我想保存和读取RICHTEXT类的对象，但是当我使用下面的代码时，我不知道如何获得STREAMID,比如说：我从磁盘读取一个文件，并把其内容读入RICHTEXT中，我没法得到STREAM ID,我要怎么做才行？请高手们指点，万分感谢，

iRichTextEditor->RichText()->RestoreL(*theStore,streamId);

I guess what you need is that you want to store a rich text in a file, then your application is closed. After some time you use your application to open the file again. So your store is a permanent file store, it can be identified by the file name.
