CWinApp()的构造函数定义在appcore.cpp中,CWinApp类定义在afxwin.h
构造函数:
CWinApp::CWinApp(LPCTSTR lpszAppName)
{
if (lpszAppName != <a href="https://www.baidu.com/s?wd=NULL&tn=44039180_cpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1dBn1uhnjwWnvDvuhcLnjbd0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6K1TL0qnfK1TL0z5HD0IgF_5y9YIZ0lQzqlpA-bmyt8mh7GuZR8mvqVQL7dugPYpyq8Q1cvPj63rHT4rHmkn10dPWm3Pf" target="_blank" class="baidu-highlight">NULL</a>)
m_pszAppName = _tcsdup(lpszAppName);
else

在appcore.cpp中。
追问
appcore.cpp在哪里打开(MFC)
追答
各个版本的位置和代码有差异。
一般都是在安装目录下,MFC是开源的,你可以在VS的VC安装目录下,找到绝大部分MFC框架的实现代码。
技巧:VS有个按目录搜索功能,指定为安装目录的MFC下,搜“CWinApp::CWinApp”
