Btw you are not a professional either. so stop saying you are. I can tell by your coding mistakes. GetTickcount Can't be long. It will append zeros in the bits and turn the number very wrong. try maximizing your form and reading the time. it will be like 4444411232 , but I fixed that for you

i have ran both of the apps and joeman is right and i think he is being pretty
nice about it because i would grab you by your nuts and show you no mercy

.Net scored 3500ms Vb6 scored 100ms
vb6 wins
if you dont believe me i will video tape it
i don't believe pls video tape LOL
... and some think vb6 will die soon? even KKK didn't have so "warmed-up fans"... VB6 will live for at least as long as VBA and VB Script will be out there, somewhere...
K now, after the introduction, my real comment about these tests: they do not prove anything real to anyone... especially when the test involves graphics... do you guys know that hardware is more often the cause for bottlenecks than software? as well suited is a software for the hardware on which is running... as fast it wil be! take for example 64 bit compiled code running on a 32-bit machine through WOW... most probably would be slower than 32 bit software on the same machine; try running CE software on a desktop (using a PDA image)... even that the desktop processor is faster, the same software would execute faster on a PDA with slower processor; Intel compiler optimizes better for Intel processors; applications using OpenGL will draw faster on graphics cards with better OpenGL support; numbers (X ms versus Y ms) are meaningless without environment specs... and so on...
Conclusion: dedicated software is usually running faster; languages are NOT making applications faster or not, DEVELOPERS are responsible for that, and can have the help of compilers (and other dev tools)
Uf... can someone please CLOSE this thread?
And I also belive that I was the one that pointed out that some of the equvalent functions can and do have different results.. CPU Wizard pointed out the .NET manages the code and has built in checks for invalid information..

.. Sorry to say, but i do belive that i'm a hell of a lot more professional than you could ever dream of becoming..
Professionals are human and do make mistakes, and the SINGLE mistake you claim that i've made was on something that i made no claim to be 100% anyway, It was code that i quickly did between working fulltime as a professional developer, writing articles for codeguru, Helping out other CG members, and SLEEP... Between all that i also try to spend time with my wife and my grandkids...
I also have hundreds of applications written years ago still running in there respective area's, I have put some of my Personal projects up as Open source software.. FREE for all to use as they see fit.. One has already hit the 2000 downloads mark here on CG alone.
My professional programming ability has been demonstrated. Yours has not.

Reason: fixed Html tags
About test1... It does work, but it only does tiling. It doesn't prove anything unless your going to keep the app tiling. In that case, it would be faster. Also, you can't use test1 for anything else, but for tiling. You can't use it to make a simple game. Also, test3 may have been faster, but it is still alot slower than the vb6 version. Did you look at the difference? Download the attachment I just did and rerun them at full screen.
If you code professionally, I am amazed. Seriously.
Why is your test still tiling lines for? That wasn't the real test. The real test was with a music treble clef sign. ....
Also I didn't see your vb6 code for tiling of the line. I am sure you made mistakes. Can you redirect it to me?
All the links are in my previous post.
And unles someone can come up with a different test, other than graphics, I think it's time this thread dies.

If all three tests done gave the same result i'd say fine. However to completely ignore the last two tests because the results are not what you want, and focus on only the slowest .NET code and say 'There you see .NET is 1000 times slower' is not right...
Have a look at the .NET code Hannes posted for test 1, it performed so well that i had to escalate it up and divide the time to get a true result...

Put up or back out.. Lets the rest of us see what you've done..
I think we can agree straight apis are faster than managed .net apis, but We should come up with a better test. I just don't know what since I keep thinking simple = something visual.
Btw, most of my code is probably against some rule on the aup or in c++

I won't tell you what it does or how to use it, but it is an ongoing project. I am building this not to reinvent the wheel, but learn how to build that wheel
I told you I am no pro, but I don't think I am a mere newbie.
OK, this should be the final speed test, unless the results call for more.
This time there's no graphics, just pure math, in a loop. Also a CheckBox to allow selecting one of two different algorithms. Just as with the others, the TextBox determines the number of times through, and the time is shown in the TitleBar.
Please remember to rate the posts and threads that you find useful.
How can something be both new and improved at the same time?
I should also point out, that the latest round of offending posts have not gone unnoticed. Those of you able to maintain your professionalism can give yourselves a pat on the back. The rest of you should feel free to slap yourselves silly, and may the fleas of a thousand camels infest your armpits
Please remember to rate the posts and threads that you find useful.
How can something be both new and improved at the same time?
Might I also suggest something more complex, and look at performance for recursive algorithms? I know this allows for some variations in language use,but I still think that, as we've left graphics, it would be a useful comparison. A good algorithm might be the one at http://www.codeguru.com/forum/showthread.php?t=457281, although this would need rewriting in VB.NET, and my VB6 version could do with some clearing up...
This, however, may not show much speed until quite a large dataset is used...suggestions?

VB.NET code is made up on the spot with VS2008 Professional with .NET 3.5. Everything else is just made up on the spot.
Please Remember to rate posts, use code tags, send me money and all the other things listed in the "Before you post" posts.
I was also thinking of something along the lines of string sorting, like the dreadfully slow BubbleSort algo. It's simple enough to translate to .net without much fuss I'd think.

Yeah we need a good example to start off with. Simple recursive stuff isn't going to state much, but actually if you compare vb6 and vb.net to c++, you will find even the smallest stuff can show you how fast c++ is. Well I was bored and I decided to convert wizbang's code to c++. Although I didn't use the gui, I only used the console, I think it came out as a nice conversion.
Here is the c++ conversion. Now we need the .net conversion. After that. We will do something else.
Code:
#include <iostream>
#include <windows.h>
#include <math.h>
using namespace std;
int main()
{
int I(0), J(0), K(0), T(0);
int Method(0);
SYSTEMTIME Time;
cout << "Please input the number of times to process: ";
cin >> J;
cout << endl;
cout << "Please select what method of process you want:" << endl;
cout << "0 to Process addition" << endl;
cout << "1 to Process randomization, division, multplication, power of and addition" << endl;
cout << endl;
cout << "Input: (0 or 1) ";
cin >> Method;
cout << endl;
T = GetTickCount();
for( I = 0; I <= J; I++ ){
if( Method == 0 ){
if( K > 0xFFFFFF) K = 0;
K = K + 1;
}else{
K = (rand() % 1) * 1000;
K = K * 2 / 3 * 5;
K = pow(K, 2);
GetLocalTime( &Time );
K = K + Time.wSecond;
}
}
T = GetTickCount() - T;
cout << "The time to process is: " << T << "ms" << endl;
return 0;
}
Note that I didn't do error checking on the input from the console because it is very simple code. If it was mission critical, I would have
Why not compare something like the ability to get real work done on real world projects? In other words, look at the bigger picture. Comparing a string sort may be interesting (um, maybe not), but in the grand scheme of things, does it really matter if one approach is 2us slower than another?
Don't just copy over the app by doing the same approach (api's, etc.) that you did in VB6. Do it by way of a .Net approach from the ground up. For graphics work, try using WPF and see if you can recreate the music clef using the WPF primitives.
