CSV file based on timer event

[mprice214]

This works, but it seems a bit flakey. Also, does anyone know how to limit the file size?

using (StreamWriter writer = new StreamWriter("C:\\log.csv", true)) //add ,true to this to append
{
writer.WriteLine(textBox1.Text + "," + System.DateTime.Now);

        }

Define "flakey". Remember, a Timer is only one way to go. You could also use a background thread. In this case, be sure to handle concurrent access of UI (and other) data. /ravi

is it? I wasn't aware, I haven't seen one for ages. I am a model railroad enthusiast myself (N gauge, i.e. scale 1:160). :)

Great. The very first image[^] I looked at has a bill board for a shop in Ghent that is still there; I have bought some locs there once. Normally I go shopping in Germany... :) PS: may I suggest you add some navigation to your catalogs, moving to the next/previous page would increase the "user experience".

Sounds like you are doing some profiling/tracing. Google those terms, perhaps in combination with "C#" and anything more specific you are interested in. Or do as others say and create a timer that appends to the CSV file.

Hi boy, try this. :)

using System;
using System.Windows.Forms;
using System.IO;

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

        private void button1_Click(object sender, EventArgs e)
        {
            this.timer1.Enabled = !this.timer1.Enabled;
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            FileStream fs = new FileStream("test.csv",  FileMode.Append, FileAccess.Write);
            StreamWriter sw = new StreamWriter(fs);
            sw.WriteLine(DateTime.Now.ToString());
            sw.Close();
            fs.Close();
        }
    }
}
