How to develop an IE plugin that will execute within browser with <OBJECT> tags

I'm new to the realm of web/plugin development and I'm not sure what I need to be researching.

What I need is to develop a C++ app/dll/control/something that will install as a browser plugin and can be embedded and ran within IE when <object>...</object> tags call it (or any HTML tag that will embed something of the sort). Exactly how Adobe Flash executes within a given space within an IE window.

I've searched and have seen and开发者_Python百科 created a basic BHO, but that doesn't seem to be the functionality I need, or maybe I haven't looked deep enough into its abilities.

Any tips or pointers?

I think you're looking to develop an ActiveX control here

Using ActiveX Controls to Automate Your Web Pages

The term for browser plugins used by Microsoft is Content Extensions. They are ActiveX based and allow you to add alternative content to a web-page as well as scriptable interfaces.

If there is a possibility that you'll need to support more than IE, consider using a wrapper like FireBreath that allows you to support multiple browsers from one code-base.
