Hello there, long time I'm not here, but I can't get into this forum where I usually access from. Firstly I guessed that anyone was playing banning ips, but now I think it is ok: less time lost Wink... Well, a floor demo here... Yeah... See you up until two or three months Smile

COOL ... but I can't RTFS (or is this the next disassembling challenge?) :-\

DOS386,

It's (somewhat cryptic) example how not to use extended headers.

E.g. WinMain() unnecessarily establishes stack frame (it doesn't use neither parameters nor locals) and saves/restores ebx/esi/edi (they're not modified through its execution). It does some other weird stuff, like after GetMessage(): cmp eax, 1 / jb return_wParam_to_caller / jnz call_GetMessage_again. Looks innocent because hWnd, wMsgFilterMin and wMsgFilterMax are all zero, but with filter this may lead to dead loop when GetMessage() returns -1.

WndProc() saves/restores registers too, but they're tampered one call deeper. Some functions it calls indeed modify esi, but one of them apparently went paranoid: it saves not only those registers, but ecx & edx too, to be extra safe. Wink

Agree with HaHa, DOS386 and baldr!

Just as a starting point.

For those who prefer to assemble their
own source when presented with an EXAMPLE.

Good work, Walter, very good. Smile

BTW, I wonder, have you used IDA to disassemble?

MHajduk,

I do. It's invaluable tool (though costly).

Walter,

You're just awesome! I can't handle that code w/o urge to puke. Wink

@MHajduk

> have you used IDA to disassemble?

Wonder what gave that away?

Unoriginal variable names?
Bad label names?
But yes and yes, that tool is good.

What really should be here are examples
that have the quality of what you write!

That is, orginal code, good variable names
and comments. You can learn much from
example code.

@baldr

Just shows much of what you've pointed out already.

@HaHa

I like your definition of Example.

"It can't be considered an example without source.

Without proper comments it's just a source waiting for compilation. Not an example.

I made a few (successful) attempts to disassemble some codes posted here, on this forum (one of them was avcaballero's too, but not the presented above), so I got the overall style of the IDA's disassembly listings. Wink

Absolutely agree with you at that point. Smile

Walter, good work!, you have entered in the lamers club. I have noticed that you have deleted any copyright notice... I wonder if you know that it is an illegal activity, at least in my country, don't know in yours... Anyway, don't
worry, I will ask nothing of course, after all I was to release it on free, and nothing new under the sky.

Do you create anything or only work on hacking things?

I don't like persons that recover things compulsively, have a glance at them and throw to the bin... neither persons who don't credit... It is a matter of personal culture, I guess.

Well, I'm working on windows demo tutorial and, when finished, uploaded it to my own site as others that I did before; but looking guys as you, removed me the desire to share it.

Don't know what happens with this forum, but lately I can't get into here. In light of recent events, I think that would be best. I think that fasm is one of the best assemblers, other thing is people here...

Have a nice day fellows

PD. Surely I can't answer you because it is hard to me to get into here... Anyway any news from me I take care of take it to another site Wink

avcaballero: Muy bien, Amigo! Smile Tiene el codigo?

Check out comrade's graphics examples: http://comrade.ownz.com/intros.html He's really good. I was inspired by him to create a website and share my code.

Have a good day.

PS: Previews of my latest project: http://sungod777.zxq.net/codeviewp.jpg Improved themes, dynamic font zoom, etc. R.I.P Stale-Lib. Deprecated by the power of Z77.

Yeah, not just a little DOS example that uses the internal PC speaker. Not impressed. Not "original", nothing special. Practice what you preach. What avcaballero presented here is infinitely superior to anything your small mind could ever produce.
