beginner and strings

[yaki]

hi all
I am a beginner...and I think that works  with  strings is important.
I work with a sniffer and I have an output like 1DA0206548....and I would like to reformat this output to have %1D%A0%20%65%48

any help will be appreciate

Thanks in advance

yaki,

I moved the topic to the Campus so you had a better chance of a reply. Just make sure that the question you are asking is not cracking or reverse engineering related as we cannot allow that under the forum rules.

Hi,

try this

Code Select Expand

ConvertString PROC pszOut:DWORD, pszIn:DWORD

push edi
push esi

mov edi, pszOut
mov esi, pszIn

@@:

mov ax, [esi]
or  al, al
jz  @F
or  ah, ah ; These lines aren't needed if the input
jz  @F ; string is certain to be even in length

shl eax, 8
mov al, '%'
mov [edi], eax

add edi, 3
add esi, 2
jmp @B

@@:

mov [edi], byte ptr 0

pop esi
pop edi

ret
ConvertString ENDP


It's not optimised or anything, but it works.

Hope that helps,
Ossa

hi
it is not the cracking or hacking but a simple strings manipulation.
thanks Ossa
