I understand how to do the ENUM, but I don't understand
what the values are?
They are in hexadezimal format. Use '&H1' for '0x0001', '&H2' for '0x0002'
and so on.
2.)

if (_cardTypes & CardType.Amex)!=0)

where _cardTypes I believe contains some bitwise combination
of the CardTypes from above.....

Use 'If (m_CardTypes And CardType.Amex) <> 0 Then' instead.

Tom,

Hmmm... So the All = in #1 below would use the 'Or' versus the 'Xor'? Does
a standard Or make ALL a unique ENUM? Or is that doing something slightly
different in VB, than in the C#?

I will try it! Thanks for the assist.......

Hi James,

VB's AND is a bitwise And and OR is a bitwise Or. They are the same as
their C# counterparts.

If you come across && in some C# code, it is the same as VB's AndThen.
Similarly C#'s || is the same as VB's OrElse.

'AndThen'? Typo or am I missing something?

'AndAlso' and 'OrElse' -- IMO very nice. I would have liked 'And' and 'Or'
as logical operators and 'BitAnd' and 'BitOr' as bitwise operators, but they
changed that in the Beta.

Hi Herfried,
Of course, first of all, which VB programmer uses those really often.

We always agree that the natural language prefers, I seldom say "en ook" do
you say often "und auch" ?

That renaming bitwise operators had been a good sollution. And fits to the
theorie of natural language. Bitwise is not a part of the natural language
and for that you can create a new word.

That's exactly what I think.

Yes.
The value of ALL will be &H7F in #1
Or is that doing something slightly

I think they are same in the bitwise operation.

You may check the link belwo for more information.

Used to perform a logical disjunction on two Boolean expressions, or
bitwise disjunction on two numeric values..

http://msdn.microsoft.com/library/de...us/vblr7/html/ vaopror.asp

Binary | operators are predefined for the integral types and bool. For
integral types, | computes the bitwise OR of its operands. For bool
operands, | computes the logical OR of its operands; that is, the result is false if and only if both its operands are false.

Hi Herfried, Cor,

'AndThen' is how I think of 'AndAlso', which is somewhat awkward English
as far as my usage of it goes. Like "und auch", the also doesn't add anything
unless you're emphasising - "... and another thing...."

I would prefer BitAnd and BitOr to emphasis the bitwise nature of the
operation (and unsigned values to use it on) but changing the semantics of And
and Or would break a lot of code until the programmers writing/upgrading it
had a firm realisation of this radical change.

Ah, well,

Regards,
Fergus

Hi Fergus,
Some weeks ago I was arguing about that in the newsgroup and told that in
Dutch (translated)
"en ook" is unusual and only used to give an extra dimension to "and". But
it is in normal Dutch awkward.

Some regulars from England and the US said that it was normal used English
but I did doubt it, because in using key words, Dutch is in many ways quiet
similar to English. But they said: "no it is well used English!"

Herfried said too that it was normal in the German language, that I can
absolute not oversee because in the German language are a lot of words quiet
similar with Dutch but it is grammatical totally different. The grammatical
seems to be from the bible from Luther, what was in the language from the
people from the mountain like Herfried.

And now you come with this sentence.

'AndThen' is how I think of 'AndAlso', which is somewhat awkward English as far as my usage of it goes. Like "und auch", the also doesn't add anything unless you're emphasising - "... and another thing...."
My first characters I did type were "Fergus I love you".
:-))
I would prefer BitAnd and BitOr to emphasis the bitwise nature of the
operation (and unsigned values to use it on) but changing the semantics of And and Or would break a lot of code until the programmers writing/upgrading it had a firm realisation of this radical change.

Make sense but I think that the most VB programmers avoid using bitwise
programming. I think 95% does not know they exist and 98% not how it works.
(Only my opinion).

Gives me a good feeling that I was not arguing* with only stupid arguments.

That is the same as in Dutch (with other words for "and" and "also" and

AndAlso the answer were totaly oposite.

I'm sure that you argued* your point well in that discussion against your
countrymen and also** against the English speakers.

Even when I first started using BASIC I was into bits. But then I
discovered C and moved camp.
