How to control CMD console?

The language is relativ, only understand it

 

normally I agree, but when goal is to produce basic, asm code in as few lines as possible, IMHO anything besides asm/C is bad. C printf() takes just a few lines of asm, but c++ cout << compiles into 70+. Same thing (and worse) w/ C++ vectors vs. C arrays, C strings vs. (very) high level c++ strings, etc. i dont hate c++ (ok maybe I do :) ), but it's a big complex language for big complex projects, not just a few winapi calls. /rant

Well, obviously I disagree with you :D C++ can do what C can and more if needed (STL).

 

C++ printf() should make the same code as C printf(), there is no difference.

Hi guys,


 


so I think ASM (masm & winasm) is the easiest coder language or not?I thought so or are others easier?


 


@ raggy


 


Try again so I did delete some PMs now.

LCF you make all with Olly and multiasm and you can Asm .


 


So write in Asm :prop:  is easier for you


You can write in Masm or other Assembler without High Level ( If/else)

but printf() isn't c++, it's part of libc. rewrite the code i wrote here earlier in pure c++ & watch how big it gets. "c/c++" is a very misleading terminology. also, printf() will not work w/all c++ compilers.

 

i agree, asm is easiest (but in practice its slow as hell to write large projects in 100% asm and high level stuff like structs, if/else, while, etc make development much faster w/out adding unnecssary instructions), like mentioned do what works best for u, masm, c, c++, html, whatever

If you think those are the best for you then you should keep using them :) An alternative might be PureBasic. See Teddy's great blog about it: https://forum.tuts4you.com/blog/27/entry-146-purebasic-adventures/

In fact std::printf is part of the C++ standard library: http://en.cppreference.com/w/cpp/io/c/fprintf :)

This is pure c++:

#include <cstdio>int main(){    std::printf("Hello, world!\n");    return 0;}
or if you prefer:
#include <cstdio>using namespace std;// this will retrieve args from the pspint main(int argc, char *argv[]){  printf("%s %s %s\n", argv[0], argv[1], argv[2]);  fflush(stdout);  getchar();	  return 0;}

if u compile the c++ code w/ mingw g++, using std::printf() the exe will be 464kb exe . if u compile the same exact printf() C code w/mingw gcc, the exe will be 15.4 kb. both link to msvCrt.... c++ has junk that c doesn't...


 


and no, that isnt pure c++ because you're using Cstdio.h. traditional C++ uses << to write to console, not printf()... is ur point that c++ doesnt produce more junk?


 


fyi - i wasnt even talking about that program, i meant rewriting the masm code in pure c++ to see a whole bunch more unnecssary stuff... ; )

This topic is being digressed, I would say the best answers can be found in "The Art of Assembly Language" book :)

The C++ junk you're talking about can be removed by changing some options before compiling


and almost all of these pieces of code, aka junk, are somewhat beneficial


 


@LCF


I advice u to read Iczelion's tutorial Series ... they r the best ever


and I always prefer to use RadAsm than WinAsm

Congratulations, your compiler produces junk. My compiler generates two executables, the C one is 8496 bytes, the C++ one is 8536 bytes...

 

and no, that isnt pure c++ because you're using Cstdio.h. traditional C++ uses << to write to console, not printf()... is ur point that c++ doesnt produce more junk?

If you use std::cout you will probably get some overhead indeed, but that doesn't change anything about the fact that C++ is supposed to be backwards-compatible with C, which means <cstdio> is included in the C++ standard (making it part of C++).

 

fyi - i wasnt even talking about that program, i meant rewriting the masm code in pure c++ to see a whole bunch more unnecssary stuff... ; )

http://www.cplusplus.com/reference/cstdio/- <cstdio.h> (stdio.h) - C library to perform Input/Output operations

Yep, C library is still part of C++.

edit - http://stackoverflow.com/questions/2872543/printf-vs-cout-in-c- nearly every answer will acknlowledge that printf() is C... and by pure c++ I mean not using anything from libc, instead of c strings w/pointers, use std::wstrings, instead of FILE*, file streams, instead of arrays, vectors, etc and the resulting compiled code will be much larger... hence why C/asm is the defacto official language of anything where performance is important (embedded, kernel drivers, etc)

Almost anything you can do with C you can do with C++. I write kernel drivers in C++, produces pretty much the same ASM, except that you can use constructors/destructors to automatically free memory/handles etc. Makes programming a lot safer ;)

If your point was that using <iostream> to output to the console generates overhead you are completely right (although you get other things back from it). Saying <cstdio> is not pure C++ is just incorrect, this is the only part I try to get clear.

Hi again,


 


yes I know the Iczelion tutorials but as I said its not really easy for me to understand them completely.Also the tuts are written into any black background (can't read very long on black or other dark colors) so can I change this anyhow to white background etc or do you know any re-write of this tutorials?


http://win32assembly.programminghorizon.com/tutorials.html


 


What is the different between RadAsm / WinASM or MASM or why is RadASM better etc?


 


So PureBasic dosen't look easy too. :) So I think ASM is already ok so far.So I am already happy that I can handle this language more or less.


 


Ok I got a another question:


----------------------------------------------------------------


So I have created a normaly proc with called by DialogBoxParam.Now the proc get always access if I press anything in the Dialog etc (all ok so far).The question I have now is....


