运行之后只有进程没有界面是为什么。。
你的窗口回调函数在哪里？
WinSunPrnc在哪里？
#include <Windows.h> //Windows程序需要包含Windows的头文件
#include <stdio.h>
//可以通过MSDN查看回调函数的声明方式
LRESULT CALLBACK WinQinProc(HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
);
//WinMain.通过查看MSDN找到声明方式

你代码中指定的类名和你创建窗口指定的类名不一致，你创建窗口的函数CreateWindow应该会失败。
wndcls.lpszClassName =** "First MFC";//类名化;**
。。。。
hwnd = CreateWindow(**"First MFC 2015",**
我也在搞这个代码，搞得好苦啊！
你用BCompare去比较下看看
用BCompary比比看
