運行時問題 ：
虛接口抽象類 遇到
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.
This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.
編譯問題：
具體dll函數遇到
DLL 找不到函數編譯連接時候。
實際是
DLL _stdcall。
vc
_cdecl 。#ifndef BUDLL
