Folks,
Stroustrup indicates that returning by value can be faster than
returning by reference but gives no details as to the size of the
returned object up to which this holds.
My question is up to which size m would you expect

I have a DropDownList that is returning the value from index 0 regardless of
which item is selected. The code that I am using to test which index it is
returning is:
Label1.Text = ddlDeleteEvents.SelectedIndex
This is the first line of code in a Button's Click event handler, so I know
that there is no other code changing the selected value before I use it.
What is happening here? Any help would be appreciated. Thanks.

Hi,
I have a generic list with a some objects of a particular class in it.
I have implemented a IComparer for the the class and pass it to the
List.
The list.sort method works fine when the value of the field I want to
compare is different, but when all the elements are same, the list
still gets sorted(meaning the sequence of the elements still change).
For eg.
Say the list is filled with object of type A, where in A has a

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:
