well it madders what you going to make.c++ is more like java then anything VB is more used and power shell is like windows 95 and it was made for  makeing admins
but when you want to make like a chat spammer it better in VB then c++.
dont get me wrong c++ is good too but good for like programing games and hosting program, and VB is used to make all the starcraft bots.so i would learn VB first then c++
and power shell is good for like account making like my chat room(that died and i had to take down) uses power shell for like login and i use VB for chat and c++ for the hosting with lixux
