Asp+| program finally have time to learn something new, today, a cursory look at the information about asp+, and wrote a domain name Query page, feeling very good, asp+ than
ASP to progress is too big, although using asp+ components can also realize the function of domain name query, and a few days ago I used VC wrote such a component, but with asp+ simple
It's much more convenient. Okay, cut the crap, look at the source.
