Adding UDT to a Collection


New Member
Hi all

When I try to add a UDT (defined using public type in the declarations section of a module) to a collection I get a compile error along the lines of 'Only user-defined types defined in a public object module can be coerced to or from...'. Am I doing something wrong or is it just that user-defined types cannot be added to a collection at all? Sorry if I'm repeating a previous post, I searched for a while and couldn't find anything.

You can't add UDTs to a Collection as far as I know. If you need a Collection, you'll need a class instead; otherwise you could use an array?

Hi Rory

I'd figured it just wasn't possible, thanks, and I'll be fine with an array, I just have to be a bit more careful!!

Thanks for the speedy reply
