does any body have code to convert binary file to text file ? for example i have file (binary file) that contain binary ascii for example AB??.... and so on i want to translate it to file text that contain number represents that binary ascii above so it must contain : 65 66 and so on if anybody have the code please send me please :->

This is a fairly simple task. First, you open your 'binary' file, and load a specific number of bytes. The classic way is to load either a quad word (8 bytes) or a paragraph (16 bytes), but feel free to use your own system (32 bytes, 256 bytes, etc.) I will say it's better to put an even binary (2, 4, 8, 16, etc.) number on a single line. This will make the file a little bit less confusing, and also make it easier to figure out addresses. Once you've done that, simply use wsprintf (or another number displaying routine) and copy the text into a destination file. Repeat this until the file is finished. You can even add base addresses, or an ASCII output (like some debuggers do), but, as you can see, the routine is really not that difficult.

Dude, use the 'code' statements for adding code. Like so:


     .const
       IDM_OPEN equ 1
       IDM_SAVE equ 2
       IDM_EXIT equ 3
       MAXSIZE equ 260
Thats hard on the eyes, nevermind debuggin it... NaN

I haven't tried, but I guess this is the error:

mov ecx,eax
mov esi,pMemory
looping:
   cld 
   lodsb
   invoke wsprintf,addr binary,addr template,al
   invoke WriteFile,hFileWrite,addr binary,6,ADDR SizeWritten,NULL
loop looping
ecx is used as a counter in the loop, but both API functions (wsprintf, WriteFile) don't preserve ecx. Either push ecx before the API functions and pop it after them, or use some other loop:

mov esi, pMemory
mov edi, esi
add edi, FileSize
cld 
.WHILE esi

My thank go out to Thomas that give me alternative way and i have tried but there was still got the same message :-< i change my code with yours like this :

invoke GetFileSize,hFileRead,NULL
mov esi, pMemory
mov edi, esi
add edi, FileSize
cld 
.WHILE esi
but there was an error message like this : (although i got file with correct number represents binary number) the instruction at bla bla .. referenced memory at bla bla .... can not read memory does any body help ?

i found that the problem is in wsprintf function because if i mark it ;invoke wsprintf,addr binary,addr template,al there is no message error again but as a result we fail to convert binary ascii to number i don't know what is going on inside wsprintf ? it seems it fails to read or convert number in memory :-<

There is no error again after i change wsprintf with dwtoa function in masm32.inc. So it was correct that wsprintf is the main problem. i am curious if we can translate binary exe to text file and convert it again to binary and still run. may be this is what compiler done i don't know

Funnily enough dwtoa calls wsprintf! But to anwser your question, - there's no reason why you can't convert a program to hex string, then back into an .exe file again, in fact this will work for any sort of file even an ascii one ! . Reasons for doing it however would be odd, I mean, why bother? the .exe is a lot smaller... umbongo

it is not about smaller or not concerned with files but i need this converting to analyse files contained digital stuff like sound or image that may be easier for the next processing. I just take an example for exe file. Ok may be i am a stupid person or odds guy, i still newbie

You could try using a hex dump program, there are 100's of those around :) Umbongo

thank's for your suggestion :-> but only human being can decide which is which. by the way where can i find a routine in win32asm connected with signal processing ? is it possible ?
