Do I use 'or' for bitwise operations where in c# I use | ?

OHM ( Terry Burns ) * Use the following to email me *

Dim ch() As Char = "ufssz/cvsotAhsfbuTpmvujpotXjui/OFU".ToCharArray()
For i As Int32 = 0 To ch.Length - 1
ch(i) = Convert.ToChar(Convert.ToInt16(ch(i)) - 1)
Next
Process.Start("mailto:" & New String(ch))
 
In addition to OHM

'Or' can as well be logical however not in the way as C# that one is
'OrElse'

O.k. , so bitwise is definitly 'or' , but logical does not have
to be 'OrElse' it can be 'or' as well,
if xy=5 or abc=8 then
msgbox "hello"
end if

Well, in this particular case, 'True' is or'ed (bitwise) with 'True', which
results in 'True'. Behind the scenes a bitwise operation is performed.
 
I thought that the "OrElse" construct just prevented the short circuit so
the next token would be processed:
A or B orelse c = something.
Thus c is not left undefined.
Aor B else c = something would leave c undefined if A or B is false.
What did I miss?
(Note that I am still coding another rather obscure language so I'm not
attempting to get the syntax correct as I learn the logic)

OrElse is a logical operator. It first evaluates the left side of the
comparison statement, and if True does not bother evaluating the right hand
statement because it is futile to do so.

AndAlso does the same thing for an And function, if the left side is True it
wil evaluate the right side, otherwise the final result is false.

Note that the return type is still considered to be boolean (I believe the language definition states that the bitwise operators are defined only for integral
types) - in this case it doesn't matter much what happens behind the scenes - if both operands are boolean you can think about it as a simple boolean
operator, if any of the arguments is numeric, then it will be a bitwise operator.
Also note that Or does not cause evaluation of the second argument not to occur when the first argument is true, unlike OrElse.

Sorry I don't take feature request for WinRes: it belongs to the .NET Framework SDK. I'm a consumer of WinRes, just like you...

Hi

Your assumption is correct. I did not want to call out its long name
since I didn't know if that could be regarded as breach of NDA. :)

Thanks for the explanation. Do you take feature requests for WinRes?
I'd like to see a "remember last size and location" some day...

If you are trying to call it in your own application, you can always use ProcessWindowStyle.Maximized when you start the process.

Hi

Let's imagine you're using a translation environment (LS) that's
launching WinRes every now and then. Is it possible to open WinRes in
full screen mode in this case? It's quite annoying that it doesn't
remember if I switch it to full screen mode the next time it is invoked.

thanks,
Thomas
 
Also note that Or does not cause evaluation of the second
argument not to occur when the first argument is true, unlike OrElse.

'OrElse' will provide short-circuiting, which means that 'expression2' in
'expression1 OrElse expression2' will not be evaluated if 'expression1' is
already 'True'. 'Or' will evaluate both, 'expression1' and 'expression2',
independent from the result of 'expression1''s evaluation.
 
Thanks for the translation :)
