Getting the time interval between typing characters in a TextBox, in C#
- by sama
I have a form that has a TextBox and a Label and I want to get the time of the first character entered in the textbox. Then if the user enters more than ten charcaters, the time between the first charcter entered and the tenth charcter entered is displayed in the label.
Can any one help me please? I'm using C#
Here is the code but I cannot complete it and I have many things that need to be written but I don't know how to continue.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Threading;
namespace n
{
public partial class Form1 : Form
{
int count=0;
public Form1()
{
InitializeComponent();
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
DateTime t1 = new DateTime();// the time when entering the first charcter
DateTime t2 = new DateTime();
t2 = System.DateTime.Now - t1;
int index = textBox1.SelectionStart;
Point p;
p = textBox1.GetPositionFromCharIndex(index);
Thread t = new Thread(counttext);
t.Start();
label1.Text = "t2";
}
private int counttext()
{
while (textBox1.Text.Length < 10)
{
count++;
if (count == 10)
return count;
}
}
}
}
