There's Get­Class­Name and then there's Real­Get­Window­Class. What makes Real­Get­Window­Class more real? Recall from last time that the Real... functions were added to support Windows accessibility. The goal with Real­Get­Window­Class is to help accessibility tools identify what kind of window ...

WindowFromPoint, ChildWindowFromPoint, RealChildWindowFromPoint, when will it all end?
