如何在VB中单击此按钮？

Question

This is the button element:

<input type="image" class="btnClaim" src="http://cdn1.swagbucks.com/content/results/images/btnClaimPrize.png" onclick="sb_vd.capSubmit();">

I've tried this code:

 Dim allelements As HtmlElementCollection = WebBrowser1.Document.All
                        For Each element As HtmlElement In allelements
                            If element.GetAttribute("class") = "btnClaim" Then
                                element.InvokeMember("click")

but it does not click the button. How do I programmatically click this button?

Answer 1

It is possible with javascript

  window.onload=function()
  {
   img_click();
  }
  function img_click()
  {
    //do the code
  }
