How do you get a specific Interface...

I have:

CLSIDFromProgID(OLESTR("BackWeb"),&CLSID_BackWeb);
Hr = CoCreateInstance(CLSID_BackWeb,NULL,CLSCTX_SERVER,IID_IDispatch,(void**)&pDisp);

I have tried:
IBackWeb* pIBackWeb;
pDisp->QueryInterface(IID_IBackWeb, (void **)&pIBackWeb);

The compiler complains that 'IBackWeb' : missing storage-class or type specifiers
and
'IID_IBackWeb' : undeclared identifier

Is there a way to get the IID for IID_IBackWeb?

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.

Web Components are a set of standards currently being produced by Google engineers as a W3C specification that allow for the creation of reusable widgets or components in web documents and web applications. The intention behind them is to bring component-based software engineering to the World Wide Web. The components model allows for encapsulation and interoperability of individual HTML elements. Support for Web Components is present in Chrome and Opera and is in Firefox (with a manual configuration change). Microsoft's Internet Explorer has not implemented any Web Components specifications yet. Web Components consist of 4 main elements: Custom Elements, Shadow DOM, HTML Imports and HTML Templates.

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
