I'm a self-taught programmer, so this might be a pretty dumb question.
If it is, please point me in the right direction and I shall
apologize profusely.
I have a question regarding C++ and object members. Can anyone help?
I'm writing a C++ wrapper for a fairly old programming interface to a
document editing program that has no OOP whatsoever; only tons of
structs. This program has different callbacks I'm supposed to
implement for...

I've to invoke a unmanaged dll fucntion in C# which uses
a callback fucntion.The unmanaged dll fucntion returns a
pointer to a structure to its callback fucntion.The user
should collect those structure fields in a buffer.
In my managed code(i.e. in C# program), I've used a
delegate for invoking callback function and I've declared
the structure too. The dll fucntion is executing finely
without any errors but I'm not getting any values...

Hi.
I imported a .dll in my C# code and call a C function that takes a
struct of pointers of functions as callback functions. It seems to work
fine (the callbacks function wrote in my C# code are called) for this
part, but then crashes.
When it crashes Visual offers me to use a debugger, but the current
instance of visual can't be selected (only "new instance of visual C++")
and if I choose "new instance" it says another debugger is...

For some reason it appears that garbage collection is releasing an object
that I'm still using. The object is declared in a module and instantiated
within a class that is in turn instantiated by the mainline. The class that
instantiated the object in question is definitely still in existence at the
point garbage collection swoops in and yanks it out from under my processing.
Is there a way to ensure an instantiated object cannot be freed...

Hello, all,
I have a .NET application (VB) that passes the address of a delegate to
unmanaged code in a DLL. The unmanaged code then uses the delegate as a
call-back.
This seems to work fine, but now I am worried about garbage collection.
I am concerned that the location of the delegate might be altered as
a result of other (unused) objects being garbage collected. This would
probably cause undesirable results when the unmanaged DLL...

Hi, I could use some help in setting a C# callback function that an
external unmanaged dll will call on a event. Using a delegate and use
the external callback set function doesn't work.
The carbage collector says hello here (-;
I have pasted some code below, any help is greatly appreciated!

I have a Class OutlookObject, It have two private variables.
Private Microsoft.Office.Interop.Outlook.Application _Application = null;
Private Microsoft.Office.Interop.Outlook.NameSpace _Namespace = null;
The Constructor:

Hi all,
Is garbage collection possible in C++. It doesn't come as part of
language support. Is there any specific reason for the same due to the
way the language is designed. Or it is discouraged due to
some specific reason. If someone can give inputs on the same, it will
be of great help.
Regards,
Pushpa

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,...
