App Eficiency ?

... just a follow up,
I created a small VB6 app, and it takes 2% of
my processing resources.

Now... both (VC++6 & VB6) apps just sit there and do zippo,
why, or what tecnique does vb6 use to make its apps
so eficient? so processor in-intensive?

This questions is up...

Obviously your main loop will be the one taking up most processing power... it''s only natural. It''s getting called several times per second (you should hope). I wouldn''t worry about for now. You probably won''t have too many problems. Most gamers don''t run background programs while running full-screen games anyway. Either way, you should probably be okay.

Okay a couple of ideas.

1. What 9x are you using? some are notoriuosly resource intensice
2. VB uses very little resources because it doesn''t do much anyway

...what about the vb6 app?
what she doing thats so wright?

my system is a dual P3 1Ghz each
with 1gb ram running W2K.

Lamers saying I''m lying will be shot on site!

no other apps, except windows background stuff is running...

VB is very resource efficient where as C/C++ couldn''t care less (i.e. you need to do it all).

Any resource initialised in C/C++ needs to be ''DeleteObject''ed where as in VB when the resource is out of scope it is deleted automatically.

just my 2 cents.

THAT makes sense... !!

Yeah... just make sure you are freeing any resources used by your program eventually. You should be fine.

If I knew what vb does to eliminate excess processing...

Yeah, VB6 is much more efficient and less resource intensive than C++. That''s why all the good games were written in Visual Basic and why all the lame games were written in the slower and extremely bloated language known as C++.

P.S. What does your main loop do? Is it the main wndproc loop processing windows messages, or is it something like:

for(;
{
// do something here until I''m done doing something here
}

If the latter, therein lies the problem.

No, C++ is generally faster than Visual Basic.

pentium3:how''s your main loop organized?
if it uses PeekMessage then it is looping in a loop which does nothing.(actually a new frame should be drawn - if it''s a game - every time you check peekmessage) And it should actually take 100% of your cpu time (maybe 50% because you have got a dual system and it simple is too small to be executed by the second cpu)
if you have got a small app which DOESN''T need to work all the time (ie it should only work while some messages come in like mousemove etc.) you should use GetMessage!!!
I would guess that''s your problem. Another idea might be that you have made somewhere a big big stupidity in your code

hope it helps
ps.if you''re using PeekMessage read somewhere about it and GetMessage to get the idea what''s the difference and how it works.

C++ is not resource intensive. It is platform independent. VB hides and ENORMOUS amount of complexity. i.e. instantiate a bitmap and it doesn''t get loaded until it ges used, i.e. dom''t use it, it don''t get loaded.

I''ve used C++ on 3 platforms (C on 5), i''ve only ever used VB on one (VBScript on 2). Each operating system presents its own chalenges when it comes to resource/memory usage.

as allways, gamedev posters are thA Best!
u guys r right! its tha peekmessage thingy!

// enter main event loop while(TRUE) { if (PeekMessage(&msg,NULL,0,0,PM_REMOVE)) { // test if this is a quit if (msg.message == WM_QUIT) break; // translate any accelerator messages TranslateMessage(&msg); // send the message to the window proc DispatchMessage(&msg); } // main game processing goes here } return(msg.wParam); }

btw, how do u guys do that white board thing. I see it often, when ppl post code...

Look at the faq. Just type the word source with brackets surrounding it and /source to end it. Like this without spaces: [ source ]
...
[ /source ]

You know what. I''m reading through some of my old posts. I figured the extreme sarcasm from my last post would have shown through. Of course C++ is better for writing games. I don''t actually believe any of what I wrote (since I was being sarcastic to prove a point...which didn''t work obviouslu)

It ought to take 100%. If it''s less than that the program is calling Sleep or a blocking function somewhere (both of which needlessly reduce performance in a full-screen game - when called in the main game loop).

He said is computer is a dual proc machine. The app is probably single threaded, and running only on one proc, hence the 50% usage.

I missed that ^
Show one graph per CPU

You''re using PeekMessage where you ought to be using GetMessage if you don''t what your message pump to run flat-out.
