So far, all xpcom examples I saw are Firefox addons. You write some C++ code, build, and register it. This resembles Microsoft COM in-process server, but instead of Windows registry the component information is stored in Firefox profile.
Does Firefox have out-of-the box ability to control it from another process using same API? Somthing like COM's local server application
When you start a second firefox instance, it communicates with the existing firefox process and tells it to open a new window, then dies. I suspect it uses some remote form of xpcom.

I need advice about the best way to make an application (written in c++/mfc) communicate with an extension in chrome (I am also studying edge chromium)
As far as I understand, the native application that the extension can communicate with by using native host messaging is launched by chrome. As my win32 application is launched by the user and not by chrome, I need the native application to be a third component, launched by chrome.
What is the best way to let my win32 application communicate with my native app ? Making it a COM server is a good idea ?
I have searched on the other posts but they often talk about the native app talking to another app, not the other way.
Thank you
I'm trying to automate a desktop application but I can't inspect its elements using tools such as Spy++, Inspect.exe, UI Verify... The application is old aparently built with C++.
Is there anything I can do?
I've thought about reproducing the application communication with the server via code, but I wasn't able to identify HTTP requests/responses between them.

I would like to access Bluetooth LE devices using the corresponding UWP APIs. However, my application is a "classic" C++ application (3D game) that can't run as a UWP app. Is there a way to do that? Accorind to enter link description here these APIs are published, but I don't know the steps to access them I have only found some posts for Windows 8/8.1 apps that include the Windows.winmd and Platform.winmd metadata files and set the /ZW compilation flag, but this doesn't seem to apply to Windows 10.
You should be able to do this, as the Bluetooth classes (e.g., BluetoothLEAdvertisement) are marked up with DualApiPartitionAttribute (callable from desktop and UWP apps).
Using one of the older Win8.1 desktop samples should give you a good starting point for calling the APIs without requiring /ZW or referencing the winmd files. A good example is the desktop toast API sample.
If you go that route, you can use classic COM to create the UWP/WinRT classes via WRL helpers.
You can use the web that you make a web server and the C++ application use the same server and if UWP send the info to server then it will send the info to C++ application.
To safe,the UWP can't use the desktop app.
my question might be crazy, I know it has to be something like COM, but I need to include and COM a specific version of Web browser in my application no matter what version of the browser the computer currently is using, say to include IE7(dll file or whatever) in the project and COM programming it as a window in C++ application to surf web pages on internet although the default browser in client machine is IE9. And deploy the compiled project with IE7 file(s) to client machines. If IE/COM won't work that way, any other browsers can do the tricks?
Many Thanks!

No, you cannot "embed" a specific version of Internet Explorer in your application. But you probably don't need to: when you use the IE COM WebBrowser Control in your application, by default it runs in IE7 Compatibility mode. Later modes are only used if you explicitly set the FEATURE_BROWSER_EMULATION registry key listing your executable name.
I am having a desktop application which having a UI interface made in Qt linked with a library which is doing all the calculation stuff. Values from UI is taken and pass to the API's in the DLL to get the output which is shown on Screen.
Now i want to do the same thing by transferring my application UI to a web page so that people can access the tool from anywhere without any installation process.
I want to retain my c++ DLL code so i don't have to do a lot of work. I am thinking of just converting this DLL to a C++ server by any communication Process(Sockets). I want to host this application on my company's website. (We have to make the website also so we are open to any set of tools).
I want to know what will be the best set of tools to do this stuff. Also there will be lot of data exchange between the webpage and server so the wholething should be optimized also. I goggled a bit and find stuff like silverlight and ASP.NET, But i am still not very clear which option will be more suitable.
I am a c++ programmer with no web application development experience. I am open to learn any new technology.
Thanks
Why not use Qt on the web directly? There are several projects like this one: http://qtwui.sourceforge.net/
There is a netscape plugin that will host a QT application and an ActiveX control wrapper on the QT website. You could use one of those to wrap your application. Note that this approach would require the user (or their administrator) to download and install the plugin.
An alternative approach might be to run your application through a remote desktop such as XVNC, NX or an RDP based layer. IIRC browser based remote desktop clients are available for most such protocols.
A few options:
pick a messaging/queue implementation (like http://www.zeromq.org/) and provide a service
implement a Windows Web Service if you want to be more enterprise friendly: http://msdn.microsoft.com/en-us/magazine/ee335693.aspx
I would not expose the implementation on the internet. Enough to have a simple buffer overflow and the machine can be taken over quickly. Adding a layer between the app and the web provides an easy way to validate input, access, stats ...
You should be able to use your DLL from an wt or cppcms application. Then you do not have to learn something new and can just use C++.
The way I'm currently doing this is with Boost.Python + django
