CS4: Using custom data links

Hi all!

I've created my own database based datalinks using Adobe custom datalink example. It uses URI to get data stream from database.

There are several things I don't know how to do:

1. How to apply my link to image or text items? I can't use Adobe example because it uses kImportAndLoadPlaceGunCmdBoss and loads data from file but my datalink loads data from database. I found IDataLinkHelper::AddDataLink method but I didn't find any example with it so I'm not sure how to use it correctly.

2. How to remove my datalink? There is IDataLinkHelper::RemoveDataLink method but there are not any examples with it too.

Thanks in advance.
