reverse engineering - Difference between bound imports and delayed imports in PE header -

-

could 1 please explain differences between bound imports , delayed imports in pe header.i have referred few books cannot understand concept of clearly.can me out.

bound imports means in pe-import table store fixed (bounded) addresses of import functions specific version of dll function. bounded addresses calculated , written import table linker during program compilation , linking phase.

delayed imports means in import table instead of import functions addresses contains addresses of special program part called "delay load helper" (sometimes called "thunk"), substitutes real imported function address when function called first time. , subsequent function calls use real function address written delay load helper.

it concept. details can find in iczelion's pe tutorial, example
