Hi
I want to find out what objects are due to receive an event i.e. those
that have added themselves as an event handler via +=. Yes, it's a
little pointless perhaps (or can anyone give some good uses for
this?!!).
How do I do this for an event on a class I implement? Also, how may I
do this for an event in the .Net framework e.g. a...

In VB 6, the Form_QueryUnload event had an UnloadMode parameter that let me
find out *why* a form is unloading, and then conditionally cancel the event.
In VB.NET, the Closing event passes a CancelEventArgs that lets me cancel
the Close() operation, but is there still any way to find out *why* a form
is closing?
This app as a form that...

I've upgraded my code to VS C++.NET 2005 (Express) using /clr pure. My
question is, why is there an exception to the rule in how pointer syntax is
done in the event handlers?
For example, why is this proper syntax:
button->Click += gcnew EventHandler( this, &MyClass::MouseHandler ) ;
The '&' seems like a hold over from the old syntax,...

I'm trying to get my head around what's involved in C# to declare, raise and
respond to an event.
I'm coming from the VB.NET world where to declare and event we wrote:
Public Event Foo()
To raise the event, we wrote:
RaiseEvent Foo()

I am just getting started with events and had a couple of questions on why
they do what they do.
If you have a textbox and you want to handle an event you can just do:
this.TextBox2.TextChanged += new
EventHandler(TextBox2_TextChanged);
and then have the function.
void TextBox2_TextChanged(object sender, EventArgs e)

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. ...
