I m working on this project where i need to get user input and then see if the user input is correct or not. if it is correct then show the user input in the label but if the user input is wrong then show user a warning message. now i got the text field, button and label working for right now whenever user input any thing in the text field it just shows the user input in the label. so now i want to add that extra feature to my program which is when ever user input anything my program needs to compare the user input to the file which I got. now i have to compare user input and compare with the file i got and then show the error message if it is wrong. so i m having problem to link to that file and how can i compare user input through that file and based on that file give user a right message. Any help please.
