大牛们好，windows编程RegisterClass()返回为0，感觉好诡异~~~~

搞了一下午，实在是不行了~~~请大牛们给予指点吧~~~~~~~在下刚刚接触WINDOWS编程
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nShowCmd)
{  
   MSG msg;
   WNDCLASSEX wcApp;
   wcApp.lpszClassName="ss";
   wcApp.cbSize=sizeof(wcApp);
   wcApp.CS_VREDRAW;
   wcApp.hInstance=hInstance;
   wcApp.cbWndExtra=0;
   wcApp.cbClsExtra=0;
   wcApp.hCursor =LoadCursor(NULL,IDC_ARROW);
   wcApp.hIcon =LoadIcon(NULL,IDI_APPLICATION);
   wcApp.lpfnWndProc=WndProc;
   wcApp.hCursor=LoadCursor(NULL,IDC_ARROW); //加载鼠标样式
   wcApp.hbrBackground=(HBRUSH)(COLOR_WINDOW); //设置窗口背景色
   wcApp.lpszMenuName=NULL;
   if(!RegisterClassEx(&wcApp))    
   {
     MessageBox(NULL,"注册失败！","Hellowin ",0);
     return 0;
   }
 //设置窗口没有菜单
   HWND wnd=CreateWindowEx(0,"ss","ss",WS_OVERLAPPEDWINDOW,30,30,400,300,NULL,NULL,hInstance,NULL);
//   MessageBox(wnd,GetLastError(),"aa",MB_OK);
   if(!wnd)
   MessageBox(wnd,TEXT("咋就出错了捏"),TEXT("出错了"),MB_OK|MB_ICONQUESTION);
   ShowWindow(wnd,SW_SHOWNORMAL);
   UpdateWindow(wnd);

   while(true)
   {
      PeekMessage(&msg,wnd,0,0,PM_REMOVE);
  TranslateMessage(&msg);
  DispatchMessage(&msg);
   }
   return true;
}

LRESULT CALLBACK WndProc(HWND hWnd,UINT message,WPARAM wParam,LPARAM lParam)
{
    switch(message)
{
case WM_PAINT:
HDC hDC;
PAINTSTRUCT ps;
BeginPaint(hWnd,&ps);
TextOut(hDC,0,0,"Yeah",strlen("Yeah"));
EndPaint(hWnd,&ps);
break;
default:
return DefWindowProc(hWnd,message,wParam,lParam);

}
return DefWindowProc(hWnd,message,wParam,lParam);
}
