vrf Dataset field size problem

So, in that field, my records will =
have 50 values instead of the 150 values with which the dataset was =
initially designed.

If you poke around a dataset you'll note that there is exactly ONE
record defnition. Hence all records in the dataset must be identical.

You'll need to put in dummy data or whatnot

This is exactly why I abandoned using records and datasets. Too many times, I set up a data logging structure, only to have someone request a new test to be added, or the data to be presented in a new way. Also, it forces you to write (and maintain/modify) the data extraction program as well. I write all my test data to text files now, so it can be pulled into excel, word, or whatever other program the end user feels like using. I haven't dabbled into writing to excel thru ActiveX yet, as I don't have the time to figure this out, but it seems to be the way to go now (assuming you only want to view the data in excel).

BTW, has anyone tried the Vxl add-in mentioned by Greg Wale from PassTechnologies? This sounds like it would save me the time (and headaches, judging by the percentage of vrf traffic dedicated to this) to learn how to do this myself.
