Deleting rows based on date range that is parsed from file name

Hi,

I am (going to) writing an access macro to delete a range of dates that exist in

Table: Data
Field: TRIP-DATE

This date would be parsed from an excel file name that exists in a specific folder. I have the functions to check if a file exist in a folder, etc.

The file name would be "Nov 25, 2011 - Trip Data.xlsx"

In the above case, I want to delete all records from the table called "DATA" with the "TRIP-DATE" being in the range of 11/25/2011 to 11/06/2011 (Nov 6 or 21 days before or prior 3 weeks)

Let alone I have another problem of deleting all dates that comes within this range - not nessarily beginning and the end date (but thats aside)

How can I decode the above file name just to get the date portion and how would I delete the range? I am asking 2 questions because I've made some progress in delete portion; please let me know if the questions require 2 parts.

I am guessing the file name has to be put through an excel-like formula (eg: left(filename, 12)?)

I did some research and found this (the date is in text form so the quotes are added at the end)

rSQL = "delete * from Data WHERE TRIP-DATE = '" & Me.date & "'"

So I am guessing I would have to run the above code for each date (by looping?)
