Why we obtain HMODULE for kernel32 this way:

  

     // get handle to kernel32

     if (GetModuleHandleExW((GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS |

                            
GET_MODULE_HANDLE_EX_FLAG_UNCHANGED_REFCOUNT),

                            (LPCWSTR)&CreateFileW, &h) != 0)

     {

         ...

  

  

instead of

  

     handle = GetModuleHandle("kernel32");


GetModuleHandleExW allows you to provide the address of a function in
the library that you need the handle for and so you avoid issues when
multiple libraries with the same name are loaded.



:

  

Also according to MSDN GetModuleHandleEx requires at minimum "Windows
XP" or "Windows Server 2003". It means that we do not support "Windows
2000", right?


I don't think it's been possible to install or run jdk7 on Windows 2000
for some time.
