asptoday_discuss thread: Finding the number of elements in an array.

I am trying to create a shopping cart. I used the dictionary object
to store the Item and Qty. I want to loop through the dicObject and load
the results into an array. The problem is I don't know how many items
will be in the dicObject so I can set a fized lenght for the array. But
if I set the length of the array to something stupid like 500. I get 495+
empty records in my database when I dump the array back to it. I have
found comments on UBound but that doesnt seem to help me. Any ideas on
how to solve this problem?
thanks!

Mark,
The dictionary object has a count property that you can use to set the size
of your array.
Dim arrayName(dicObject.count -1)
I think you need to subtract one to avoid having an extra empty element .
The array is zero based and the count property is not.

That did the trick.
Thanks!
