Inlining?

[Tony Vitonis]

From what I can tell, VB.NET doesn't allow programmers to say
explicitly that they want a function to be inlined. Now, I'm a big fan
of factoring out duplicate code, but I don't want to do too much of it
in VB if there's going to be a noticeable performance hit. So:

1. Does the VB compiler sometimes inline simple functions?
2. Is there much of a performance hit on a function call?

Thanks.

I use VB5, so this answer may be open to debate. This is how VB4+5+6 work:[color=blue]

Depends on the compilation options in the project properties. You can change
it to
Fast Code
Does a lot of inlining, especially smaller functions and this may cause a
large EXE file to be produced.
Small Code
This factors the functions, which is the opposite to inlining. It basically
finds similar code and puts them into a function wherever possible to save
space.
No Optimization
Leaves the program exactly how it is. It does no inlining, factorising, or
other manipulation along those lines.
[color=blue]
> 2. Is there much of a performance hit on a function call?[/color]
Depends on the processing power and speed of the program. In a short
program, factorising or inlining will do nothing to the speed of execution.
In a larger or repetitive program, it can change the speed. Factoring
(calling more functions) spends more time pushing and popping the stack and
calling other functions. Inlining (inserting functions in line with the
code) is faster, but it does create more file size.
This is one trade off programmers has to think about when creating a robust,
fast system. I find it better to use my own judgement and use No
Optimization so that I can set how much factoring/inlining occurs.

Hope this helps.

Re: Inlining?

Almost everybody here is using VB6 or lower. While you may get a stray
answer to VB.NET questions here, you should ask them in newsgroups devoted
exclusively to .NET programming. Look for newsgroups with the word "dotnet"
in their name.

For the news.devx.com news server, try these

vb.dotnet.discu ssion
vb.dotnet.techn ical

For the microsoft news server, try these newsgroups...

microsoft.publi c.dotnet.genera l
microsoft.publi c.dotnet.langua ges.vb

There are some others, but these should get you started.

Re: Inlining?

Wow. Only three days monitoring the newsgroup, and I've already found
somebody to put in my kill file.

Best of luck in your VB.NET policing endeavor, Rick. I for one intend
to continue asking such questions, and to continue responding to them
when other people ask them. Bye now. *click*

Re: Inlining?

> Wow. Only three days monitoring the newsgroup

"Wow" is right... I've been volunteering answers on VB newsgroups for more
than 3 years now; I watched Microsoft set up the "dotnet" newsgroups on
their own servers in order to handle the .NET questions directly; I watched
other news servers follow suit and do the same... and in just 3 days,
**you** determined they were wrong to have done so because **you** found at
least a newsgroup with the word "visual" and "basic" in it and you just
**know** that it was meant to service VB.NET questions in addition to those
for which it was originally created. Congratulations on your marvelous
powers of insight; you should apply for a job at Microsoft... they obviously
could use someone as gifted as you to fill in

[color=blue]
> and I've already found somebody to put in my kill file.[/color]

Please do... no VB6 type answer I would give to a VB.NET question you might
ask would be the correct way to code it in VB.NET. Also, kill-filing me
would stop you from continually having to see my standard response to VB.NET
questions posted here in the VB **classic** newsgroups.

[color=blue]
> Best of luck in your VB.NET policing endeavor, Rick.[/color]

I don't need any luck. I post messages here, and in other VB classic
newsgroups confident knowing that Microsoft finds my activities to be
helpful and useful (the MVP designation you see me sign my posts with is a
direct result of having received just such an award by Microsoft; see
http://mvp.support.microsoft.com/ for more details).

[color=blue]
> I for one intend to continue asking such questions[/color]

This is an unmoderated newsgroup, so there is no one who can stop you from
doing so. Strange, though, that you would want to continually parade your
disdain for the rest of the non-dotnet group by doing so. Try logging into
the news.devx.com news server and posting your question on either their
vb.general or vb.getting.star ted newsgroups and watch the moderator of that
group (Phil Weber) move your post to one of the dotnet newsgroups while
advising you that these groups are for VB6 or lower.

[color=blue]
> and to continue responding to them when other people ask them.[/color]

This is fine to do... if someone asks a dotnet question, and you know the
answer, by all means, answer it. The only thing I'd like to see you do then
is suggest they ask additional questions in the newsgroups created specially
to handle questions for the dotnet line of products (which I presume you
monitor also). Unfortunately, you have decided not to do this; so I will
continue posting the message that I did when you first posted your question,
so that these individuals will know of a location better able to handle
their questions.

I'm with Rick on this one. There are much better newsgroups to ask about
..NET topics, hence why I said in my reply "I use VB5", "This is how VB4+5+6
work". It would have been much nicer to just take Rick's reply and just ask
the right people. Talking about a kill file will get people's backs up,
least of all mine. Those who start insulting after being told a small point
like Rick's means they know they're in the wrong.
I, too, have been casually replying to people's questions and comments for
years, and I know that we very rarely get .NET questions, and those we do we
usually send them off to a newsgroup that can reply properly. We do them a
favour instead o them searching for yet more newsgroups. Monitoring this
newsgroup, for however long, will show you how little .NET questions and
answers we actually get, and therefore some kind of bell should have rung in
your head to point you towards the newsgroups with the words "Visual"
"Basic" AND "Net" if you saw them. They have descriptive names for a reason.
I hope you find a newsgroup that can reply to your question, and rest
assured you won't be getting many people asking questions about .NET
products in this newsgroup, which means you don't have to keep monitoring
our group for them, let alone reply to anybody.

Following your logic, I shall start using this NG for asking questions
abut Kylix

I suggest that we all find esoteric subjects that are totally off
topic, and start posting questions on them here.

BTW if Rick did not politely point dot.netters in the right direction,
then others of us would ask them to bog off
- far less politely

[Tony Vitonis]

Re: Inlining?

You're free to ask whatever questions you like, of course. As am I.
And if I'm told to bog off, then I'll just add another entry to my
kill file. Couldn't be simpler.

Have a nice day! =c)

Re: Inlining?

As I said, I intend to keep asking questions wherever there's a chance
that I'll get a good reply. I think it's a perfectly good practice,
and I'll killfile anyone who tries to berate me for it (Rick, e.g.) --
not because I "know I'm in the wrong", but because I won't have my
news data cluttered with vitriol from insecure small-minded children.

Thanks for your suggestions, though.

add me too; it won't be long before you are alone here and maybe then you'll
just find it easier to go to the right place rather than continuing to
bother people with off-topic posts.

I'd like to be in your killfile too; in fact, I think all classic VB
posters should likewise volunteer...

Looks like you're going to have a pretty big kill file

[Tony Vitonis]

Re: Inlining?

My question was about the Visual Basic language, posted to a group
called comp.lang.visua l.basic. Your replies are the the bothersome
off-topic ones, though I understand that I'm contributing to that
here.

By the way, I'll add whom I like to my kill file. Thanks for the many
suggestions, though.

Have a nice day! =c)

He won't listen Bob... I tried patiently explaining that to him and, for my
efforts, he kill-filed me for "berating" him (his term, not mine). You
really gotta marvel over the arrogance of personalities like Tony. I wonder
if, when approaching a public rest room (loo?) with the words MEN and WOMEN
on the door, whether Tony feels free to enter either one since he sees the
word "MEN" on both doors.<g>
