Hi All,
Is it possible to export a c# method into a dll in such a way that your
"normal" C application can then call this method?
To be clear: I am not asking how to use "DllImport" or PInvoke. My
question is the other way around.
Regards
Pieter Breed

Hi,
I hope you can help me understand the varargs facility.
Say I am programming in ISO C including stdarg.h and I declare a
function as so:
void log_printf(const char* logfilename, const char* formatter, ...);
Then, I want to call it as so:

does calling a regular function cost any cpu time? In other words, is it
faster to write the code of two functions into main(), or is it the exact
same thing as calling two functions. I know its nitty gritty but its
necessary for my program.
thanks

Yesterday I posted the message below to microsoft.public.dotnet.languages.vb
and microsoft.public.vc.language. The two replies are also posted.
I need to write some ISO C++ functions, more information below. Is C# a
better language to use than VB.NET for calling these C++ functions? If so I
would appreciate some links on calling C++ from C#.
Thanks!

Hi all,
I'm trying to make a plugin DLL for a third-party application, using
VC++ .NET 2003. This DLL acts as a bridge between the C++ plugin API of
the application, and my actual plugin code written in C#.
When the app calls my unmanaged functions, they work fine. But as soon
as my unmanaged functions call managed functions (in the same source
file!), the app reports an "unknown exception" error.

Hi,
I need to make a function that can display data on my Managed C++ app and be
called by an unmanaged C++ DLL. Something like :
void Form1::Form1_Load(System::Object * sender, System::EventArgs * e)
{
MyDLLInit(MyAppDisplayFunction);
}

I'm using a library called fyba. This library reads and writes files in a
format called sosi. fyba uses the following code to determine if the
calling process has own methods to handle errors, messages, etc:
// If this parameter is NULL,
// GetModuleHandle returns a handle of the file used
// to create the calling process.
hInstExe = GetModuleHandle( NULL );
if( hInstExe!=NULL )

My problem: I need to call (from C code) an arbitrary C library
function, but I don't know until runtime what the function name is,
how many parameters are required, and what the parameters are. I can
use dlopen/whatever to convert the function name into a pointer to
that function, but actually calling it, with the right number of
parameters, isn't easy.
As far as I can see, there are only two solutions:
1) This one is portable. If...

I'm a C# developer and I'm new to Python. I would like to know if the concept of Asynchronous call-backs exists in Python. Basically what I mean is that I dispatch a thread and when the thread completes it invokes a method from the calling thread. Sort event driven concept with threads.
Thanks.

Hi,
the following is the definition for calling convention ,which I have
seen in a text book, can anyone give a more detailed explanation in
terms of ANSI - C
"the requirements that a programming system places on how a procedure
is called and how data is passed between a calling program and
procedures are called calling conventions"

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

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,...
