Thank you.
WTL wraps Windows API functions and messages into C++ classes. Like many QM functions do. As well as like MFC, .NET and many other libraries do. Of course if you have WTL source code, you can see what API functions and messages they use to implement something. I sometimes look at MFC source code to discover what API to use or how. But WTL (and most other libraries) don't have anything that you could not do by calling Windows API directly. All these libraries just make programming easier.
