GetElementById isn't working on certain boxes - vb.net

I'm trying to make an automatic login in my program.
This is the code I'm using to find the email box and then set the value:
WebBrowser1.Document.GetElementById("email").SetAttribute("value,", ID & "#hotmail.com")
If I insect the element of the email box it says input class="textbox" type="email" name="email"
What am I doing wrong? :L

The element doesn't necessarily have to have an ID.

If that's the case, you should take a look at getting a collection via GetElementsByTagName and looping through - something along these lines:
Dim Elems As HtmlElementCollection
Elems = WebBrowser1.Document.GetElementsByTagName("input")
For Each elem As HtmlElement In Elems
Dim nameValue As String = elem.GetAttribute("name")
If nameValue.ToLower().Equals("email") Then
elem.SetAttribute("value,", ID & "#hotmail.com")
End If
Next

Refer to id instead of name. i.e. "email_ema" instead of "email"
input name="email" type="button" id="email_ema" value="+" style="display:None;"...
WebBrowser1.Document.GetElementById("email_ema").SetAttribute("value,", ID & "#hotmail.com")

GetElementById Two same ID's

Hey I need help well im trying to make a program that uses a site to do some stuff and it has two of the same id's for both textboxs im trying to input into my code is WebBrowser2.Document.GetElementById("form-control-3").InnerText = BunifuMaterialTextbox1.Text. Well anyway im tryint to do that to input into the first textbox and the 2nd textbox has the same id and classname so i don't really know what to do.
You could try grabbing all the HTML elements based on the tag and then loop through to see if the id matched. Something like...
Dim Elems As HtmlElementCollection
Elems = WebBrowser2.Document.GetElementsByTagName("[tagName]")
For Each elem as HtmlElement in Elems
Dim idStr As String = elem.GetAttribute("id")
If ((idStr IsNot Nothing) And (idStr = "form-control-3"))
elem.InnerText = BunifuMaterialTextbox1.Text
End If
Next
i don't know if this help but you can do a input array
example:
<input name="name[]">
and...
document.getElementsByName("name[]")

Get value of input in vb.net webbrowser?

I have the following input, I want to get it value using vb.net WebBrowser, and then put it into a variable how can i perform that?
<input type="hidden" name="loginurl" value="https://example.com?ctoken=KWYZlCrYxt">
I'm trying to use this code, but i don't know how to put the value i got into a variable:
For Each Element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("input")
'Depending on how the source code is formatted on the tag, you may also try Element.OuterHTML, Element.InnerText and Element.OuterText in the line below
If Element.OuterHtml.Contains("name=""loginurl""") Then
Element.GetAttribute("value")
Dim login = value
WebBrowser1.Navigate(login)
Exit For
End If
Drag and drop webbrowser control and use the following snippet
WebBrowser1.Navigate("https://example.com?ctoken=KWYZlCrYxt")
Here is a good reference
Hope this is useful
I'd say just assign a variable with Dim attributeValue = Element.GetAttribute("value")... am I missing something obvious here?
For Each Element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("input")
'Depending on how the source code is formatted on the tag, you may also try Element.OuterHTML, Element.InnerText and Element.OuterText in the line below
If Element.OuterHtml.Contains("name=""loginurl""") Then
Dim attributeValue = Element.GetAttribute("value")
Dim login = value
WebBrowser1.Navigate(login)
Exit For
End If
Try:
Dim AllElementes As HtmlElementCollection = WebBrowser1.Document.All
For Each webpageelement As HtmlElement In AllElementes
If webpageelement.GetAttribute("name") = "loginurl" Then
Dim login = webpageelement.GetAttribute("value")
WebBrowser1.Navigate(login)
End If
Next
should work.

Pull webpage information to text box

So what I am trying to do is pull some data from a webpage, and put it into a text box. Online, I can find alot about doing it the other way around (putting text box into web) but none the way I want.
I have gotten this far... (not very) and have no clue where to go from here
Dim Helement As HtmlElement
Helement = WebBrowser1.Document.GetElementById("txtAddress1")
Helement.GetAttribute()
Here is the element from the browser I am trying to use
input#ctl00_m_g_79f90d63_a5eb_43e1_9403_69fefa0ba004_ctl00_txtAddress1
Thanks guys!
This is what I tried:
Dim Helement As HtmlElement = WebBrowser1.Document.GetElementById("txtAddress1")
Dim elementtype As String = Helement.GetAttribute("text")
Dim textContents As String = Helement.InnerText
Address.Text = textContents
The GetAttribute function will return the value of an attribute of the element you retrieved using GetElementById.
For example, something like:
<input type="text" id="txtAddress1">
Dim Helement as HtmlElement = WebBrowser1.Document.GetElementById("txtAddress1")
Dim elementType as String = Helement.GetAttribute("type")
Dim textContents as String = Helement.InnerText

Block a certain element in web browser Vb.net

I a wondering if and how you would be able to block a certain element in the webbrowser.
For example there is a certain element on a website:
<div class="btn" id="button" value="ClickMe"/>
Will you be able to block or hide that specific element in the webbrowser?
There might be a certain ad, iframe or whatever its called that might just be in the way?
Thanks for the help I appreciate it.
double click on webbrowser1 designer you should be in WebBrowser1_DocumentCompleted add this line
'selector by division id
webbrowser1.Document.getElementById("button").innerHtml = ""
'selector spesific element with spesific attribute
<input id="_authentication_token" name="_authentication_token" type="hidden" value="11740686"/>
dim mycol as htmlElementCollection = webbrowser1.document.getElementBytagname("input")
for each ele as Htmlelement in mycol
if (ele.getAttribute("value").tostring = "11740686") then ele.innerHtml = ""
next
for your exemple :
<div class="btn" id="button" value="ClickMe"/>
dim mycol as htmlElementCollection = webbrowser1.document.getElementBytagname("div")
for each ele as Htmlelement in mycol
if (ele.getAttribute("value").tostring = "ClickMe" and ele.getAttribute("id").tostring = "button" ) then ele.innerHtml = ""
next

How to select drop down value - Vb.net Webbrowser

I want to select a dropdown value with vb.net webbrowser
<OPTION value=1>One</OPTION>
<OPTION value=2>Two</OPTION>
The values 1 & 2 are without the quotes
If the value is within quotes such as value = "1"
Then I can use the code
WebBrowser1.Document.GetElementById("ID").SetAttribute("Value", "1")
But it does not work for the above.
Thanks in advance.
Actually it does not matter if there is a quote or not. I created test code and it seems to be working.
For Each Frame As HtmlWindow In currentWindow.Frames
Dim btnElementCollection As HtmlElementCollection =
Frame.Document.GetElementsByTagName("Select")
For Each curElement As HtmlElement In btnElementCollection
Dim controlName As String = curElement.GetAttribute("id").ToString
If controlName = TextBox2.Text Then
curElement.SetAttribute("Value", TextBox3.Text)
End If
Next
Next
TextBox2 is the id TextBox3 is the value
Sorry, not sure why it didn't work the first time and thanks for everyones time.
Try setting the attribute name to uppercase.
<OPTION VALUE=1>One</OPTION>
<OPTION VALUE=2>Two</OPTION>
Note "value" is now "VALUE"
You should set id of the target element.
This should be
GetElementById("ID")
this
GetElementById("element id ")
View your page source to get the correct id.
