can I create a out of process WinRT component through C++/CX?

Question

I see the sample using WRL create out of process WINRT component, but WRL looks too heavy for me.

Does anyone know how to create a out of porcess WinRT component throw c++/CX?

Thanks a lot!

Hi XXXing,

WRL is the library provided to help write COM component. C++/CX won't help you here.

Sorry, I can not agree with you....

http://www.codeproject.com/Articles/499374/Building-WinRT-components-with-Cplusplus-CX

I believe C++/CX can build WinRT component , the only thing is that all the sample I see is in process component, however I need a out-of-process component, that's the point...

Answer 4

That article is about building Windows Runtime Components (which C++/Cx is designed for), not general purpose COM components (which it is not).

Answer 5

Rob, the OP seems to be referring to an MSDN article which shows how to write an out-of-proc WinRT component using WRL (and an example client C# app that consumes it). It may just be a case of poor article wording there though.

Rob,

This is the article I am referring to :

http://code.msdn.microsoft.com/windowsapps/Creating-a-Windows-Runtime-ed84af9d

It's titled "Creating a Windows Runtime EXE component with C++ sample"

And described as "This sample shows how to create an out-of-process EXE component in Microsoft Visual C++ that's used in C++/CX, JavaScript, and C# client code."

Hi Nishant,

The Creating a Windows Runtime EXE component with C++ sample demonstrates using WRL to create the out-of-proc server component. This is the model that XXXing needs to use, but he is looking for a way to avoid WRL (or defining the COM interfaces without a wrapper).

The article XXXing quotes in this thread is about creating an in-proc Windows Runtime Component. It doesn't use WRL, but isn't relevant to the out-of-proc scenario.

hi Rob,

Do you mean using WRL is the only way to create out-of-proc WinRT component?

My understanding is WRL & C++/CX are tools, the only difference is one work in lower level and another is work in higher, they should archive the same goal...

Answer 9

And I have further question with this sample: Creating a Windows Runtime EXE component with C++ sample

I can download the code and build & run, however, I can not find a project template for this. Which project template should be used for the server project? In another words, How can I build this project from scratch if no project template?

The proxy project seems been generated by code, how to do this?

Answer 10

Hey Rob,

I guess the OP is waiting to get a confirmation for this : "C++/CX cannot be used to create an out of proc component"

And based on your latest response, that seems to be confirmed.

Answer 11

There are no built in templates for WRL projects. There seems to be a client-project template that you can get off the gallery (although I am not sure how up-to-date that is).

Answer 12

WRL and C++/Cx are tools which do different things. C++/Cx doesn't provide any help in defining the interfaces needed for an out-of-proc component. WRL does provide help with that.

Answer 13

Thanks, Rob

So I must use WRL if I need a out-of-proc component.
