Webbrowser - Click on elements of a website

Question

Hello, everybody!

Here’s the thing, I need to make my program click on an element. Here’s a photo to make it easier to understand: http://i.imgur.com/Uitnkvt.png

I’ve tried a lot of things, but nothing successful so far... I want the button pressed

My code is like this so far:

Dim PageElement1 As HtmlElementCollection = WebBrowser1.Document.All.GetElementsByName("")
    For Each CurElement1 As HtmlElement In PageElement1

        If (CurElement1.GetAttribute("classname") = "preferred-login facebook-login") Then

            CurElement1.InvokeMember("click")
            MsgBox("Deu Certo")
        End If

    Next

But the "click" doesn’t work... Well, if anyone can help... Thank you in advance!

Answer 1

You can get the element by the class and click on it without the need to iterate all page elements.

webBrowser1.FindElementByClassName("preferred-login facebook-login").Click();

Or using the By.Classname selector:

webBrowser1.FindElement(By.ClassName("preferred-login facebook-login")).Click();

Answer 2

Using the code:

WebBrowser1.Document.All.GetElementsByName("")

You’re taking all the elements from the page that has the name attribute of "". That is to say:

<div id="id" name="bobagem"></div> <!-- não encontrado -->
<div name=""></div> <!-- encontrado! -->
<div name="" id="id2"></div> <!-- encontrado! -->

Answer 3

I’ve been trying to solve the same dilemma that you faced, or still face, and luckily, by making a small modification to your code, I managed to click the button.

Note: I had to fill the GetElementsByName("COLOQUEI O NAME DO BOTÂO ALVO").

Note: I had to remove the If ..., and then it worked.

Dim PageElement1 As HtmlElementCollection = WebBrowser1.Document.All.GetElementsByName("COLOCAR O NAME DO BOTÃO ALVO")
For Each CurElement1 As HtmlElement In PageElement1

        CurElement1.InvokeMember("click")
        MsgBox("Deu Certo")

Next

This way it worked for me, I hope it will be useful to you. A hug and thank you.
