hello i'm a newbie in asembly programming...
Could any one help to solve this code
.386
.model flat,stdcall
option casemap:none
include \masm32\include\windows.inc
include \masm32\include\kernel32.inc
include \masm32\include\masm32.inc
includelib \masm32\lib\kernel32.lib
includelib \masm32\lib\masm32.lib
.data
hallo db "Hello World" , 0
.code
start:
mov ecx,6
_tes: invoke StdOut, addr hallo
Loop _tes
invoke ExitProcess, 0
end start
how to make it loop 6 times only
sorry my english is not good
** sorry i think i got a wrong thread to discuss diz code...
that doesn't work because the ecx register that is used by loop instruction is not prezerved before entering in StdOut procedure.
I bet this will work
__tes:
push ecx
invoke StdOut, addr hallo
pop ecx
Loop __tes
the thing is, even if there you see just aline of code (invoke StdOut ...), in fact the code that is executed before pop ecx may have hundreds or thousands of instructions that - you can safelly assume - will modify the value stored in ecx. As a rule, you can rely on ebx, esi and edi that will have same value before and after the call, and you may assume that eax and ecx will have diffrent values. You, too, must preserve ebx, esi and edi if you use any of them in a procedure (later, you will discover that you are not required to do this always, but, for now, it's safer this way).
HTH :U

Thx bro it's work :U.
is there a thread to a newbie code like this ?

Ow...this the right place...
Do u have a good reverence book for a newbie?
cause the TASM book is not suitable with masm :((there is no masm32 book in the book store here).
A great place to start coding in asm for Windows are the Iczelion Tutorials (http://win32assembly.online.fr/tutorials.html)
Have a look.
