This question is regarding dynamic linking of libraries and usage of dynamic linking of libraries in application.

For example we are devloping an application using C++ using Visual studio environment.

Here for include header files we specify in Additional Include Directories, and
in Additional Dependencies: Mylibrary.lib
in Additional Libraries Directories: We specifies path of libraries

And in Windows we also have “LoadLibrary” API which is used to load dynamically linked ibrary.

My question is

  1. when we include dll in Additional dependencies libraries why we should use “LoadLibrary” API?
  2. When we should use “LoadLibrary” API?

Thanks!

    Imagine that you have a software that for example needes at a determined time to convert
    Internet network address into strings.
    On windows vista or later you can use the “InetNtop” function that is also able to deal with ipv6, but if you link directly to the DLL your program will no work on lower OS (ex: windows xp).
    So the best solution would probably be making 2 DLL’s one that used “InetNtop” and another that used for example “inet_ntoa”.
    Then your “main” program would do at runtime a LoadLibrary of the “InetNtop DLL”, or the “inet_ntoa DLL”, according to the OS that he his installed.
