Using c++ dll, c# project and a com object together

i have need to use com objects for the inter process communication purpose.

In my project i have created

a c++ dll,

a c++/cli interface for using that dll in c#

and my project is being developed in c#

now i need to use com objects(for inter process communication purpose in windows system) but i am not sure how i can use them with my existing project model.

i am learning how to create com objects and all, but having difficulty understanding how can i use them with my existing project model, all the sources i found seems to suggest how to create a new com object and then use it etc.

to further clarify my question : i want to use com interface with my existing c# project instead of creating a new project from beginning.

do i need to modify my project or any other ideas are appreciated.

i am new to com objects and learning it now.

Exactly what problem are you trying to solve? Why did you create the C++ DLL in the first place?

i created the c++ dll because i need to use the speed and flexibility of low level interface provided by c/c++ language.

can i register my whole project(with given project module) with using com objects or something like that.

If speed is what you are looking for, then try to stick with C++ only. Why are you merging every platform available in your project? Visual C++ would be what you are looking for here.

As to your second line, everything is possible. It depends on how you go for it.

See https://www.google.com/search?q=COM+in+c%23, for some samples and tutorials on using COM objects from C#. Get rid of the C++/CLI interface, it just complicates things.

i don't have option to get rid of c++/cli dll, is there is a way to work with it

Of course you do. You can do it the way Microsoft designed it, so it works. Or you can play around with multiple frameworks and suffer pain.

It will be clearer if you get rid of the cli-stuff and only use a C++ which gets called from C#.

It is quite simple possible, as I wrote an article and demo code about it.Also this article is worth reading even it is the opposite way, if you consider modiying your com.

Create your com-objects as global object pointers.
