hi there,

i know that everyone says that C++ is a more low-level language for
programming and all...what is the real performance difference between using
VB.NET, C#, and VC to create a windowsform application using .NET?

is there some website with more information on this kind of topic?

thanks,
Paul.
 
im not too fussed.. its only a dud email i use which collects spam mainly.
Anyway, i dont know how to remove it. im using outlook express and the
settings require an email address???

thanks,
Paul.
 
Hi Paul,

First of all - pls make sure to remove your email address while posting in
the public newsgroups - otherwise you'll start to recive more and more SPAM
every single day :)

About your question:
The only difference is in that with C++, you can mix managed and unmanaged
code in one place.
Otherwise, if you're just using the framework, you'll get the same
performance - that's caused by the fact that the final optimizations are
being made by the JIT compiler.

For more info on VC++ .NET and .NET:
http://msdn.microsoft.com/visualc/productinfo/faq/default.aspx

Here are some links on the performance tweaking and best practices in the
MSDN:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/optimaldotnet.asp
http://msdn.microsoft.com/library/en-us/dndotnet/html/highperfmanagedapps.asp

About the difference between VB and C# -
there are a couple of things you should consider while you choose between
them:
- VB comes with additional library (Microsoft.VisualBasil ...) - all of
the old funcitons that VB devs have used to - before .NET
- C# is more powefull in terms of things you can do - for example
operator overloading is not available in VB.
- becouse of that additional library I mentioned before- there are some
nasty funcitons/operators that can cause you troubles in some situations -
like the redim operator.

So my best advice for you - use C# while writing .NET apps and C++ only when
you really need it.

Cheers,
Branimir

There's no need to do that. It's a personal choice. I would rather make
it easy for people to contact me and fight the spam myself - given that
my email address is available on my website *anyway*, it makes no odds
to me whether or not it's also available through news. Perhaps Paul
feels the same way...

I certainly do. I find it more annoying that my email messages bounce
because I forgot to decrypt the target address than getting spam mail.
Besides, hotmail seems to have improved their spam fighting and antivirus
tactics as I get far less of those now, and I have used this address in
several news groups in well over a year.

The common thing to do is either "despam" it, so that you give it an
address like:

(e-mail address removed)

so that a human can (in theory) work out what the address is, or give a
completely bogus address ([email protected]).
 
Jon,

You are right, it is a personal choice, but I can attest that while for
the longest time, my email address has been on my website
(www.caspershouse.com), it wasn't until I placed my real email address in
newsgroups that I started to get copious amounts of spam.

I can attest to the fact that these newsgroups are culled regularly for
email addresses. As a result of placing my correct email address in the
newsgroups for years, I now get on average 150 pieces of spam mail a day. I
would change my address, but I am partial to the address that I have, and
reluctant to change it (a personal choice, I know).

Additionally, someone has even spoofed my domain in their spam, so I get
all sorts of no-delivery notifications from domains where the email address
that the spam was being sent to doesn't exist.

Because of this, I now do what you had pointed out, create a fake email
address that a human reading it could interpret correctly (at least most of
them) and will fail if a machine parses it and doesn't know which parts are
legitimate and which are not. I can't say that it has reduced my spam
intake (and it's only destined to get worse over time), but I believe it has
curbed the increase in the number of pieces I get per day.

Just thought I would throw my $0.02 in.
 
I agree that's a personal choice -
however I decided to give the warning - my old email at the company I used
to work for still recieves about 250 messages a day. The filters are getting
better, but they still can't cleat all of crap that comes in. Besides
there's a pretty good chance to overlook an email just becouse you thought
it was SPAM.

Cheers,
Br.
