case WM_RBUTTONDOWN:
{
    HMENU hPopupMenu = CreatePopupMenu();
    InsertMenu(hPopupMenu,MF_BYPOSITION | MF_STRING,ID_CLOSE,(LPCWSTR)"Exit");
    InsertMenu(hPopupMenu,ID_EXIT,(LPCWSTR)"Play");
    SetForegroundWindow(hWnd);
    TrackPopupMenu(hPopupMenu,TPM_BOTTOMALIGN | TPM_LEFTALIGN,hWnd,NULL);
}

但我总是得到如下所示的上下文菜单

我希望文本退出和播放显示在菜单中
