CShellLink & CUrlShellLink v1.13 2 MFC classes to encapsulate shell shortcuts

These 2 classes encapsulate the IShellLink & IUniformResourceLocator COM interfaces as provided in Win32. These 2 interfaces allow you to programmatically create the ubiquitous shortcuts including shortcuts to Urls.

The class provides an simple MFC wrapper over the SDK API. The class also provides auto cleanup and is UNICODE enabled with build configurations provided.

The enclosed zip file contains the CShellLink & CUrlShellLink source code and also includes a VC 6 workspace file to build a small demonstration app.

V1.13 (20 December 2006)

• Updated copyright details.
• Addition of a SHELLLINK_EXT_CLASS preprocessor macro to allow the class to be more easily added to an extension DLL.
• Optimized CShellLinkInfo constructor
• Optimized CShellLink constructor
• Code now uses newer C++ style casts instead of C style casts.
• Optimized CUrlShellLink constructor
• Updated the sample app to clean compile on VC 2005
