刚学VC++，照抄一段代码，出了问题，看一下。。

#include<windows.h>
#include<stdio.h>

LRESULT CALLBACK WinSunProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
);

int WINAPI WinMain(
HINSTANCE hInstance,
HINSTANCE hprevInstance,
LPSTR lpCmdLine,
int nCmdShow
)
{
WNDCLASS wndclass;
wndclass.cbClsExtra=0;
wndclass.cbWndExtra=0;
wndclass.hbrBackground=(HBRUSH)GetStockObject(BLACK_BRUSH);
wndclass.hCursor=LoadCursor(NULL,IDC_CROSS);
wndclass.hIcon=LoadIcon(NULL,IDI_ERROR);
wndclass.hInstance=hInstance;
wndclass.lpfnWndProc=WinSunProc;
wndclass.lpszClassName="abc";
wndclass.lpszMenuName=NULL;
wndclass.style=CS_HREDRAW | CS_VREDRAW;
RegisterClass(&wndclass);

HWND hwnd;
hwnd=CreateWindow("abc","´°¿ÚÃû×Ö",WS_OVERLAPPEDWINDOW,
0,0,600,400,NULL,NULL,hInstance,NULL);
