You need to have a copy of any edition of Matthew Curland's Advanced Visual Basic 6 to use this site. All the material here relates directly to the book.
Note for readers of the Chinese edition: I don't have a Chinese version of the book, and I lost the login information with the last PowerVB server. I'm searching for the information and will enter it when I find it. In the meantime, please send e-mail to get the files.
