win32 写的程序，加入了资源菜单，可运行是没有菜单显示。大侠帮忙！
同过加入 resource script 添加的菜单资源，可运行是没有菜单显示，小的实在找不到原因，求大侠帮忙：感激涕零！

.c文件如下：
# include <windows.h>
# include "resource.h "

[解决办法]
wndclass.lpszMenuName = MAKEINTRESOURCE(ABOUT2);
[解决办法]
1、wndclass.lpszMenuName = (LPCTSTR)ABOUT2; //需与你资源文件中菜单定义的部分相对应
2、有可能你没把rc文件加到工程里。
[解决办法]

if (DialogBox(hInstance,TEXT( "AboutBox "),hwnd,AboutDlgProc))=====> >

if (DialogBox(hInstance,MAKEINTRESOURCE(ABOUTBOX),hwnd,AboutDlgProc))
