#.
I am looking for a way to ensure that the contents of the eventhandler list
is "well known".

I have built a control that runs an on-line help system. Depending on the
category you selected via dropdownlist, it goes out and gets the child
subcategories, and if there are any, adds a new dropdownlist to the screen
for selection. This continues until there are no children, and then it
checks for a help article list based on that last selection and displays
actual articles for display.
Adding the controls and getting everything...

Can anyone tell me how I could iterate through a collection of controls on a
form while assigning their event handlers to another identical collection of
controls on the same form.
So far, thanks to another programmer, I've got this working out quite nicely
for the properties:
Type ctrlType = subject.GetType();
ConstructorInfo cInfo = ctrlType.GetConstructor(Type.EmptyTypes);
Control retControl = (Control)cInfo.Invoke(null);

Hae,
I have a windows form with a ComboBox an other things.
On that combobox I have an eventhandler on de selectedindexchanged.
But somewhere in my code want to do excecute the same code that is writen
in the eventhandler.
Is it posible to call that eventhandler from the code (not from a real
selectedindexchanged on the form). So, I don't have to call that code twice.

Hi there,
When removing page children controls created dynamically
not in last-to-first order, the close button of the last
control looses its event wiring, even though the handler is
rewired on each postback. It needs one postback roundtrip
to "get it back".
Form has an "add panel" button. Using it I dynamically add
3 panels with a remove button on each, A B C, to the page.

I've got a class to make Templates for different repeaters in my page. in one of these repeaters a linkbutton is needed. This LinkButton needs an event that is in a .cs file somewhere else in the website. (coz the event is used by other controls too) In the event some of the controls of that page ar accessed so I thought it would be easy to keep the Eventhandler there too.
My problem is that I cant seem to get the eventhandler to work. Basic...

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,...
