error C2065: 'MIIM_STRING' : undeclared identifier

While Trying to create a Menu to SubMenu using InsertMenuItem:

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("N开发者_运维知识库etWork Drive Solution") );

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

I am getting error C2065: 'MIIM_STRING' : undeclared identifier

You must define WINVER to be at least 0x0500. MIIM_STRING is defined like this:

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