关于播放列表循环播放的算法


  ListOneCurOldIndex = ListOneCurIndex;
  ListOneCurIndex++;//当前播放的文件索引           if(ListOneCurIndex >= ListInfo_One.GetSize())
  {
                 for(i=0;i<ListInfo_One.GetSize();i++)
        {
                    strPath = ListInfo_One.GetStringtAt(i);//从播放列表的链表中取文件路径
                    if(pThis->IsFileExist(strPath))//判断该路径是否存在
 {
      ListOneCurIndex = i;
                              break;
 }
        }
                 if(i==ListInfo_One.GetSize())//如果遍历整个文件链表，列表中存在的文件都不存在
       {
                          pThis->m_Edit_FlieName_One.SetWindowText("无文件发送");//显示播放参数

      }我是这样处理的，这样处理很笨，大家有更好的吗，建议下：
