I've been doing some reading about Finalize and garbage collection.
I've learned that finalizing should be avoided because objects that
have a finalize method require 2 (possibly more) itterations of the
garbage collector to run before the memory is returned to the heap.
The first time the GC runs the Finalize method is called, then the
second time the memory is actually freed.
The problem is that most of the major classes in the .NET...

I have inherited some code and I am debug some connection pooling
errors. Is there anything wrong with the implementation of this class?
I am just curious about the empty destructor and implementation of
IDisposable as I have never seen this done before.

Hello...
I'm trying to make a database access class for an asp.net
application. When I run my application, the Garbage
Collecter doesn't seems to unload the memory attributed
to my SQLConnection. My db access class has a method
that returns a dataset and one that executes a non-reader
request. It also has a dispose method (to release the
connection) that I call in the finalize method of my aspx
pages(as learn in "Implementing...

When implementing the Dispose() method, I understand that it's supposed to
do what Finalize() does so that's why it should call GC.SuppressFinalize().
However, it's not clear to me what happens the instance itself, for example
in the following code:
public class Test1 : IDisposable {
public string Hello() {
return "HEllo";
}

The System.Data.SqlClient.SqlConnection has Close() and Dispose() methods.
So I started using Dispose() on my SqlConnections after I Close() them.
I've started getting into the habit of calling Dispose() on every object
that has a Dispose() method on it, after I'm through with it. I was just
wondering if it's safe to assume that if an object has a Dispose() method
you should always call it when done with it? Or am I just making more...

Hi NG,
I am not sure to evaluate what happens if I call the
GC.SuppressFinalize(this) for a object.
My question is:
In case I call GC.SuppressFinalize(this) from with in one of my object, do I
then have to somehow - if yes how - release instances created in the
constructor manuelly?
Simplified example:

I'm trying to understand the IDisposable pattern. In the sample on MSDN they
have added a destructor/finalizer like this:
~MyResource()
{
Dispose(false);
}
Calling Dispose(false) will only dispose non managed resources. If I
implement IDisposable only to dispose managed resources isn't this finalizer

I have a list box on my form, but I need to databind it to a data table that
is a private member of the form's class... so I basically have
Public Class MyForm
priate m_MyTable as new datatable
End Class
now where would I properly dispose of this? In the finalize method? I am
loading the data for the table in a subroutine that is executed at form
load, of course all the commands tied to it are wrapped in using blocks, but

I feel i still do not understand maybe a bit a dispose pattern
So I have a question - is this code right? Is fs.Close() there where
it is right?
If I do understand it in place 'BBB' there can be a situation where
such member
obiect as fs can be finalised - so it may be wrong. Am I right or not?
But if i would close fs in place 'AAA' then I am not sure if a user of
this class
called a dispose() on it ? Am I wrong or right?

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:

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,...
