Subject: OT why should i study vc++

hi all
well i am student and i have been continously been told to study vc++ by
friends ,... but non of my friends can explain to me why should i learn it ,
could you please let me know...
1. what is vc++ ??
Think you've gotten the answers to this one already.

2. why should i learn vc++ though vb is there and
   supposed to be much easier thatn vc++

VB is good for simple tasks, of which there isn't really many. If you need
to write a quick program that imports something into a database, VB is
great. UI is good, but definately has its shortfalls once you try writing a
full application that looks like many of the current microsoft products.
Also VB's unicode support is ok, but not great. Once you get out of the
league of simple things, you find yourself doing so many kludges to get
things to work the way you want, C++ would have been equal or faster, with
less kludges to begin with. For example, I was using the Microsoft Winsock
control to transfer data in VB, everything was working, and all the sudden
it stopped retreiving data. Now I go on the newsgroups and find that this
happens occasionally, well, thats too often for most apps, so I have to
breakout to VC++ and write myself a COM control in ATL that does what I
need. If you ever need to subclass a window in VB, you will find that often
you will spend more times restarting VB then actually debugging your code,
whereas VC++ you can subclass a window (which is something you have to do
fairly often) with no problems. In VC++ you can create Free Threaded COM
components, which are considerably faster and easier to work with (IMO, alot
less marshalling). VB's has unicode support, but most of VB's controls
(buttons, forms, etc) are not unicode compliant, so unless your calling the
API's directly (in which case, why use VB) you cant get unicode support.

That said, VB does have its advantages. One thing I hate in C++ is dealing
with error handling, it seems like after every call that I have to check and
possibly handle an error, I think my code consists of mostly error handling
code. VB's error handling is a little easier and cleaner. VC++ has
exceptions too, but often you will have a function that you expose that cant
throw an error, because you cant throw errors across com, so you have to
return an HRESULT, so you have to check that every time.

3. what is the plus point with vc++ which is there in
   vb and other windows based languge.

I think I went over those above, plus VC++ abilty to do services, etc.

4. what new things can i do in vc++
5. how usefull it is in .NET technology.

thanx alot if any of you could answer these question.,
