Hi all,

I realy thanks for guy about anything mention in:
http://www.codeproject.com/KB/atl/SimpleATLComWithDotNet.aspx

But in this tutorial just mention about adding METHODS into COM/ATL DLL and use it in C#....and didnt mention about adding FUNCTIONS.

i tried to add a FUNCTION but unsuccessfully. Can you tell me the way to adding FUNCTIONS into COM/ATL DLL and can use it in C#.

if you dont mind, give me a brief example.

thanks all

@Samer Abu Rabie: thanks im reading it now
@Christian Graus: i dont want to give concept about Function or Method, but in my situation i write a method and a function in same class, i build it into DLL and use in C#. But when i use this class C# just recognize the method and not function.

@Christian Graus:I have just learnt COM/ATL DLL though this Tutorial:A Beginner Tutorial for Writing Simple COM/ATL DLL and Using it with .NET [^]
and that's all my knowledge about it.

Here my sample code: http://www.mediafire.com/?wgmzmjoyxyk[^]
solution ATL_SimpleSample: create ATL DLL file, my function and method in math2 class(math2.cpp)
solution CallATL: to use DLL file,please see program.cs file. i can use Multi method, but MultiReturn function.

When you add a method ( a function is the same thing, sorry, I have no idea what you're talking about ), so long as it's exposed on the COM interface, you can import it and call it. I don't know if p/invoke works with dll methods in a COM dll. If you have some concept of how a method and a function are different, you're probably wrong, but you should edit your post to explain what you mean, so we can answer you.

I'm sorry, but 10 years of experience as a developer, including quite some time with COM, and apart from the possibility that you think it's a function if it does not appear in the interface ( which is false ), I have no idea what the hell you're talking about.

Like I said, I am not sure that a COM dll can have the methods not on it's interface called via p/invoke, which is surely what the other guy linked to.
