Testing the Width of an Array

[Fordian-Slip]

Hi Folks -

I would like to know if there is someway to test for the existence of a column index within a particular array.

While trying to control memory managment, extensive number of array fields, etc... I am trying to figure out a way to test the existence of a column within an array.

The array is generated in stages, but there is one point that I need to test to see if a column has been created yet.
IsDefined and StructKeyExists doesn't seem to do the trick.

Any ideas?

Thanks,

Doug

In a CFTRY / CFCATCH block, attempt to read the array element. If it does not exist, you will throw an error, which can be processed in the CFCATCH block.

Thanks for the info.

That's what I figured it was (Try/Catch), but I was hoping I was missing a simpler answer.

Take it easy,

Doug
