Question

Well, now i have a new problem.
Im writing code in C#

I want to save from textBoxName into group.txt file each time i enter string into textbox and click on save button. It should save at this order (if its possible to sort it like A-Z that would be great):


1. Petar Milutinovic
2. Ljiljana Milutinovic
3. Stefan Milutinovic
4. ... etc

I cant get it to work, i tried to use tehniques from my first question, and no solution yet 🙁

This is easy one i guess, but im still a beginer and i need this baddly…

Answer 1

Try to tackle this from a top-down approach. Write out what should happen, because it’s not obvious from your question.

Example:

1. User enters a value in a (single-line?) textbox
2. User clicks Save
3. One new line is appended to the end of a file, with the contents of the textbox in step 1

Note: each line is prefixed with a line number, in the form “X. Sample” where X is the line number and Sample is the text from the textbox.

Is the above accurate?

(If you just want to add a line to a text file, see http://msdn.microsoft.com/en-us/library/ms143356.aspx – File.AppendAllText(filename, myTextBox.Text + Environment.NewLine); may be what you want)
