Microsoft Interactive Developer published a piece devoted to some shell extensions for Dynamic HTML files in the February 98 issue. In particular, the article shows how to extract some content information from an HTML file. The approach is different from the one discussed here. In fact, the language used is C++, and there's no utility to build but a namespace extension. However, many of the accessory topics covered there are useful to enhance this DHTML X-Ray tool, too. The first example that comes to mind is extracting the DLL file name from a CLSID. The article is published in the Cutting Edge column.
To learn more about the Win32 executable file format, you might want to check out the Under The Hood column in Microsoft System Journal, run by Matt Pietrek. It's likely that there you find just the tool you need. In particular, we recommend you read the February 97 issue.
