关于windbg调试汇编原程序的问题,谢谢.
windbg我不太会用,在网上又没找到相关的东西,谢谢各位帮忙了.我就想问一下调式一个普通汇编程序的过程.下面这个程序是我在命令提示符下用MASM611编译的(命令:make32 addsub),然后用 File->open executable...装入addsub.exe,结果就是下面的样子了.
下面是原程序:
TITLE Add and Subtract (AddSub.asm)
; This program adds and subtracts 32-bit integers.
; Last update: 2/1/02
INCLUDE Irvine32.inc
.code
main PROC
mov eax,10000h ; EAX = 10000h
add eax,40000h ; EAX = 50000h
sub eax,20000h ; EAX = 30000h
call DumpRegs
exit
main ENDP
END main
下面是"command"里面的内容,请问该如何改,谢谢了.

OllyDGB是个不错的调试器，专门用来调试Win32程序。基本原理是利用Windows的调试函数。Top
