/DELAYLOAD (Delay Load Import)
The /DELAYLOAD option causes the DLL that's specified by dllname to be loaded only on the first call by the program to a function in that DLL. For more information, see Linker Support for Delay-Loaded DLLs. You can use this option as many times as necessary to specify as many DLLs as you choose. You must use Delayimp.lib when you link your program, or you can implement your own delay-load helper function.
The /DELAY option specifies binding and loading options for each delay-loaded DLL.
