I'm trying to plan a separate mechanism for extending an existing COM add-in
architecture so that at run time a separate code branch can be taken if a
desired COM object is managed rather than unmanaged.
I know that mscoree.dll is listed for managed dlls, but is there any other
way to determine

It was the calling convention that had the application acting bizzarre.
After decorating the c++ callbacks with __stdcall the void callbacks worked
as expected. Changing the c# delegate to use all IntPtr for the c++ char*
callback worked as well. Now I am just down to figuring out how to

Ok, in an effort to discover WTF... I added a couple of void Callback
functions to my c++ dll and I can get one of the void call backs to actually
work in the c# application. However the wrong void callback is being
called. What gives? Are the function pointers getting touched/changed by
the GC

No one said it's trivial. And you're trying to use one of the more
abstruse cases -- invocation of managed delegates from unmanaged code.
You still need to step through the assembly, to see exactly what is
happening. The unmanaged C++
What you're probably looking for is

I get no exceptions, the callback is simply never called. FYI, this works
fine from a c++ app so the DLL and the callback mechanism are fine. I just
can't get it to work with c#. This interop stuff is not as easy as they
claim it to be.

Wow, that must be the most verbose possible rewording of "shove the data
back along the wire like any normal client-server app. TCP/IP does a pretty
decent job of buffering, fragmenting, and reassembling data."
More seriously, Andrew, I'm curious for your take on Levente's original
claim that h
Hi Martin,
The function pointer should also have a stdcall 'annotation'.
The WINAPI define from windows.h can be use for this.
declare your function pointer like this
typedef WINAPI bool (*LPFN_CALLBACK)( const char* sz1, char psz2[], unsigned
long*
pulsz2Length );

1) Make sure you handle the calling convention correctly. As far as I
know, .Net only supports using the __stdcall calling convention. So
make sure that LPFN_CALLBACK is declared using __stdcall. Otherwise, if
your C++ code is compiled with a different default calling convention,
then when the u
I have a c++ dll that exports a function that takes a function pointer (
callback ) as a parameter. This function ( callback ) takes 2 char*
variables as parameters. How do I prototype the c# delegate to successfully
have the delegate function called from within the c++ dll? I am getting

I think ADSI is your best bet, using the System.DirectoryServices classes,

I agree with Jade's assessment. The

describes the .NET strategy. From the docs:

It sounds like you should be able to get by with just implementing
IDeserializationCallback in the base class (and just sticking to
[Serializable] and *not* implementing ISerializable). Your implementation
of OnDeserialization would then just initialize the refcount field as needed
to fix it up.
