Hi!The class BaseBitmapLink and BaseLink returns NULL if the object is not alive when deleted. I have a hook in ToolData which returns a SubDialog in 'AllocSubDialog' where Cinema 4D takes the ownership.
Is a class avaible which returns NULL if the Dialog was deleted?
Cheers,
Shawni

Hi!
Sure, I wanted to write, but I forgot in hectic. I wrote my own class like BaseLink, BaseBitmapLink.

I don't know if its the best way, but for me it works. If you hae any questions, critics or comments, please let me know.
