微软的Office的Word或Excel等文档都在一个文件中保存复杂有层次的情报,这就是CompoundDocument技术,就是在一个文件中有整个文件系统的功能,如子文件夹(Storage)和子文件(Stream),也有路径.为了方便操作CompoundDocument文件,我用ATL开发了个ActiveX控件(automation server),程序如下: 1. Card project have three parts: ZjjCardBase, ZjjDiaryCard and ZjjEncrypt. 2. 1999/4/1 a new DLL project named ZjjBookCard is created for dealing with the electronic book. And in this project I will try the function of EXCEPTION, CComQIPtr. 1999/4/10 the book card dll project is finished(include test), here is the project: 3. 1999/4/23, I begin to update the ZjjBookCard to version 1.1. In this version a new interface named IZjjBookCardChapters will be supported. And this new interface will implement the enumerator functions, so you can enum one chapter by one chapter(in VB, for each ... in ...). 1999/4/25, I find a strange problem that only the properties and methords defined in main interface will be exposed by the object's dispatch interface. That means the dispatch interface is only belongs to it's main interface, so I can't implement the enumerator functions now. Maybe there is some solution for this, but this time I will just halt it and attach the new zip file here for later studying. 4. 1999/7/16 I find something must be mentioned as important. That is when you call the GetStreamInfoIn or GetStorageInfoIn, you will get a failure if this stream or storage has been already opened. 5. 1999/7/17 Today I find a problem in the ZjjCardBase. The problem is that the m_liststream is incorrect after I add a new string(stream name) to it when I create a new stream. So everytime I add a new stream I will do "EnumStorage", and that will change the sequence of the storage and stream in the m_liststream and m_storagestream. So try not to use the GetStreamByIndex or GetStorageByIndex, and you can use the GetStreamByName or GetStorageByName.And I have checked the influence to the past project by this change, I found nothing is wrong. though in the ZjjDiary project, I have used the GetStorageByIndex after I create a new storage, but because I haven't call the "EnumStorage" after creating a new storage, so it is ok. Be careful that never do the change as calling the "EnumStorage" after creating a new storage in the future. 6. 1999/9/14: I resemble the project file and document file here: 文档:500)this.width=500'>_Doc.zip 加密:500)this.width=500'>_Encrypt.zip 基础COM:500)this.width=500'>_CardBase.zip 日记COM:500)this.width=500'>_CardDiary.zip 书类COM:500)this.width=500'>_CardBook.zip
