我用资源脚本添加一些菜单项怎么运行后窗口不显示相关菜单呢？

[解决办法]
估计里面有个 #define ID_MENU1 101
也或还有 #define MENUDOME 102

把这两句删除掉，试试
[解决办法]
如果要设菜单为MENUDEMO.
wndclass.lpszMenuName = "MENODEMO";

再在resource.h里面去掉#define MENODEMO 101 这个

确定你的资源rc 文件中是
// Menu
//前面一个名字是
MENUDEMO MENU DISCARDABLE

BEGIN

POPUP "&File"

BEGIN

MENUITEM "&New", IDM_FILE_NEW

MENUITEM "&Open", IDM_FILE_OPEN

MENUITEM "&Save", IDM_FILE_SAVE

MENUITEM "Save &As...", IDM_FILE_SAVE_AS
...........


更简单的可以这样做,如果你建一个菜单标识为IDR_MENU1.

wndclass.lpszMenuName = MAKEINTRESOURCE(IDR_MENU1);
