  • Embed an HTML control in your own window using plain C
    Specifically shows how to embed a browser OLE object in your own window, and more generally demonstrates how to manipulate and create COM/OLE objects, in plain C (ie, no MFC, WTL, ATL, .NET, C#, nor even C++). The latter is applicable to many other uses, such as creating your own script engine.
