word docs? How to manipulate in C#?

Hello all, new to the forums here.... I am beginning my first major project creating software that in part must deal with importing information from .doc files, and possibly export information to .doc files. I know nothing about this, and I'm wondering where to start as far as learning the in's and out's of manipulating .doc files from c# The software is for creating, proctoring, and taking exams, and some things it must do are: *be able to import a word document that may contain images *be able to parse a word document for test questions it contains *be able to export a graph of the test results to a word document *stuff I haven't thought of yet... Could anyone point me in the right direction as far as articles, books, even just the classes I might use for manipulating .doc files??? Thanks! Arian Goodwin
