i ran into a web site

http://theopensourcery.com/vbover.htm

which states that VBA is facing a slow & painful death. :0
granted, the info seems to be <2005, so here it is 2 years later & VBA
is still here. but people on the NG seem to be having a lot of
trouble with excel 2007, so........

VBA is a program-based programming language. i see (on the net) that
C# & C++ are Windows-based programming languages. can they be used to
do the same sort of stuff we use VBA for??? if not, what types of
things (in general) do you use it for?

what is the difference between VB & VBA (& VB.net)? can VB & VB.net
also be used to manipulate programs (like VBA)?

i am loving learning VBA but if it's ultimately going to die out then
perhaps i should focus my head-banging toward some other language with
more longevity?

what do you guys think? i see that most of you also have additional
programming skills other than VBA so i would greatly appreciate your
opinions.
thanks!
