Firstly, you should tell us more detail about what you want?
If you need the functions list of these DLL, you can find it in the link that the other one give here. But it is good for you if you are Visual Basic programmer.
If you are newbie, you should find the some books about Microsoft Windows Programming by C/C++. There are two kind: MFC or Win32 APIs. I think you should learn about Win32 APIs, you can use its knowledge for any MS Platform.
