title: Refresh or Redraw picturebox in VB.net
body: <p>I'm trying to view youtube captcha in my vb application but I don't know how to refresh/redraw the picture box. The youtube captcha is in <a href="http://www.youtube.com/cimg" rel="nofollow">http://www.youtube.com/cimg</a> and the captcha is changing everytime I refresh the page. How can I do that using button or timer in vb.net to change the captcha. Here is the code I used to load the captcha to picturebox.</p>
  
  <pre><code>    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
          captchaBox.ImageLocation = "http://www.youtube.com/cimg" 
      End Sub
  </code></pre>
  
  <p>i try to use captchaBox.Refresh() but it's not working. I hope someone can help me. thx</p>
