c++ - 错误 C2065：“MIIM_STRING”：未声明的标识符

Question

在尝试使用 InsertMenuItem 创建子菜单的菜单时：

MENUITEMINFO mii = { sizeof(MENUITEMINFO) };

mii.fMask = MIIM_SUBMENU | MIIM_STRING | MIIM_ID;
mii.wID = uCmdID++;
mii.hSubMenu = hSubmenu;
mii.dwTypeData =  _T("Net&Work Drive Solution");


// InsertMenu ( hmenu, uMenuIndex, MF_BYPOSITION | MF_POPUP, 
            // (UINT_PTR) hSubmenu, _T("NetWork Drive Solution") );

InsertMenuItem ( hmenu, uMenuIndex, TRUE, &mii );

我收到错误 C2065：“MIIM_STRING”：未声明的标识符

Answer 1

您必须定义WINVER为至少 0x0500。 MIIM_STRING定义如下：

#if(WINVER >= 0x0500)
#define MIIM_STRING      0x00000040
