[CS3] How to get whether a UID is a spread, page, page item?

Hello!

I have a database.

database->GetClass(myUID) workes!

Thanks!

You can't.

If you have a database for that UID though, you can use database->GetClass(myUID) ...

Rather than dispatching on the class ID, you better identify your required interfaces on the boss. Instantiate them (again using db+id) and if those do not exist navigate around in IHierarchy or give up gracefully. Note there are some more boss classes and stranger arrangements than you initially know - master spreads, groups, standoff, inline items, multicolumn text and so forth.