 


What is if I wanna create for exsample a clock (like this 19:54:21) and put this into the dialog somewhere,so how do I now update this clock for each second?You know what I mean right?So the clock now gets only updated if I press anything on the dialog then it will access my proc and there it can access the code to update the clock again but if I don't press anything on dialog then clock get not updated etc you know what I mean right.So how to handle this problem?Have I to create any single thread for this and if yes do have a short ASM exsample?Sorry for asking again but I don't know it. :)

Masm is only a compiler == Ml

 

Winasm /Radasm is only a Editor like Notepad or other editor

You can coding masm in Visual studio or Notepad (++) or other Text editor

 

Radasm ist better than Winasm? no is only a other Ide and support other function and languages.

But i find Radasm better

 

But that have i tell you 100x :prop:

Ah ok thanks again for the remembering but you know I did forgot it again for 100x too. :) But I think this time it will working better to stay on the ball with WinASM and to keep some more in my head than anytime before.Maybe at the end of this year I could code almost good so that I also can create any more complex stuff (Maybe a Unpacker etc). ;)

You should use CreateThread for this.

See my attached example code (C++), you can see in olly how it work with assembler.

Hi again,


 


thanks for the exsample code also if its written in C but after some time I got it working now.Maybe not written very good but it works....



STIME SYSTEMTIME <> CLOCKTHREAD proto timeText db 40h dup (0)
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
CLOCK proc invoke GetDlgItem,HWNDPROC,1169
mov hwndLabel,eax
invoke CreateThread,0,0,addr CLOCKTHREAD,hwndLabel,0,0

LOOPA:
invoke GetLocalTime,addr STIME xor eax,eax
mov ax, [STIME.wSecond]

add esp, 0Ch
invoke SetWindowText,hwndLabel,addr timeText
invoke Sleep,1000
jmp LOOPA Ret
CLOCKTHREAD endp end main

Is ok so or?But I had to push the 3 times manually + adding 0C bytes too after wsprintf API.I tried to set the 3 time paramters on the wsprintf API but it will just push words insread of dwords etc you know.Also I couldn't use a while / endif command to make the infini loop (no idea why) and there I just used jmp label.The HWNDPROC I did copy before from the DlgProc main proc.If you know how to write this better or more un-complex then just tell me.

lcfat - im not a masm expert either, but if u push args manually (w/out using invoke) then "call" manually, otherwise ml.exe (the compiler) will not adjust the stack pointer properly after call & who knows whatll happen. so either use invoke w/all arguments like mr x code or do it like this, but dont mix them



.while (1)
invoke GetLocalTime, addr Stime lea eax, [Format]
lea esi, [Lander]
movsx ebx, Stime.wSecond; or mov bx, Stime.wSecond
mov cx, Stime.wMinute
movsx edx, Stime.wHour
push ebx
push ecx
push edx
push eax
push esi
call crt_sprintf ; this is the same as - invoke crt_sprintf, esi, eax, edx, ecx, ebx
add esp, 14h ; or invoke crt_sprintf, addr Lander, addr Format, [Stime.wSecond], etc, etc
; esp is adjusted according to how many args. if u give invoke 2 args, stack pointer
; will be set to 2 args (8) when true value is 5 (14) push 1000
call Sleep etc etc etc .endw

Hi guys,


 


thanks again for the example codes. :)


 


One question about the hWin....



invoke GetDlgItem,hWin, IDC_LBL_TIME

...so what is if I have this code in any other proc XY and not in same proc as DlgProc.At the moment I have to copy this hWin into any variable which I then use in my other proc.Is there also a other way to use any hWin etc from proc xy also in any other procs yx?


 


PS: Yes I have also added extra that stack values 0C of 3 pushes before but I also have changed this now and call all with the API. :)


 


One another thing: So the notepad.exe is in all Windows version in system folder to find right?So I mean you can call notepad.exe directly without path (same as all other files which are stored in system / 32 folder).So I made this short code what should work on all systems (XP and higher)



invoke GetStartupInfo,addr StartInfo
invoke CreateProcess,0,chr$("notepad.exe Logfile.txt"),NULL,NULL,TRUE,NULL,NULL,NULL,addr StartInfo,addr PI

Just using direct names without paths.Logfile is in same folder as my app and notepad (same name on all systems) I can call from anywhere not only from XP right.So then I don't need to use extra path datas.


 


Thanks

You can do this with a global variable. Put something like this:

hWinGlobal dd ?

Yes, it will work on other versions of windows too.

Hi again,


 


ok thanks again guys.


 


So how does hWinGlobal work?How to use / declare it?I mean I use a dialog resource and a main DLG proc "DlgProc proc hWnd:HWND, uMsg:HWND, wParam:WPARAM, lParam:LPARAM" and the hWnd is for this main Dialog which I just can use in this same proc only.How to make it global now?At the moment I have this...



DlgProc proc hWnd:HWND, uMsg:HWND, wParam:WPARAM, lParam:LPARAM
mov eax, hWnd
mov HWNDPROC, eax ; make a copy
.............
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
CLOCK proc
invoke GetDlgItem,HWNDPROC,1169 ; use copy in other proc
mov hwndLabel,eax
invoke CreateThread,0,0,addr CLOCKTHREAD,hwndLabel,0,0

Sure, you can do so by copying them into MS Word files (offline) or into Google Docs (online).

 

 

 

is RadASM better ?

A question of personal preference; however, I think that RadASM is so handy.

 

 

 

if u push args manually (w/out using invoke) then "call" manually

Why do we call them manually since we have invoke which cleans the stack automatically ?? It's even more readable !

Hi again,


 


today I wanna try the RadASM tool (found also a version on my HDD) but I have problems to find the resources editor.I see no visual Mode on/off button as I have in WInASM.So how to get a visual mode to see in RadASM?

hmmm no visual mode!Why this?How to build then any dialogs etc? :) Ok if RadASM has no visual mode as WinASM then its nothing for me so I can't build my resources blind etc.
