Array question

[HLong]

I have an array defined as Dim cLengths() as long. How
could I test to see if the array is not empty. When I try

For I=0 to Ubound(cLengths)
.......
Next I

It gives me an error if it is empty.

cLengths.GetUpperBounds()

HLong,

I never use that Ubound

I use forever in an inedexed loop for an array or a collection

for i as integer = 0 to array.length - 1 or collection.count -1
.....................
Next

I hope this helps,

Cor

This won't solve the problem. Still, a 'NullReferenceException' is thrown
if the array variable doesn't point to an array object. Consequently you'll
have to check if an array has been assigned prior to iterating over the
array's items and determining its length:

\\\
If IsArray(Lengths) Then
...
End If
///

- or -

\\\
If Not Lengths Is Nothing Then
...
End If
///
