Sorry to hear that. Direct bitwise with the various operators is one of the few remaining weakness of VB.

I am confused here, i thought it did!
dim a as integer = 15
dim b as integer = 3
dim r as integer
r = a and b
' r now = 3 isnt thsi what you want?

There will be some more bitwise operating I thought or better there is
already, however you knows this better to me, so I think that this
explanation is to short.
(As well for me of course, to clean maybe a misunderstanding from me)

No, he wants to use Binary literals in his expressions like with hex for
example, &HFF. He wants to write %11111111

The only thing I can suggest is that you write a class for converting binary
represented string values into shorts something like.
PSEUDO!
Class ConvertMe
Public Function ToShort( ByVal str as String ) as short
Dim c as MyShort
'Get the string is valid
'Else throw an exception
For each c in str
MyShort << 1
MyShort = MyShort And ValueOf( c )
End Function
Return c
End Class

Sure, but there will not be binary number literals, like '&B10010101'.

I am currently discussing with some folks about this idea. Basically I
like it, but there are problems associated with it too. Consider this
code:
\\\
If (Foo And &B11101010101110101011101010010010 = &B11101010101110101011101010010010 Then

Herfried,
I normally use: <Flags()> _
Public Enum Goo
None = 0
A = 1 << 0
B = 1 << 1
C = 1 << 2
D = 1 << 3
End Enum
Where the 1 is shifted over the bit position.
I agree I've wanted binary constants once or twice.
Just a thought

No it's Pseudo code.
Basically what I am trying to impart is that you could construct a number
from a string representing a binary number so in your test u could have
written.

It's pseudo code, or in other words, a method that takes a string
consisting of "0" and "1" characters. 'ValueOf' would return its
integer value.
Still, performance will be bad, especially for longer strings. Natively
supporting binary number /literals/ that are converted at compile-time
would be a far better approach.
Currently, you can use this code to get the behavior of 'ValueOf':

Full ACK. I prefer this way too.
I agree I've wanted binary constants once or twice.
I just throught in which situations binary number literals would make
sense, and the case of a little enum was one of the most useful cases I
was able to find. So, in everyday programming, binary number literals
don't make much sense, which still doesn't mean that it should not be

Yes, I agree completely, however, in the absence of those binary literals,
if the OP wanted to be able to write out a string of ones and zeros in the
programming then this is one option available now.
Given that Visual Basic, has little support for accessing the pc's IO, its
probably not much of a requirement.

Actually, it's one of those things you almost never want to do, so I was
suprised that this overloaded ToInt32 had no less than ( 19 ) overloads and
one of them did the trick, well spotted H.

I quickly knocked up this implementation. However, as H pointed out,
Convert.ToShort("000000000000100",2) Does the same thing and I tested the
performance, its four times quicker than my code as you might expect. But
here it is for interest sake.
Public Function ToShort(ByVal str As String) As Short
Dim x As Int16
Dim i As Int16
For i = 0 To 14
If Char.GetNumericValue(str, i) = 1 Then
x = x Or &H1
End If
x = x << 1
Next
Return x
