一直在用OD，但是但是OD的原理是啥？那些数据怎么来的？
于是，就花了几天用OD调试了一下OD，并写了点心得。呵呵。
【名称】 OD分<vb_highlight>析被调试进程的数据来源
【版本】 。\OllyICE\原版\英文原版\OLLYDBG.EXE v1.10
【工具】 IDA，
下面所以贴出来的代码都是基于 OLLYDBG.EXE v1.10英文版。可用IDA逆向参考。地址一定是匹配的。
【分<vb_highlight>析时间】 2010-09-22
【OD的数据】
数据表：
ModuleList，模块列表。
ThreadList，线程列表。
HeapList,堆内存列表。
MemoryList,内存列表。
WindowList,窗口列表。
HandleList,句柄列表。
PatchsList,补丁列表。
CallStackList,回调列表。
BreakPointList,用户断点列表。
RefrencesList,字符串参考列表。
RunTraceList, 运行跟踪列表。
SourceList， 源代码。
【枚举】
OD的大部分数据来源，是通过对被调试进程的枚举而获取的数据。
+ 下面是枚举的API描述：
线程枚举：可以得到当前操作系统的全部的线程，只能得到线程ID，对线程操作需要线程句柄，
句柄只能用 <jmp.&KERNEL32.WaitForDebugEvent>,调试事件才可以得到。
hSnapShot:=CreateToolHelp32SnapShot(TH32CS_SNAPTHREAD,Pid);
Thread32First(hSnapshot,lpte);
Thread32Next (hSnapshot,lpte );
进程枚举：
CreateToolHelp32Snapshot(TH32CS_SNAPPROCESS, 0);
Process32First(FSnap, PE)
Process32Next(FSnap, PE);
模块枚举：
hSnapShot:=CreateToolHelp32SnapShot(TH32CS_SNAPMODULE,Pid);
Module32First(hSnapShot,lphl)
Module32Next(hSnapShot,lphl)
【OD的这些数据的基本操作】
首先，OD通过进程枚举获取进程列表。
其次，开始创建，添加数据。
+ 创建数据池：

一直在用OD，但是但是OD的原理是啥？那些数据怎么来的？
于是，就花了几天用OD调试了一下OD，并写了点心得。呵呵。
【名称】 OD分<vb_highlight>析被调试进程的数据来源
【版本】 。\OllyICE\原版\英文原版\OLLYDBG.EXE v1.10
【工具】 IDA，
下面所以贴出来的代码都是基于 OLLYDBG.EXE v1.10英文版。可用IDA逆向参考。地址一定是匹配的。
【分<vb_highlight>析时间】 2010-09-22
【OD的数据】
数据表：
ModuleList，模块列表。
ThreadList，线程列表。
HeapList,堆内存列表。
MemoryList,内存列表。
WindowList,窗口列表。
HandleList,句柄列表。
PatchsList,补丁列表。
CallStackList,回调列表。
BreakPointList,用户断点列表。
RefrencesList,字符串参考列表。
RunTraceList, 运行跟踪列表。
SourceList， 源代码。
【枚举】
OD的大部分数据来源，是通过对被调试进程的枚举而获取的数据。
+ 下面是枚举的API描述：
线程枚举：可以得到当前操作系统的全部的线程，只能得到线程ID，对线程操作需要线程句柄，
句柄只能用 <jmp.&KERNEL32.WaitForDebugEvent>,调试事件才可以得到。
hSnapShot:=CreateToolHelp32SnapShot(TH32CS_SNAPTHREAD,Pid);
Thread32First(hSnapshot,lpte);
Thread32Next (hSnapshot,lpte );
进程枚举：
CreateToolHelp32Snapshot(TH32CS_SNAPPROCESS, 0);
Process32First(FSnap, PE)
Process32Next(FSnap, PE);
模块枚举：
hSnapShot:=CreateToolHelp32SnapShot(TH32CS_SNAPMODULE,Pid);
Module32First(hSnapShot,lphl)
Module32Next(hSnapShot,lphl)
【OD的这些数据的基本操作】
首先，OD通过进程枚举获取进程列表。
其次，开始创建，添加数据。
+ 创建数据池：
.text:00478013 loc_478013: ; CODE XREF: ShowProcessList+5Fj
.text:00478013 push 0 ; FuncAddr2
.text:00478015 push offset FuncOfProcessTable ; FuncAddr1

.text:0047801F push 310h ; RecordSizeOfItem
.text:00478024 push offset aProcessTable ; "Process table"
.text:00478029 push offset ProcessTableClass ; pResultDataPointer
.text:0047802E call _Createsorteddata ; ：创建存储数据块(ProcessTable,ThreadTable,ModuleTable,MemTable.....)
.text:0047802E ; ：pResultDataPointer= 新数据块指针
