Begin Rant

Don't be surprised by VB, it's a very powerful language and in some cases
faster than C++. If someone is telling you that VB is always slower than
C++, they are full of it!  This perception of VB as a slower language is old
thinking. There is still a lot of resistance to VB from the C++ community (I
was one of those guys a few years ago).  Do some benchmarks for yourself and
see what the actual difference is.

I don't want to get into the "good" VB code outperforms "bad" C++ code
debate, but VB is a totally legitimate and powerful development tool that is
often ignored by C++ developers.

                Well if VB is fast I would recommend you to go with VB.

                In fact I am myself amazed with something that are very fast
in VB compared
                to C++.

                One of the things is iostream vs
"Scripting.FileSystemObject"

                iostreams (atleast VC++ implementation) perform very badly
in comparison to
                Scripting.FileSystemObject. (This even includes the
conversion from ansi to
                UNICODE which FileSystem Object does).
