>many vfp experts told me vb is only a object-base language but i found a book what it said vb is oop. i am trying to learn vb. when i open the vb program, its seems no difference from oop.

Who's the name and author of that book?

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. :)
