Validation

[grey15]

Hi
I have asp.net page which stores info to text file. Now, i have to validate the data entered in the form to the info in the text file.e.g i have text field for first name, so i have to use first name and display message if that first name already exists in the text file.

I guess you are asking how to write this process. You will need to loop through your text file and search for the first name. If the name is found then break out of the loop and show an appropriate message. If the loop fully executes and the first name was not found then I assume you want to add it to the text file. I am sure there are many examples on how to do this so search for some examples and reply with a specific question if you get stuck on something.
