Hi All,
I don't know whethher this is possible or not. This is the result of a
bad design problem.
Here I go; I have a structure like this:
typedef struct _s_index_entry {
char *doc_id;
double s_id;

Hi people
I am wrapping a C dll using PInvoke from C#. I need to wrap the following signature in C
int dma_start( const UCHAR* data, UINT data_length )
The function should start with a DMA operation, and I have to use it from my C# program. I am really unsure what type of marshalling I should use.
The data parameter is a pointer to an array of byte data. This data must not be copied when calling the function. Plus, the .NET...

I know this functionality already exists in .NET 2.0 via
Marshal.GetDelegateForFunctionPointer, but I'd rather not force my users to
use a beta framework (not to mention the fact that I'm still using good old
vs .net 2002, that refuses to use the 2.0 framework).
Specifically, I'm using an external declaration of the Simple Directmedia
Library function SDL_GL_GetProcAddress to acquire the procedure addresses
of OpenGL extensions. ...

I am calling a C/C++ DLL from C# and I am marshalling the parameters to the
API call by doing a type conversion for each parameter.
For example, here is my C++ API method :
short int XENO_API XcDatabaseCodes
(
HWND hwnd,
char FAR * pszDatabase,
char FAR * HUGE * FAR * pszItemCategories

Greetings,
When working with managed c++, do you have to do anything special when going
from simple types from managed to unmanaged and vice versa. Or is
marshalling handled automatically for you?
I have seen from several posts that you have to do special conversions for
strings, but what about the other types such as int, long,ect. In my case I
want to save it as a member variable from a managed class into an unmanaged
class's.

Hi all,
I'm taking my first steps into C# <--C++ DLL Interop and
unfortunately I've run into (what seems to be) a very complicated case
as my first task. Perhaps someone here can help me.
I need to pass an array of RADIO_INFO2 structures to be filled by a
function in the DLL. This is how the structure is defined in the C++
example that comes with the DLL:

Hi,
I'm pretty sure I've just got a Marshalling problem, but I'm
completely stumped. If there is a better newsgroup to post this in,
please point me towards it.
First I'm trying to use SendMessage() with WM_COPYDATA to send a
string data between two instances of a program. As part of the
debugging I've written two methods one where a given instance will
obtain its own hWnd and send itself the message, one where it accepts

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...

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,...
