Enums, atleast the .NET version, are pretty bad OOP IMHO. No inheritance, no
polymorphism, just flat value with a type.
Indeed - bring on the Java enumerations! (They have a few wrinkles, but
generally they're incredibly handy.)

I have to agree, I'm starting to like some of the advantages more and more.
Although I don't think traditional inheritance is going to happen within the
..NET framework(chang ing enums from value types to reference types is a huge
change), allowing method definitions, including a basic set of operations
like IsSet(), Set(), and Unset() for [Flags] enums, would certainly help
alot. Some form of enum composition might not be a bad idea either.

I'm want to give the user a set of choices that will present themselves
as an enumeration in intellisence. It would be easier to write the code
if the values of the enum could be read from a file. I suppose a macro
can be written to help write the code.
Intellisense is a compile time thing, built entirely on static code
knowledge. It doesn't make sense to change things at runtime and expect
them to change at compile time as well. Are you trying to generate code
files?
I think that is the only option with .NET. COM seems so much more
powerful than .NET.

Come again? I don't really know what you are trying to achieve, let alone
waht you mean here.

Can't add to those dynamically either (At least in any supported way. I
haven't tried to hack into the $VALUES array.)

No, you can't add to them - but they stil have fabulous advantages
compared with .NET enums.

Hi,
I want to populate my Enum dynamically from the database. Is that possible?
If so, what is the approach that I need to take.
I need this because I have some set of constants in my table which I want to
fetch once the moment i start my application and store that in Enum.

Hello
In VS2005:
I am adding buttons and textboxes dynamically into a table, that also
dynamically expands.
So far, so good, actually very nice.
But I am having trouble starting the desired subroutine on postback. To me
it seems like the button click event looks for a client script instead of
going to the aspx codepage and execute the sub there.
The same thing happens with textboxes, where I programatically add

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.
