Making an Internet Explorer (IE) Browser Helper Object (BHO) Addon / Extension / Plugin

maximo

Is it possible to use Qt/C++ to make an IE addon / extension / plugin called a Browser Helper Object?

https://en.wikipedia.org/wiki/Browser_Helper_Object

For instance, here's some C++ code, but I don't know if it will compile with Qt?

AFAIK com objects are only available under Windows,
why would you need Qt be involved there?

On the other hand why wouldn't it compile?
Qt even has an addon http://doc.qt.io/qt-5/activeqt-index.html which can make your life easier.

I'll give it a try. I've got a client wanting plugins for FF, Chrome, Safari, and IE. All are somewhat easy (manifest text file + some XML, HTML, Javascript, jQuery) except for IE. On IE, one STILL (yep, disappointing that Microsoft doesn't run with the pack yet) requires that you compile it into a COM object DLL and then through some registry stuff, hook it into IE. (BTW, the new experimental Edge browser from Microsoft has no extension support yet. Windows 10 comes with both Edge and IE11.)
