Implement DLL Functions

  • Artículo

A plug-in that extends the Windows Vista photo acquisition experience must be a DLL that implements the following functions, so it can be registered, unregistered, and loaded into memory.

  • DllMain The DLL entry point. Your implementation may wish to save the hInstance parameter in order to get a module path for use in the implementation of DllRegisterServer.
  • DllGetClassObject Creates a class factory instance, using your implementation of IClassFactory.
  • DllCanUnloadNow Queries whether the DLL can safely be unloaded.
  • DllRegisterServer Creates registry entries for the DLL. The required registry entries are described in Register the Plug-in.
  • DllUnregisterServer Removes registry entries for the DLL.
