win32 listctrl控件右键菜单的实现

HMENU Menu_list,Menu_all;
POINT point;
HINSTANCE hInstance;
//下面代码放到BOOL WINAPI DialogProc下
case WM_CONTEXTMENU:
            if((HWND)wParam == GetDlgItem(hWnd,IDC_LIST_VIEW))
            {
                Menu_all=GetSubMenu(Menu_list,);
                GetCursorPos(&point);//得到鼠标当前坐标，
                TrackPopupMenu(Menu_all,TPM_LEFTBUTTON,point.x,point.y,,hWnd,NULL);
            }
            break;
//下面的代码放到void OnCommand函数里
        case ID_CLA:
            SendMessage(hWndlist, LVM_DELETEALLITEMS, , );
            i=;
            break;
        case ID_DEL:
            {
                LVITEM item;
                item.iItem = SendMessage(hWndlist, LVM_GETNEXTITEM, -, LVNI_SELECTED);
                SendMessage(hWndlist,LVM_DELETEITEM,item.iItem,);
                i--;
            }
            break;

插入一个菜单资源，上面代码中有两个菜单项ID_CLA和ID_DEL。
