Checking the number of the data of the added property of Array type user

We use the method called [PropertyValueCount]
in the rootobject to check the numbers.

For example use VB to set it as follows
Dim propID As Long
Dim numData As Long

propID = root.LookupPropID(“OrderUser_TEST”)
numData = root.PropertyValueCount(order, propID)

※root is ASORootObject、and the order is ASBOrder. Get it from argList first.
※LookupPropID is the method to get the ID of the property. See here about the LookupPropID.
