Where is that, the Introduction to OLE?
It was part of the MSDN Library or available as a book. Dunno where it got to. (Check msdn.microsoft.com)
I think the book you guys are talking about is "Inside OLE", Microsoft Press, by Kraig Brockschmidt. Available for free in CD version of MSDN, not sure about online. Other books to check out are "Inside COM" from MS Press (not sure the author), and "Programming Applications for Windows" by Richter goes into some of the messy stuff involving thread, processes, etc..
