How do you tell how many elements are in an array, so 
that you don't encount the error: "Subscript Out of 
Range"?


Is there such a thing as:
For Each ELEMENT in ARRAYX NEXT?

or:
for counter = 0 to ARRAYX(MAX NUMBER) where maxnumber is 
specified in a function somewhere? 

Thanks.

Some objects have a ubound property

X =3D Obj.ubound

And for those that do not including arrays, use:

X =3D Ubound(arrayname)

Thanks,

Chris Thompson

If you are dynamically populating an array using ReDims or have a fixed 
size array, then you can use UBound, otherwise  you'll have to use a 
variable as a value.

I am using the Split Function. LIke this:

SKUs = Split(SKULog,"|")

Now I need to know how many SKUs there were, and if I 
try and reference an array element that does not exist, 
I get the error.

This will do it

Dim X as long
X =3D Ubound(SKUs)

I believe if you have a 10 space array meaning array(0) - array(9)
That it will return 10, but it could be 9.  Check to make sure.
Thanks,

Chris Thompson

Check the UBound() of the resulting array first.

<%
arrSKUs = Split(SKULog,"|")

If isArray(arrSKUs) then

    For i = 0 to UBound(arrSKUs)

        Response.Write(arrSKUs(i) & "<br>" & vbCrLf)

    Next

Else

    Response.Write("No array!")
    
End If
%>
