I'm using C++ Builder in my day job and the documentation is sparse, with very few examples and most recent books are from the early 2000's.
Microsoft still hasn't managed to offer anything similar for C++ (other than the shortly lived C++/CX) in 25 years.
Although I do agree the documentation is awful, specially when compared with the old Borland printed manuals.
