Matching numbers !

i have a text field into which the user inputs a number up to 700, i also have a notepad file which contains numbers up to 700 and a special mesage written in front of them. example - 555: hello how are u ?
with a button click how do i show the corresponding message the user entered ?

That's too broad a question. Split your task into its component parts.
-- Do you know how to display a text field on screen?
-- Do you know how to retrieve its text?
-- Do you know how to display a button on screen, along with the text field?
-- Do you know how to respond to a button click?
-- Do you know how to read a file into memory?
-- Do you know how to compare Strings for complete and partial correspondence?
