Be advised that from VB to C++ is a pretty long journey:
Pointers, objects, files to include, libraries to link with, etc. may be tricky.
A good link:
http://www.cplusplus.com/Using a GUI (not just console output) needs also understanting what a message-driven application is.
Perhaps you need to know C:B is not a compiler, but an IDE.
Depending on from where you have downloaded it, a compiler for MSWindows (MinGW) is also provided wit C:B.
C:B let's you choose the compiler you like.
In order to do your first steps, start a new Project in C:B, set its properties (i.e. Build target type: GUI or Console app) and add a new .cpp file to it.
Good luck!
