Hi, anybody can help me with this.
I've created a singleton class, and now wants to add destructor to it.
I know we can implement the IDisposable and also overrides the Finalize
method (from the MSDN example). But is it possible that we just implement
the Dispose method, which we will call at the end of the application?
Will there be any memory leak or side effects?

I have an application that creates a class. The class has unmanaged
resources, so must end gracefully.
How can I guarantee that the unmanaged resources are freed?
I have looked at IDisposable, but this seems to rely on a call from the
application, e.g.
MyClass.Dispose()

hi,
I have a component that uses a database connection.
In the finalizer I dispose the connection because I read in msdn the
following:
"A type must implement Finalize when it uses unmanaged resources such as
file handles or database connections that must be released when the
managed object that uses them is reclaimed."

I still don't really 'get' this. Why can't an object just release its
resources in its Finalize method? Why when I create (eg) a Graphics
object does it become *my* responsibility to say when I've finished
with it, and explcitly say so? I thought one of the points of managed
memory / garbage collection was that users of objects didn't have to
worry about tracking object lifetime?
What's the point of me saying g.Dispose at the end of my...

I started to use the Finalize sub in aspax page, I put a break point on one
of the lines, hit run with debug, the pages dispalys without breaking on the
line.
2nd question, do we need to use the keyword "set" as normal vb to set an
object to nothing or it is enough todo the following
"myobject = nothing"
instead of
"set myobject = nothing "
Thanks

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,...
