[moose333]

Hi

Need help reading data from a file after a specific point.
I need to read the data from this file into a richtextbox after the [HRData] header.

This is the contents of the file I'm reading from.

I've got the file displaying in a richtextbox at the moment using this code.

private void button1_Click(object sender, EventArgs e)
        {
            

            string Chosen_File = "";

            openFile.Title = "Choose File";
            openFile.FileName = "";
            openFile.Filter = "HRM|*.hrm|Text Document|*.txt";
            openFile.ShowDialog();

            if (openFile.ShowDialog() != DialogResult.Cancel)
            {
                Chosen_File = openFile.FileName;
                richTextBox1.LoadFile(Chosen_File, RichTextBoxStreamType.PlainText);
            }

I just need to now show the data after the [HRData] header.
Any help would be great.

Hi,
You can use StreamReader to read rows, and the code will look like this:

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            List<string> list = GetDataFromFile();
            richTextBox1.Clear();

            foreach (string item in list)
                richTextBox1.AppendText(item + Environment.NewLine);
        }

        private List<string> GetDataFromFile()
        {
            List<string> list = new List<string>();
            string tag = "[HRData]";
            bool bGetText = false;
            string path = @"C:\1\test17.txt";
            using (StreamReader sr = new StreamReader(path))
            {
                string line;
                while ((line = sr.ReadLine()) != null)
                {
                    if (bGetText)
                        list.Add(line);
                    else if (line == tag)
                        bGetText = true;
                }
            }
            return list;
        }
    }

The problem is, especially if you want to show numbers in some kind of columns, a better idea would be to use a datagriview - to seperate numbers. This is just an idea.

Btw, jsut in case:
that you would wonder where to get File class (add a new namespace: System.IO).

Cheers for this info.

I was looking at doing a datagridview before but I have no knowledge of how to do it. Do you know of any online tutorials that I might be able to have a look at to help me?

hmm.. dgv is so huge control and there is really a lot to lear if you want to use it and understand its work.
