Progress Bar That Changes Text And Pictures

开发者_StackOverflow中文版I am making a project in C#. I am trying to get a label and a picture to change when the progress bar reaches a certain point. The step is 10 and the maximum is 5000. So far I have this

private void button3_Click(object sender, EventArgs e)
{
    timer1.Start();
    pictureBox2.Enabled = true;
    pictureBox2.Visible = true;
    label1.Text = "Scanning";

    this.pictureBox4.Enabled = true;
    this.pictureBox4.Visible = true;
    this.pictureBox3.Enabled = false;
    this.pictureBox3.Visible = false;
    label1.Text = "Threat Detected";

    // ...

What I am trying to do is when it reaches 500, for the picture to change and the label to change also.

The easiest way would be to use a System.Windows.Forms.Timer component, and handle the Timer.Tick event:

    private void timer1_Tick(object sender, EventArgs e)
    {
        progressBar1.PerformStep();

        if (progressBar1.Value == 500)
        {
            // do whatever you want
        }
    }
