    Testing to see if a collection is initialized

    OK. So I haven't played with VB in a few years. And it shows. Bah.

    I've got a function that is passed a collection as an optional argument. I need to test whether or not that collection was initialized. Unfortunately, isEmpty only returns valid data for variants. In my mind, this should be fairly easy to do... but it escapes me at the moment. Any help would be appreciated.

    BTW, I'm using the Office 97 version of VB, if it matters. It was what was available.

    Thanks,

    DAlexander

    It depends what you mean by initialized. Every collection has a Count property and a Count of 0 means of course that it's empty.
