The ATL Registry Component (Registrar)

The ATL 2.x Registrar provides optimized access to the system registry through a custom interface. The Registrar is free-threaded and allows static linking of code for C++ clients.

Note   The ATL 2.x Registrar, provided in atl.dll, does not support Automation or the 1.1 methods that operated on a single key.

This article covers the following topics related to the Registrar:

• Creating Registrar Scripts, which includes:
  • Understanding Backus Nauer Form (BNF) Syntax
    
    
  • Understanding Parse Trees
    
    
  • Registry Scripting Examples
    
    
  • Using Replaceable Parameters (The Registrar's Preprocessor)
    
    
  • Invoking scripts
• Setting Up a Static Link to the Registrar Code (C++ only)

Note   All of the source code for the 2.x Registrar ships with ATL. You can find the source code in atl\src\atliface.h.
