Access or VB.Net

Bon soir mes ami!

I have a quandary I'm hoping someone may be able to help with. I need to be able to produce a form with a drop down list of options that will search an excel spreadsheet for those specific details, which in turn will produce another drop down list of options relative to the first list... with me so far?!!

Now, I've attached an image of the top section of the form for your perusal. In essence it is for me to search a manufacturers name, to then see what appliances they offer, to then see what Makes, then Models, to parts listed against that model and finally to see how many of those parts are in my stock.

In your opinion, should I be using Access or VB.Net? And any pointers on code for either would be brilliant!

To me it isn't a question of either or.

Access is a database. VB.NET is a programming language.

Use both.

But I've seen an Access database with a graphical fascia with drop down list selections - why would I need to use both when they can do it on their own?
