Once again you seem to be unwilling to do your own homework about things you should
search for before
asking basic questions. Did you try something, such as "ForwarderChain + IMAGE_IMPORT_DESCRIPTOR + PE" (without the quotes) or even "ForwarderChain + PE" (again with no quotes) in your favorite search engine or is this the first place you post every time there is some programming information you do not already know?
Get off your lazy butt and do some of your own searching FIRST.
The point here is that just because you haven't read anything about the subject
yet, doesn't excuse your failure to search for the information
BEFORE you post here asking someone to do this minimal effort for you.
