Answer 1

#include <afx.h>

Answer 2

#include <afx.h> ,测试一下。

Answer 3

#include <afx.h> ,测试一下。 秘密

Answer 4

是HWND，而不是HWMDHINSTANCE,hPrevInstance  这里中间多了个逗号

Answer 5

是wndclass.hbrBackground而不是 wndclass.hbrBackgrond是GetStockObject而不是GETsTOCKoBJECT是TEXT而不是TExt小问题太多，只找到这

Answer 6

对于有问题的语句加了/**/注释然后另起一行写了修正后的语句#include<windows.h>/*LRESULT CALLBACK WndProc (HWMD,UINT,WPARAM,LPARAM);*/
LRESULT CALLBACK WndProc (HWND,UINT,WPARAM,LPARAM);/*int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE,hPrevInstance,*/
