VC 的问题! (入门级)

刚开始学习VC++ 今年天好不容易把代码打进去了,编译却有fatal error
对着书差了半天,没错啊!? 各位大哥们,帮我看看着个最简单的代码的问题出在哪???
#include<windows.h>
LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM); //窗口函数说明
提示说这下面的入口函数有错误!!!!
int WINPAI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInst,
LPSTR lpszCmdLine,
int nCmdShow)
{
HWND hwnd;
MSG Msg;
WNDCLASS wndclass;
char lpszClassName="456";
char lpszTitle[]="MY windows!";

//窗口类的定义
wndclass.style=0; //窗口类型
wndclass.lpszMenuName=NULL; //窗口中无菜单
wndclass.lpszClassName=lpszClassName; //窗口类名为lpszClassName
wndclass.lpfnWndProc=WndProc; // 窗口处理函数为 WndProc
wndclass.hInstance=hInstance
wndclass.hIcon(NULL,IDI_ERROE);
wndclass.hCursor(NULL,IDC_ARROW)
wndclass.hbrBackground(WHITE_BRUSH);
wndclass.cbWndExtra=0;

#include<windows.h>
