Linker > InputAdditional Dependencies, add library: delayimp.lib;Delay Loaded DLLs, add all the DLLs you want to delay load.rapi.dll;ceutil.dll. If you forget this, and try something like: rapi.dll ceutil.dll, then the linker will treat the whole string as the file name of a single file and fail to find a file with that name. There will be a subtle warning during build: LINK : warning LNK4199: /DELAYLOAD:rapi.dll ceutil.dll ignored; no imports found from rapi.dll ceutil.dll, which most likely will be ignored.__HrLoadAllImportsForDll is the recommended function by MSDN documentation to do the job.__HrLoadAllImportsForDll because it use memcmp to compare DLL file names byte by byte which is too strict. File names in Windows system is not case sensitive, so the file names can be the same even if memcmp fails. This function will return module not found error code even when the DLL files are installed on host computer. I end up lift the implementation from delayhlp.cpp, and replace memcmp with _tcsicoll which is case insensitive.
