i have a quick question... is there a way to obtain the reference to the
object which called the currently executing method?
here is the scenario, i have a class and a field which i would like to
populate with a reference to the object that constructed this current
object. i would attempt to accomplish this by setting the appropriate
field from within the constructor...
i figured it might be obtainable from the stack trace, but that...

I'm studying Nigel Chapman's Late Night Guide to C++ which I think is
an absolutely fantastic book; however on page 175 (topic: operator
overlaoding), there the following code snippet:
inline MFVec operator+(const MFVec& z1, const MFVec& z2) // Global
function
{
MFVec res = z1;
res += z2
return res; // WHY???

Hello,
This is a simple question for you all, I guess .
int main(){
double *g= new double;
*g = 9;
delete g;
cout<< sizeof(g)<<" "<<sizeof(double)<<" "<<sizeof(*g)<<" "<<*g<<" "<<endl;
*g = 111;
cout<< sizeof(g)<<" "<<sizeof(double)<<" "<<sizeof(*g)<<" "<<*g<<" "<<endl;

Hello!
After I've finished using an instance of the SqlCommand class, should I then
invoke Dispose() on the instance. I suppose so, as there is a Dispose
method, but what does it actually release?
I would basically prefer to skip invoking Dispose() as this will free me
from determining when the usage actually has finished.

Hi All:
I am creating a COM+ Pool object in C#. I set up the following attributes:
JIT (true),Pool size; and at the end of each public method I called
ContextUtil.DeactivateOnReturn=true to set DONE flag; and also I override
CanBeBooled method to true.
In my calling program in C#, first of all I am using NEW to create a object,
then I call the method then I call dispose.

I have a web application with impersonate=”true” in Web.config and on my own logon page I allow the user to either
- specify a userid/password for the app to impersonate when calling legacy COM objects
- or, just use the interactive user
If they choose to use the interactive option, the impersonate="true" means that the process runs under the interactiv
user (which I've confirmed works correctly). If they specify a userid/password, I...

I'm trying to utilized a more object-oriented approach to managing
window events in javascript. Thus, I am creating a "controller" object
to handle events and interact with the server. However, I apparently
don't fully understand what "this" refers to. In the code below I was
expecting that when the button was clicked (handleDeleteButtonClicked
function) that "this" would be pointing at a ViewController object.
Instead it was the Button...

We have a project in .NET 1.1 , some of the .NET methods take COM
interface reference pointer as a parameter, somehow we have to call
Marshal.ReleaseComObject to release the COM Object, otherwise the COM
object will never get release, Even we call gc.Collect()
But the same code compiles in .NET 2.0 works without the
Marshal.ReleaseComObject. (Unfortunately the project is supposed to
run on .NET 1.1.)

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,...

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...
