Using C++ with the Win32 API, is it possible to design a feature-rich and interactive HTML rendering window that will allow your application to receive callbacks from

What my team needs is straightforward: we are working on a console app project and we require a function that opens a basic window displaying only HTML (default system-based) with JavaScript rendering. This window should read a default HTML+JS string (either from a string or const char*). We aim to integrate our own API with the default JS API so that when JS calls our.function(argument);, our C++ application can execute a function like couting the argument value. How can we implement this on Windows?

Answer №1

Initialize the MSHTML com object for rendering HTML Documents:

Create a CComPtr named spDoc; Examine the HRESULT from CoCreateInstance(CLSID_HTMLDocument, NULL, CLSCTX_INPROC_SERVER, IID_IHTMLDocument2, (void**)&spDoc);
Refer to a resource like this link to parse your HTML string and display it on the document.
To interact with the HTML DOM tree and receive callbacks, utilize the COM DOM Interfaces and event sinks provided by DispInterfaces. This approach is recommended.
If the suggestion in step #3 does not meet your requirements, you can develop your own ActiveX control and allow scripts on your webpage to invoke its methods as per raj's recommendation.

Answer №2

Disregarding any worries about security or compatibility issues, you have the option to incorporate an ActiveX object in your C++ code that can be called from JavaScript.

Answer №3

When using the WebBrowser control, the host has the ability to provide an object that can be accessed by scripts through the external object.
