How to check if DB.***DictionaryId is valid?

Bradleywalker12380 — Tue, 11 Jan 2022 07:14:46 GMT

When getting the ObjectID for a specified dictionary (Example: db.DataLinkDictionaryId, is there a way to make sure its a valid (exists in the drawing) before trying to use it and getting an exception?

I tested this:

... Dim imageDictId As ObjectId = RasterImageDef.GetImageDictionary(oDb) If imageDictId.ToString <> 0 Then ' Proceed ...

Which that code does work, but is there a better way of doing it?

Thanks!
