Extracting a field from RESTORE HEADERONLY

I'm trying to use 'RESTORE HEADERONLY ' to get the date when the backup I'm about to restore was made. The command: RESTORE HEADERONLY FROM DISK = '' works fine in Query Analyzer and gives a resultset with something like 50 columns. The problem is actually accessing this from code. I can get this into a temp table by declaring every single one of the 50:ish columns, inserting into it with exec and getting the value I want from there. The problem is that I really want to avoid having to declare the entire resultset as a temp table as it seems like a very brittle solution if they ever add columns to it in future versions. Is there any way to just get a single column out of this resultset without declaring all the columns?
