傻猫日志 Samool.com

今年年初的时候，其实我就有点想买点股票的，之前老婆一直吵着想入市去捞点油水，周围的朋友都通过股市如何如何赚钱了，07年大牛的时候身边有一些朋友也捞了不少，可怜当时没有多余的资金，炒股不如自己搞点实业来得踏实。于是也就错过了一波大好行情，去年6，7月份的时候我们公司的股票600804才15块，年初的时候涨到20左右，本来计划买点的，结果年初去夏威夷土豪了一把，第一次出国买了不少东西，于是把积蓄都用了，年初那几个月还过的紧巴巴的，花了两三个月才恢复元气。后来公司的股票涨到30块，就在想啊，如果去年年中的时候买个20万股票，这一下就翻一倍了，再后来涨到50块钱，就更后悔当时没有买了。。。。

当大盘一路冲高，冲到4000点以上以后，我知道风险太大，要亏。。。所以一直观望着，5月底开始，大盘一直暴跌，到4000点的时候，我决定入市了，准备抄底了，6月底开户，第一天投了10万，结果第二天就赚了1万多，爽啊，于是再投10万，结果就开始每天跌停的日子，跌停了继续接盘买。。。再买。。再买，直到打光所有子弹。。。。。。后来国家救市，公司的股停牌了两星期，复盘后连续3个涨停，回本了不少，再涨了几天，基本上就回本了，其实人的心里啊，当亏本的时候就想回本，回本之后就想赚点再走。。。于是见证了为国护盘，千股涨停，千股跌停这些只有在A股才有的奇葩事情。。

elphi/C++ Builder采用控件拖放的方式来完成界面的设计，并和事件联系起来。而这些信息以资源（RCDATA）的方式存放于可执行文件中。DeDe便利用这个原理进行反编译，获取相关信息，将界面与事件联系关系还原，但事件的汇编代码不能还原。DeDe公开了源代码，感兴趣的读者可以研究一下。

1．主要功能
用DeDe可以查看Delphi程序窗体的属性，可以查看按钮对应的事件，并将事件代码反汇编出来，其能识别出Delphi库函数，具有良好的可读性。另外，还可以把事件输出到map文件中供其他工具使用。

2．配置
（1）DSF文件

①DSF文件的含义

DSF文件内容来自不同版本BPL库文件的输出符号表。DeDe反汇编引擎使用这些符号表对生成的ASM代码文件添加类成员方法调用的注释，这非常类似于IDA Pro的FLIRT技术。如果没有加载任何BPL符号表文件，对BPL类的调用就无法以注释的格式说明。

②加载DSF文件

经由“File/Load Symbol File”菜单，就可加载所需要的DSF文件。程序若能正确识别出相应版本的Delphi程序，会自动加载DSF文件。若希望每次启动DeDe的同时自动加载若干DSF文件，选中“Options/Configuration”菜单，在Symbols选项卡中就可完成本项工作。如果想查看包含在某个特定DSF文件中的输出符号表，选择“Options/Symbols”。

③为何需要创建DSF文件

处理使用自定义构件（即不是Delphi安装的构件）的程序时，如果有这些自定义构件的BPL，并且为它们创建了DSF文件，那么DeDe将会注释所有对这些自定义构件的调用。创建DSF的速度也是很快的。

1.程序窗口句柄检测
原理:用FindWindow函数查找具有相同窗口类名和标题的窗口,如果找到就说明有OD在运行
//**
//通过查找窗口类名来实现检测OllyDBG
//**
function AntiLoader():Boolean;
const
OllyName='OLLYDBG';
var
Hwnd:Thandle;
begin
Hwnd:=FindWindow(OllyName,nil);
if Hwnd<>0 then
Result:=True
else
Result:=False;
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
if AntiLoader then
MessageBox(Handle,'找到调试器!','提示',MB_OK+MB_ICONINFORMATION)
else
MessageBox(Handle,'未找到调试器!','提示',MB_OK+MB_ICONINFORMATION)

在通常情况下使用delphi设计程序，都是将字符串、图像等资源直接使用delphi提供的vcl控件加到*.dfm中，这样做会合修改这些资源时带来 不便，如果资源被多次引用，这些资源在程序启动时都被加载到内存中，非常耗费系统资源。因此，这就需要一种新的引用资源的文件：资源文件。资源文件就是将 一些资源，如字符串、图像等信息进行编译，然后在程序中引用编译后的资源文件，最后和源程序一起编译生成可执行文件。由于在资源文件中的资源是在需要时加 载，因此，比较节省系统资源，而且，如果要做国际化版本的系统，只需要将资源文件一换，重新编译即可。下面就详细介绍delphi中资源文件的建立和使用。
