Search in a .txt file, compare output and retrieve answer in collor botton
and text

Good afternoon,
I am trying to write and application to, using a txt file as data base,
compare results from the database to the ones inserted by the user
as an example.
The content of the text file would be:
Name Number Version Comment
Test1 001 1 Hello
Test1 001 2 Hello To all
Test2 002 1 Hi
Introducing the 001 and 1 on the program, it should pop you a red screen
with a small comment like "incorrect". introducing the 001 2 it should pop
a green screen, with a comment like OK.
Any idea in how to do it? Thanks in advance
