Win32汇编菜鸟求助有关显示窗口菜单的问题！！！
小弟最近在学习Win32汇编，看的是CHM版Iczelion的Win32汇编教程，我把菜单教程例子复制到MasmPlus中编译运行，结果运行后只显示了个空白的窗口，没有菜单，求指教。ASM文件代码：
.386
.model flat,stdcall
option casemap:none
WinMain proto :DWORD,:DWORD,:DWORD,:DWORD
include windows.inc
include user32.inc
include kernel32.inc
includelib user32.lib
includelib kernel32.lib
.data
ClassName db "SimpleWinClass",0
AppName db "Our First Window",0
MenuName db "FirstMenu",0 ; The name of our menu in the resource file.
Test_string db "You selected Test menu item",0
Hello_string db "Hello, my friend",0
Goodbye_string db "See you again, bye",0
.data?
hInstance HINSTANCE ?
CommandLine LPSTR ?
.const
IDM_TEST equ 1 ; Menu IDs
IDM_HELLO equ 2
IDM_GOODBYE equ 3
IDM_EXIT equ 4
