该程序是个绿色版，只有一个exe和三个DLL：
C:\CAD\CADe_SIMU.exe
C:\CAD\MFC42D.DLL
C:\CAD\MFCO42D.DLL
C:\CAD\MSVCRTD.DLL
用ollydbg调试，输入函数只是显示：
006AE05C .idata 输入 MFC42D.#1019
006AE164 .idata 输入 MFC42D.#1033
之类的，没法其知道是在哪里确定的窗口样式。
下断CreateWindowExa，回溯

不知道是不是在
5F42D59C |. 8B45 EC mov eax, dword ptr [ebp-14] ; |
5F42D59F |. 50 push eax ; |Style
确定style的值，这时候是
eax=00CF8000
MFC42D.#1658+0AA
但是最后形成的窗口样式值却是：54CFC000
不知道最后在哪里改变了？
