程序中获取当前文件夹路径

1.使用APi函数GetModuleFileName

char path[MAX_PATH];
GetModuleFileName(NULL, path, MAX_PATH);        //获取到完整路径如：E:\Tools\qq.exe
*strrchr(path,'\\') = '\0';                                                      //截取路径E:\Tools

2.MFC

char path[MAX_PATH];
memcpy(path, AfxGetApp()->m_pszHelpFilePath, MAX_PATH)       //获取到完整路径如：E:\Tools\qq.hlp
*strrchr(path,'\\') = '\0';
