目的：快数定位全局对象的构造函数 类的虚函数表 MessageMap表
工具：IDA4.8 VC6SP6
1. Vc6迅速生成一个mfcdemo，基于dialog，整个程序由一个CWinApp子类和一个CDialog子类构成
2. 编译得到release\mfcdemo.exe
3. 给当前系统配置好symbol，用IDA4.80反汇编mfcdemo.exe
4. 通过IDA names页可以迅速找到下面这个表，显然，就是CWinApp子类的虚函数表。
没有名字的，就是没有找到符号的，为什么找不到？因为被我们重载了嘛。根据CWinApp的定义，
可以找到相关的被重载的虚汗数名字，注意：CWinApp<--CWinThread<--CCmdTarget<--CObject，虚汗数表需要从祖先分析起，然后累加
如CWinApp的虚函数表：

7.全局变量和构造函数
start-->initterm-->(pfn_Start,pfn_End)
pfn_Start就是第一个构造函数啦
pfn_End就是最后一个啦，可能是0结尾
最好看vc6sp6的源代码。
