请教编译时找不到“windows.h”是什么原因
我是初学者,刚编了个简单的程序,编译时出错,请前辈们帮我看一下:
源程序:
#include<windows.h>
LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInst,LPSTR lpszCmdLine,int nCmdShow)
{
HWND hwnd;
MSG msg;
WNDCLASS wndclass;
char lpszClassName[]="窗口";]
char lpszTitle[]="My_Windows";
wndclass.style=0;
wndclass.lpfnWndProc=WndProc;
wndclass.cbClsExtra=0;
wndclass.cbWndExtra=0;
wndclass.hInstance=hInstance;
wndclass.hIcon=LoadIcon(NULL,IDI_APPLICATION);
wndclass.hCursor=LoadCursor(NULL,IDC_ARROW);
wndclass.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH);
wndclass.lpszMenuName=NULL;
wndclass.lpszClassName=lpszClassName;
if(!RegisterClass(&wndclass))
{
MessageBeep(0);
return FALSE;
}
hwnd=CreateWindow(
lpszClassName,
lpszTitle,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
hInstance,
NULL);
ShowWindow(hwnd,nCmdShow);
UpdateWindow(hwnd);
while(GetMessage(&Msg,NULL,0,0))
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wparam;
LRESULT CALLBACK WndProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
switch(message)
{
case WM_DESTROY:
PostQuitMessage(0);
default:
return DefWindowProc(hwnd,message,wParam,lParam);
}
return(0);
}
编译出错信息为:
-------------------Configuration: exec - Win32 Debug--------------------
Compiling...
e1.cpp
e:\study\vc练习\exec\e1.cpp(1) : fatal error C1083: Cannot open include file: 'windows.h': No such file or directory
Error executing cl.exe.

请大家指点,多谢!
