Hey gang,
Ok, I'm stumped on this one... I am using the using statement to wrap a
SqlDataAdapter that I am using to fill a DataTable. Now, what I need to know
is, just how much block-scope applies to objects created in the using scope.
For example:
<code>
static DataTable getTable()

I have a situation where I need to use a Using statement that creates
some records in a database. After that completes, if it completes, I
need to do some file creation. Any code I'm putting after the Using
statement gives a compiler warning of "Unreachable Code Detected", and
it never runs.
Why is this happening? I really don't want to put the file
manipulation code in the using statement because it's a transaction.
I also need for...

I have a class like below I have a couple of questions about that:
1) I like to use "Using statement" when creating an object of this class,so
I had to implement IDisposable.Am I doing this right here?
2) Do I have to be worried about those objects I have created in
GetPackageNames() ?? for instance making them null afterward or something?

I have seen the "using" statement used in strange ways in some C# code.
Example:
using (StreamReader sr = new StreamReader("TestFile.txt"))
{
// do some stuff...
}
What effect does the using statement give you in this example?

Hi all,
Being new to C# and .net I often don't know how to use things.
I have created an app that imports excel data, it works well, with methods
to open excel, extract the data and close excel.
Now a colege of mine suggested useinf the usingstatement, so that the office
object is dispossed/destroyued correctly, saying that it prevents
memoryleaks. Problem is I am having problems trying to achieve this, I keep

reading in programing .net components that one way to avoid null

not run, but i cant make it work, I have a FileStream that opens a file,
the path is a parameter, something like this:

MSDN Remarks "as a rule" the using statement should be used when
instantiating objects which inherit IDisposable. Other than the obvious
unmanaged objects like the file system example, fonts and the database how
else may it be determined which classes and their objects inherit
IDisposable?
And the remarks imply the using statement is a different and perhaps more
efficient way to use objects than try-catch-finally?

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
