 Hello again all.One of the objects in my plugin needs to store an array of other objects of a certain type in its container. I was looking at the sdk documentation and did not see any way of storing a BaseObject in a container. Is there some easy way to do this or do I need to do something like store the names of all the objects and search for them each time I need them? Thanks. Aaron M

Do I have to declare a variable of the type BaseLink such as this: BaseLink* o1=op.GetLink(); op being a BaseObject. The BaseLink can be an array also, correct? I haven't been able to understand much about Alloc() either. Does this apply here too? Thanks. Aaron M

It can store anything derived from this class (BaseObject, BaseTag, and so forth). There is also a GetObjectLink() variation which will return the pointed link as a BaseObject*. Otherwise, cast the returned pointer to the type being set: BaseTag* t1 = static_cast<BaseTag*>(op->GetDataInstance()->GetLink(ID_TAGLINK, baseDocument)); BaseObject doesn't have a GetLink() method (either declared or inherited). Most of the time, you get and set your BaseLinks through the object's BaseContainer (GetDataInstance() is one way to get to it) and requires a generic LONG ID value. No, the link is to a single instance of one of the classes mentioned above. One link per ID only. To store multiple objects, you will need multiple IDs.

If you use the BaseContainer->SetLink(), does the BaseObject need to be in the document as a requirement? The reason I ask is that I created a BaseObject, and only using it as a reference object, so I don't add it into the document. Would this be saved too with SetLink?

And there is no mention that it can be NULL.
