Okay I'm here with a question about a form I'm creating. It's a simple form that reads in the input from text boxes. I should be able to enter the text, and press my enter button to display it in the display box. I should also be able to save what it is displaying. When I click enter, it displays the information correctly. When I click save as, it adds two duplicates(a total of 3 lines of the information) to the text file. Where am I going wrong? I thought that the butten events would control this for me. I'm also needing to disable the enter box when there's no text in the fields, but that's not what I'm worried about right now, I'm more concerned about the part that's already coded and not working the way I thought it would.

        lstRecords.Items.Add(lastName.Text + "\t" + firstName.Text + (":") + "\t" + idBox.Text + "\t" + classBox.Text + "\t" + gradeBox.Text);
    }

I jumped the gun too quick I guess, I think I have it figured out, I had to move a button event up and it seemed to take off one of the duplicates. The other duplicate I know I'll have to have an if statement or something like that to stop it from doing that. Thanks for looking.

Okay, so I guess I'm still having issues displaying in the text box when I click enter. It shows nothing and I've tried to use
lstRecords.Text = string.Format(lastName.Text + "\t" + firstName.Text + (":") + "\t" + idBox.Text + "\t" + classBox.Text + "\t" + gradeBox.Text);
and I've also tried using the same code that i use for the save box to display it lstRecords.Items.Add(lastName.Text + "\t"+ firstName.Text+(":") + "\t" + idBox.Text + "\t" + classBox.Text + "\t" + gradeBox.Text); but I think that may have been my original problem. I'm trying to get the program to enter entries into the box with enter, then save using save as without doubling up. Any hints, ideas or comments would be helpful.

Okay, I'm seeing my main issue I think now, it's set up for csv, not individual textboxes, I wasn't taught how to do that. I'm going to go do some more reading.

I think I've found my information. When I complete my file I'll be happy to share what I have. Have a good day.
