Answer 1

lineInitialize这个函数不存在，没有写代码

Answer 2

我只是加了个函数 lineInitialize(
        lphLineApp,  
        hInstance,    
        lpfnCallback,  
        lpszAppName,     
        lpdwNumDevs     
        );
然后#include "Tapi.h"
在TOOLS->OPTIONS里也加了lib,怎么还有错？

Answer 3

必须在project->setings->link->object/library modules->加上你的lib
或project->add to project->Files->加上你的lib
