The name capture does not exist in the current context ERROR

Question

Hi I am developing a campera capture application. I am currently using EmguCV 2.0. I get an error with the following line of code :

---

Image image = capture.QueryFrame();

---

I have added all the required references of EmguCV like Emgu.CV,Emgu.CV.UI, Emgu.CV.ML, Emgu.Util, but still it gives a error saying :

Error 1 The name 'capture' does not exist in the current context C:\Documents and Settings\TLNA\my documents\visual studio 2010\Projects\webcamcapture\webcamcapture\Form1.cs 27 38 webcamcapture

---

I got this code from here. The full program code is given below:-

---

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 Emgu.CV;

using Emgu.CV.UI;

using Emgu.CV.Structure;

using Emgu.CV.ML;



namespace webcamcapture
{
public partial class Form1 : Form
{


    public Form1()
    {
        InitializeComponent();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        Image<Bgr, Byte> image = capture.QueryFrame();

        pictureBox1.Image = image.ToBitmap(pictureBox1.Width, pictureBox1.Height);
    }




}
}

Looks like you forgot to declare a variable for capture.

Edit: never having used emgu myself, i cant help much, but a couple mins on google and i stumbled across http://www.emgu.com/wiki/index.php/Tutorial#Examples which might help you set up the capture object properly.
