From what I see you get the schema for the container which maps out the organization like a xml schema.

i got it:
schemanamingcontext = schemanaming "container"
man, "context" is confusing, they really should named it "container" instead

yeah ms and thier hype words
securitycontext = securitycontainer for the object (DCOM)
MTScontext == the container for the MTS object thats acts as a proxy much like Eneterprise Java Beans
need I go on...
now that I think about in my COM+ book for c++
COM+ wraps every thing with a container to proxy calls and what not and they call that...guess... ObjectContext
go figure

"context": something of interest resides in contexts (make sense doesnt it)
After you explaining it, I begin to look at the word "context" (and the world) differently: context==container. or more precisely, container==context (gee, that feels a lot better now)

funny though how I didnt undertsand that I did understand so-called "Context"

 Guys,
How can I call a c++ function from c#?
Many other sites say "call it as a DLL using InteropServices", but this seems like hard work. I have a single solution with two projects. One is in C++ the other is in c#. Why can't I just compile them together and have the linker resolve the references between them.
People are suggesting that you can't do this at compile time - only at run time via a DLL. But that seems crazy. Has anybody worked out how to do it>

Leppie,
So I think that you are saying that the only way to do this is at run-time - is that right? I am suprised that I can't declare a C++ function as public and have the linker resolve across the two languages.
I have given up trying to learn Microsoft C++, I think that the compiler are environment are awfull. When ever I try to use it I end up spending days trying to understand bizare error messages from the compiler or linker that give very few clues as to what might actually be wrong with the code. I am much happier with c#.
Regards
Rob

just expose your C code as managed C++ lib, then Add Reference. i think if you know what you're doing, it's like a hour's work. If your c++ code is managed code, just compile the "managed c++ class library". If not, just cut and paste your c++ code into a managed c++ class library - then compile and get your dll/assembly. After that, you have two options:
1. shared dll (you need to install assembly into GAC - perhaps forget it for now)
2. private dll (That's what you will do, for now)
With option 2, just do this:
1. Project menu
2. Add Reference
3. Browse (select your dll/assembly)
Then, just use it in your c# code:
using namespace XXXXX;
...
...
MyCPlusPlusClass obj = new MyCPlusPlusClass();
...
Just in case you get confused... in your managed class library (which compiles to dll):
namespace XXXXX
{
public class MyCPlusPlusClass //REMEMBER "public"
{
//your stuff
};
}
I don't think you need interop. YOu didnt develop a COM/ATL-server. For newbies, what I described is easiest and it's more efficient (by passing layers of framework code). But, if you wish to explore:

Sorry, won't work. In managed C++, class is equivalent to __nogc class, and only __gc classes can be seen from C#.
Like leppie said, I would just create a MC++ wrapper for the functionality I want to expose. For a general idea, take a look at facade design pattern[^]

Why are you surprised? In order to use a type between languages, it must be CLS compliant. C++ functions are not CLS compliant.

I can't imagine why.
Why can't you rewrite the function in C# ?

Hi,
I'm amost finished creating my first C# application 
My application connects to a database and I want to be able to change the connectionstring without recompiling.
I have read about the app.config file but I'm having problems making i work 
Are there anybody who has some tips, examples or useful links?

Your configuration file should be named application.exe.config. Replace application with the actual executable name. If you add the configuration file to the project then name it app.config and VS.NET will automatically rename it correctly when it builds the project. The file should look like...
<configuration>
<appSettings>
<add key="ConnectionString" value="the actual string goes here" />
</appSettings>
</configuration>
And in code you can access it with...
ConfigurationSettings.AppSettings["ConnectionString"]

I am using Async Sockets and ThreadPool in order to accept data from a client at high speed. My code works flawlessly on my dev machine XP Pro, and also my Win2K Server test box. However it does not work on the server where it will be running. I have tracked the problem to the function being passed into QueueUserWorkItem not being called.
Has anyone ever come across this or have any idea what might be happening?
Thanks in advance

are you running your application from inside your visualstudio IDE ?
try to start from the .net command prompt.
the application i'm writing at the moment (also dealing with sockets and threads) also misbehaves when i start it from inside visualstudio.
don't know why.

What do you mean by "the function being passed into QueueUserWorkItem not being called"? The program hangs or it "skips" the call, as if it was not made?
If it's the case of hanging, don't forget that the ThreadPool have a limit of 25 threads per processor.
I hope that you have money because it’s necessary to be practical.

It's ok guys, thanks for the replies. I found out what was happening. Basically a dll that contains a data holding class was apparently the wrong version which I discovered indirectly. Without this other app I would never have discovered the problem due to something catching uncaught exceptions in a C# Windows Service. Here's another one though, does anyone know why uncaught exceptions from a service do get caught somewhere and not logged?
Thanks again guys
