VC++创建一个Windows窗口程序本文为《VC++深入详解》第一章的笔记创建一个完整的Windows窗口程序主要步骤为 WinMain函数的定义创建一个窗口编写消息循环编写窗口过程函数窗口的创建：消息循环：在创建、显示、更新窗口之后，我们需要编写一个消息循环，不断从消息队列中取出消息，并进行响应。 GetMessage(),Peekmessage()从消息队列中取出消息，并保存在消息结构体中阅读详情

f:\cyuyanyu\vc++英文版\[大家网]visual.c++.6.en[www.topsage.com]\vc98\include\winuser.h(39) : fatal error C1004: unexpected end of file found

下面是winuser.h中的一段代码
#include <stdarg.h>
#ifndef NOUSER

typedef HANDLE HDWP; (以上两个错误都指向这一行)
typedef VOID MENUTEMPLATEA;
typedef VOID MENUTEMPLATEW;
#ifdef UNICODE
typedef MENUTEMPLATEW MENUTEMPLATE;
#else
typedef MENUTEMPLATEA MENUTEMPLATE;
#endif // UNICODE
找不出原因,请大家帮帮忙
