What are the different ways with which we can dynamically Link a DLL

I want to link a .dll dynamically. What are the multiple ways to do so?

One way I know, is by using HMODULE WINAPI LoadLibrary(_In_ LPCTSTR lpFileName) function. Is there any other way? I am trying to understand the below code:

#if defined WIN32
    // We want to define DTE_DLL_EXPORT if we are making
    // a dll, but not if we are making a static library...
    #if defined DTE_STATIC
        #define GFITDTE_ENTRYPT
    #else
        #if defined _GFITDTE_BUILD_
            #define GFITDTE_ENTRYPT __declspec(dllexport)
        #else
            #if defined DTE_IMPORT
                #define GFITDTE_ENTRYPT __declspec(dllimport)
            #else
                #define GFITDTE_ENTRYPT
            #endif
        #endif
    #endif
#else // Not WIN32

Can some on explain the above code??

The code shown has nothing to do with LoadLibrary. It's typical for header files, which in turn means you're building a DLL that's NOT supposed to be loaded via LoadLibrary. Instead, the compiler knows the function prototypes from the header, and the linker uses an import library to set up the DLL linking.
