求各位帮忙

求各位大虾帮忙!
小弟初学win32编程,写了个大体框架:
#include <windows.h>

LRESULT   CALLBACK   WinProc(HWND   hwnd,             //   handle   to   window
    UINT   uMsg,             //   message   identifier
    WPARAM   wParam,     //   first   message   parameter
    LPARAM   lParam       //   second   message   parameter
);

int   WINAPI   WinMain(HINSTANCE   hInstance,
      HINSTANCE   hPrevInstance,
      LPSTR   lpCmdLine,
      int   cmdShow)
{
WNDCLASS   wndCls;
wndCls.style   =   CS_VREDRAW;
wndCls.cbClsExtra   =   0;
wndCls.cbWndExtra   =   0;
wndCls.hbrBackground   =   (HBRUSH)   GetStockObject(WHITE_BRUSH);
wndCls.hCursor   =   LoadCursor(   NULL,   IDC_CROSS   );
wndCls.hIcon   =   LoadIcon(   NULL,   IDI_APPLICATION   );
wndCls.hInstance   =   hInstance;
wndCls.lpszClassName   =   "ysjh ";
wndCls.lpszMenuName   =   NULL;
wndCls.lpfnWndProc   =   WinProc;

HWND   hWnd;
hWnd   =   CreateWindow(   "ysjh ",   "我的第一个win32程序 ",   WS_OVERLAPPEDWINDOW,0,   0,   600,   400   ,   NULL,   NULL,   hInstance,   NULL   );

RegisterClass(   &wndCls   );

ShowWindow(   hWnd,   SW_SHOWDEFAULT   );

UpdateWindow(   hWnd   );

MSG   msg;

while(   !GetMessage(   &msg,   NULL,   0   ,   0   )   )
{
TranslateMessage(   &msg   );
DispatchMessage(   &msg   );
}
return   msg.wParam;
}编译通过,却运行不起,不知道什么原因,希望大虾们帮帮忙,先谢过了!
