I blogged here http://blogs.msdn.com/sandcastle/archive/2008/01/22/introducing-namespace-diagnostics-and-viewer-for-hxs.aspx about Namespace#, the Diagnostics and Viewer for HxS written by Paul O'Rear, ex-Microsoft Help MVP, is my colleague at Microsoft. You can read about Paul’s work at http://www.helpfulsolutions.com/.
Today we release NameSpace# at http://code.msdn.microsoft.com/NamespaceSharp.
Please note that the current release works only in Windows 2003 Server. An updated version for other Windows OS will be posted soon.Microsoft Namespace# 2.0Microsoft Namespace# 2.0 is a general purpose tool for exploring and experimenting with the Microsoft Help 2.x help system used in such products as Microsoft Visual Studio, Microsoft Developer Network (MSDN) Library, Microsoft Office, and a number of software development kits (SDKs). BackgroundMicrosoft Visual Studio uses a proprietary Help system known as Microsoft Help 2.x; codenamed "Havana". The Microsoft Visual Studio SDK ships a number of components for extending Visual Studio, including its help system. [For more information regarding Visual Studio Extensibility and the Microsoft Help 2.x help system please install the Visual Studio SDK.]Among the components installed with the Visual Studio SDK are a help compiler and a few miscellaneous tools for diagnostic and help content registration purposes. One of these tools is Namespace.exe. Similar to how the concept of namespaces are used in source code for producing application software, the Microsoft Help 2.x subsystem uses the idea of a namespace to define an abstract collection or aggregation of help content.Namespace.exe enables you to perform some rudimentary diagnostics and tasks that are involved with MS Help 2.x help collections and their registration. Namespace.exe was originally developed by the Help 2.x compiler and runtime team at Microsoft. It is useful for a variety of diagnostic information including the following:
Two primary areas to look at are the Namespace and Help View tabs in the UI - these toggle between a diagnostic view of the help system to a more help viewer type mode. The Help view mode is based on the collection you currently have selected in the Namespace mode. There are many features buried in this tool - primary tip is to right click on the tree nodes in the Namespace view to see a number of tasks that you can perform. See screen shot below.
Hope you will like this tool and it's features. Cheers.
