Have managed to create working MDI form and child windows etc.
Also added a callback from an unmanaged 'C' dll (ok that was strangely
easy to do and it works).
The callback simply creates a string form the callback char * data

help!
I have an unmanaged DLL that I do not have the source code, so i can't
recompile or make changes. the DLL requires a callback function. I would
like to implement the callback method in a managed class. The unmanaged DLL
gets the address of the callback in a struct (someStruct below) that is
passed as a parameter. I can't seem to figure out how to pass the
"unmanaged" address of a managed method to be uses as a callback.
I would...

Hello,
Newbie question here. I have a VS.NET 2003 MC++ (not C++/cli) project

Hi,
I have an unmanaged application that converts a function pointer to a
delegate and then pass this as a parameter(delegate) to a managed function
which then invokes it. Currently Im able to jump to this unmanaged function,
but the values of the parameters inside this function Im seeing are not
correct(they have some garbage values).

Hi,
I have my main application class(unmanaged) that has a none static member
function that I need to pass as a delegate to managed C# method.
In one of the methods of this class(unmamanged), I am calling a managed C#
method(I use gcnew to instantiate the managed class). One of the parameters
of this C# method is a delegate. I need to pass the none static member
function as a delegate(function pointer) as a parameter in the managed C#...

Hi,
I'm coding up an application that has a native c++ layer,
asynchronously calling callback in a CLI layer.
We originally did this with static inline methods in the CLI layer,
but this solution only works with singleton objects. So I have to
explore other solutions.
So beside pinning pointers, I've been looking at GCHandle. I was

I have an unmanaged library that can accept an instance of an abstract
class and call back into it. I'm writing a wrapper for this library.
How do I wrap a managed callback in a class derived from the unmanaged
class to pass to the library?
I tried creating a managed class that carries an unmanaged callback class
which calls back into the managed class, but I can't put a handle to the
unmanaged class in the unmanaged class. (I get...

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,...
