VC6.0,创建窗口问题

为什么不显示呢
#include <windows.h>
#include <stdio.h>
LRESULT CALLBACK WinmyProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
);
int WINAPI WinMain(
HINSTANCE hInstance,
HINSTANCE hPrevIntstance,
LPSTR lpCmdLine,
int nCmdShow
)
{
WNDCLASS wndcls;
wndcls.cbClsExtra=0;
wndcls.cbWndExtra=0;
wndcls.hbrBackground=(HBRUSH)GetStockObject(BLACK_BRUSH);
wndcls.hCursor=LoadCursor(NULL,IDI_ERROR);
wndcls.hInstance=hInstance;
wndcls.lpfnWndProc=WinmyProc;
wndcls.lpszClassName="shisongyan";
wndcls.lpszMenuName=NULL;
wndcls.style=CS_HREDRAW;
RegisterClass(&wndcls);

HWND hwnd; hwnd=CreateWindow("shisongyan","www.163.com",WS_OVERLAPPEDWINDOW,0,0,600,400,NULL,NULL,hInstance,NULL);
ShowWindow(hwnd,SW_SHOWNORMAL);
UpdateWindow(hwnd);
MSG msg;
while(GetMessage(&msg,NULL,0,0))
{TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}

LRESULT CALLBACK WinmyProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
)
{
switch(uMsg)
{
case WM_CHAR:
char szChar[20];
sprintf(szChar,"char code is %d", wParam);
MessageBox(hwnd,szChar,"char",0);
break;
case WM_LBUTTONDOWN:
MessageBox(hwnd,"mouse clicked","message",0);
HDC hdc;
hdc=GetDC(hwnd);
TextOut(hdc,0,50,"chengxuyuanzhijia",strlen("chengxuyuanzhijia"));
break;
case WM_PAINT:
HDC hDC;
PAINTSTRUCT ps;
hDC=BeginPaint(hwnd,&ps);
TextOut(hDC,0,0,"www.BAIDU.COM",strlen("www.baidu.com"));
EndPaint(hwnd,&ps);
break;
case WM_CLOSE:
if(IDYES==MessageBox(hwnd,"zhendeguanbi?","message",MB_YESNO))
{
DestroyWindow(hwnd);
}
break;
case WM_DESTROY:
PostQuitMessage(0);
break;

default:
return DefWindowProc(hwnd,uMsg,wParam,lParam);
}
return 0;
}
