1. Does class shared variable share same feathers as ASP.NET application variable?
2. If it is, it may work better than application variables, because we don't need type conversion
3. Can web farm share same class shared variable? This is not critical for my case, just curious
4. I want to declare a ReaderWriterLoc k object for thread synchronization , should I declare it as public shared variable in a class, or an application variable
5. If I declare a public variable as Hash Table, I can put all my Thread Related objects into it. So I can create a new Thread, or Abort a thread any time. Is that correct?

1. Does class shared variable share same feathers as ASP.NET application
variable?
Static/Shared variables are shared amongst all instances of the app, session
variables are unique to the session.
2. If it is, it may work better than application variables, because we
don't need type conversion.
Memory allocation is also different. However the type of the session
variable is what it is, all you need to do is cast it to its type which
AFAIK isn't resource instensive
3. Can web farm share same class shared variable? This is not critical for
my case, just curious.
4. I want to declare a ReaderWriterLoc k object for thread synchronization ,
should I declare it as public shared variable in a class, or an application
variable?
5. If I declare a public variable as Hash Table, I can put all my Thread
Related objects into it. So I can create a new Thread, or Abort a thread any
time. Is that correct? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I find an interesting issue that one base class has only one copy for
each derived class. It looks like that one base class will be copied into
three base classes while derived class from base class is executed. It
means that three derived classes are pointed to a separated copy of base
class. I do not allow second and third copy of base class to be created,
but it must remain only first copy of base class.
It allows three derived...

Hi,
I don't get the difference between a struct and a class !
ok, I know that a struct is a value type, the other a reference type, I
understand the technical differences between both, but conceptually speaking
: when do I define something as 'struct' and when as 'class' ?
for example : if I want to represent a 'Time' thing, containing :
- data members : hours, mins, secs

Hi,
How can I declare a variable in a Class so that it can be accessed from the
page that calls it? Normally I would declare a variable outside a function
so that it can be used globally on the page but I'm not sure how to do it
in a Class. I tried using public but that didn't work. I have the following:
Public Class dataClass
Public Shared Function GetRep(ByVal prodNumber As Integer) As
DataSet

Hi guys (and gals!),
I've got 2 classes, "TypesafeConstant" and "Color". "Color" inherits
from "TypesafeConstant", and adds no new functionality. All "Color" does
is to instantiate some class variables which are public instances of
"Color".
What "TypesafeConstant" does is to create a shared list, and add every
declaration of itself to that list. I can then query that list with a
string (e.g. "Red") to return Color.Red.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
