VB6.0 "Do Not Call" help

Here is my dilema. I work for a company that has a marketing department set up in the back and we have run into a problem. Because of the new "Do Not Call" list that went into effect across the U.S., there are people that our marketing department can no longer call. I need to figure out a way to do the following:

1. Read in a standardized .csv file that contains the following fields: (AreaCode, PhoneNumber, FirstName, LastName, StreetNumber, StreetDirection, Street, City, State, ZipCode).

2. Compare the AreaCode & PhoneNumber fields to a MS Access database containing only a single field (DNCPhone) and output each record where the AreaCode & PhoneNumber do not match any DNCPhone field in the other database, giving a "Do Not Call" free list of people for the marketers to call. (The file to be checked has area code and phone number as seperate fields, but the Do Not Call list database is a 10-digit format from the Government.)

Here is the problem. I'm an extreme beginner using VB6.0, and do not know databases well. I wrote a scrubbing program that inputted the .txt files and compared them, but when dealing with a list of over 1 Million Do Not Call entries, it was very slow and unpredictable.

Is there some simple step I'm missing that will allow me to do this easily within a database, or any advice anyone can give me on this little problem?

I recomment u to read the cvs file use excel object and import it into the ms sql DB or ms access(do it in order to strore the data and query the data).And then compare the AreaCode & PhoneNumber data you imported and a MS Access database containing only a single field..It's easy to do after u do the import work.

I think u will visit some vb&DB tutorial,if u have little knowledge about the vb & DB develope(http://www.garybeene.com/vb/tut-db.htm)..
