单击WebBrowser控件vb.net中的按钮(Click button in WebBrowser control vb.net)

 我想点击下图中突出显示的按钮。 代码来自网页： 
 
  
 
 我不确定，但我相信按钮是在iFrame中。 
 
 我努力了： 
 
Dim wrapClick As HtmlElement = Contact.WebBrowser1.Document.GetElementById("Btn_WrapUp")
wrapClick.InvokeMember("Click")
 
 和： 
 
Dim elPoint As New Point(704, 340)
Dim wrapClick As HtmlElement = Contact.WebBrowser1.Document.GetElementFromPoint(elPoint)
wrapClick.InvokeMember("onClick")
 
 和： 
 
Contact.WebBrowser1.Document.GetElementById("Btn_WrapUp").InvokeMember("Click")
 
 在上面的所有内容中，我尝试过'onClick'和'Click'。 
 
 WebBrowser1采用不同的形式。 
 
 谢谢！ 

I am trying to click the button highlighted in picture below. The code is from a web page:
 
 
I'm not to sure, but I believe the button is within an iFrame.
 
I have tried:
 
Dim wrapClick As HtmlElement = Contact.WebBrowser1.Document.GetElementById("Btn_WrapUp")
wrapClick.InvokeMember("Click")
 
And:
 
Dim elPoint As New Point(704, 340)
Dim wrapClick As HtmlElement = Contact.WebBrowser1.Document.GetElementFromPoint(elPoint)
wrapClick.InvokeMember("onClick")
 
And:
 
Contact.WebBrowser1.Document.GetElementById("Btn_WrapUp").InvokeMember("Click")
 
In all of the above, I have tried 'onClick' and 'Click'.
 
WebBrowser1 is on a different form.
 
Thanks!
