Copy Code
// The code fragment below shows how to use ON_COMMAND_RANGE macro
// to map a contiguous range of command IDs to a single message
// handler function (i.e. OnFileMenuItems() is the sample below). In
// addition, it also shows how to use CheckMenuRadioItem() to check a
// selected menu item and makes it a radio item.
BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
// ...
ON_COMMAND_RANGE(ID_FILE_MENUITEM1, ID_FILE_MENUITEM3, OnFileMenuItems)
END_MESSAGE_MAP()
void CMainFrame::OnFileMenuItems(UINT nID)
{
CMenu* mmenu = GetMenu();
CMenu* submenu = mmenu->GetSubMenu(0);
submenu->CheckMenuRadioItem(ID_FILE_MENUITEM1, ID_FILE_MENUITEM3,
nID, MF_BYCOMMAND);
