Stop Duplicates

[rosshstarr]

First off, good simple to follow code. Really great to see code a beginner can follow - thanks.
My question regards insert data into the database, how exactly do you stop duplicates from being added to the table?
Probably a stupid question, but I'm brand new to this coding lark. :o)

Hi there, welcome to VB.NET! It's a great language, so you've made a good pick. In case you might be interested, a few of us have formed a small rag-tag community over on Discord: https://discord.gg/yVGSvt9E. We'd love to see you there.

To your question (a good one)... have a look here: https://stackoverflow.com/a/3635038

Holler if that all seems a bit complicated, and I'll try to break it down a little better. (Note that I'm not affiliated with this repo nor the article—I'm just someone out here slogging through the code like everyone else.)
