Thanks Edward and Micheal.
The book's name is "Using Visual Basic 4" by Que. In the first half of the book, he hasn't said VB is oop but in some sentence, such as p.441 "Visual Basic's new object-oriented language features change the way..." and same page "This chapter introduces you to object-oriented programming with Visual Basic and readies ..". Perhaps, my English is too poor. Its makes me very confuse. But, before I received your messages, I just found in p.449, he said "Visual Basic is not yet fully object-oriented". After I read your messages, I really understand VB (but not programming).

>>I also have heard this many times and it's still true today that VB is object based and not object orientation. That might be the confusion. However, I am not a VB user so I can't tell. But, I'm sure this is gonna be a long thread. :)
