What the IOleClientSite site does and what role it plays in ActiveX controls

After reading for a long time, I haven't figured out this concept!

However a container decides to provide storage elements, it will also need some sort of data structure or internal C ++ object to manage that storage and all the other information about the content object itself. This structure or object is called a client site, or container site . For every content object in a compound document, the container creates a site to manage that content object. The site itself also exposes container-side functionality to the content object in question through two interfaces of its own: IOleClientSite and IAdviseSink, as illustrated in Figure ...

... manage that storage and all the other information ...
I'm sorry, I still don't understand.

This interface is an excuse that must be inherited when your control needs inplace edit

Also encountered this problem
Borrow to ask, the DLL control I wrote originally did not have the IOleClientSite interface, but later because I needed to access the JAVASCRIPT function on the web page, so I added it, and then my control can not be registered when it is downloaded, but manually use regsvr32 You can register, why is this?

Files cannot be registered when they are downloaded

This may be the consideration of ie security. May need to implement other interfaces ISafe ****

It was downloadable before, but only after adding the IOleClientSite interface, it could not be registered, and I must have implemented the security interface and anything. It is really strange, why?

msdn: IOleObject :: SetClientSite
 The NULL pointer says that that no client site is available and thereby defers notifying the object handler of the client site until the object is initialized.

You can use GetClientSite () to try to get a site,
If it doesn't work, I don't know how to get a ClientSite,
I also did not find which default implementation ClientSite
