不编译就显示的错误：

这个问题需要你自行研究
首先你没发代码，鬼都不晓得你在讲什么

其次，即使你发出代码，估计也没人会
现在研究mfc的好像不多

把windows sdk 版本从 10.0.18362.0改为10.0.17763.0后，第一个错误没有了，
但第2,3个错误依然存在，大神能不能提醒一下主要修改哪些属性项？

有啊：
int WINAPI WinMain(
HINSTANCE hInstance,    // handle to current instance
HINSTANCE hPrevInstance, // handle to previous instance
LPSTR lpCmdLine,    // command line
int nCmdShow            // show state
)
