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.

I have a question, how to change HTML input value?
<select name="sys_lenght" aria-controls="systable" class>
<option value="20">Value 1</option>
<option value="40">Value 2</option>
<option value="80">Value 3</option>
</select>
I used this code
For Each Elementz In WebBrowser1.Document.GetElementsByTagName("select")
If Elementz.Name = "sys_lenght" Then
Elementz.setAttribute("value", "80")
End If
Next
But it doesn't change the input value, only the text "Value 3".
How can I solve this problem? Thanks
sys_lenght's value indicates which option with the specified value is selected. Thus if you set sys_lenght.value to "80" it will select Value 3.
To change the value of the currently selected option you have to get a reference to that first. You can do so by getting the selectedIndex of sys_lenght, and then get the specific item from that index.
For Each Elementz In WebBrowser1.Document.GetElementsByTagName("select")
If Elementz.Name = "sys_lenght" Then
'Get the index of the selected option.
Dim SelectedIndex As Integer = Integer.Parse(Elementz.GetAttribute("selectedIndex"))
If SelectedIndex >= 0 Then
'Get the option element from the resulting index.
Dim SelectedOption As HtmlElement = Elementz.Children(SelectedIndex)
SelectedOption.setAttribute("value", "80")
Else 'No option selected.
MessageBox.Show("No option selected!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
Exit For 'We found what we were looking for; stop looping.
End If
Next
First you have to understand how html open and close tag, you forgot to close the html selection option open tag i mean the last greter sign > then use javascript query to find the value within the option example
WebControl1.ExecuteJavascript('document.querySelector('option [value='your value']').selected=true;")
hope its help?
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[]")
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.
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")
I want to know how to put text to a website's textbox with VB.NET.
Like when you complete a textbox and press enter.
Something like this:
Dim web as webbrowser
web.document.textbox(1).insert("text")
it would look something like this:
WebBrowser1.Document.GetElementById("login_password").SetAttribute("value", TextBox2.Text)
As giuseppe has suggested, you need to search for the element in the document and then set it's value property. for example following code logins into website by setting its userId and password textboxes and clicking the submit button.
Dim htmlDoc=WebBrowser1.Document
Dim elem_Input_UsrName As HtmlElement = htmlDoc.GetElementById("username")
Dim elem_Input_PssWrd As HtmlElement = htmlDoc.GetElementById("password")
Dim elem_Input_Submit As HtmlElement = getElementByClassName("Submit", "Input", htmlDoc)
If elem_Input_UsrName IsNot Nothing AndAlso elem_Input_PssWrd IsNot Nothing Then
elem_Input_UsrName.SetAttribute("value", "xyz#ABC.com")
elem_Input_PssWrd.SetAttribute("value", "yourpassoword")
elem_Input_Submit.InvokeMember("click")
End If
This will help 100%:
webbrowser1.document.getElementById("yourtextboxidinwebsite").innertext = textbox1.text
I get a way that if u want to receive from the website itself another way I need to receive results from the website into the text box. U can use this method.
first, make a web browser to load the page
WebBrowser1.Navigate("https://tools.keycdn.com/geo")
then this
TextBox1.Text = WebBrowser1.Document.GetElementById("geoResult").InnerText
