How to click Image button in website vb.net - vb.net

so i am trying to click a image button in website with HTML code:
<a onclick="trylogin()"><img class="loginButton" src="/student/resource/AWSEd_Resource/img/search-execute.png"></a>
i've tried:
Dim element As HtmlElement = (From el As HtmlElement In WebBrowser1.Document.GetElementsByTagName("a").Cast(Of HtmlElement).Where(Function(h) h.GetAttribute("onclick") = "trylogin()")).FirstOrDefault()
element.InvokeMember("click")
And:
WebBrowser1.Document.Forms(0).InvokeMember("loginButton")
This is image button

Try executing the script directly using HtmlDocument.InvokeScript():
WebBrowser1.Document.InvokeScript("trylogin")

The code I'm trying inside the event Document Completed of the Web Browser control is:
Dim HtmlCollec As HtmlElementCollection
HtmlCollec = WebBrowser1.Document.GetElementsByTagName("button")
For Each iElement As HtmlElement In HtmlCollec
If iElement.GetAttribute("id").Equals("myImageId44") Then
RichTextBox1.Text = iElement.ToString
End If
Next
but Im getting as output:
System.Windows.Forms.HtmlElement
How can I get it? Thanks

Click String That Runs Javascript

I am trying to click a string of text within a web browser control that runs some javascript, I am unsure how to click the text as the method I use for buttons does not work in this instance
Function Clk(WebBrowserID, ElementID)
WebBrowserID.Document.GetElementById(ElementID).InvokeMember("click")
Return "Clicked"
End Function
This is all that is visible to the client in regards to the clickable text
<div class="task-skip pure-g">
<div class="pure-u-1">
Next
</div>
</div>
I am completely lost on how to either click the text so that the javascript script runs or to invoke the script through code so the button does not need to be pressed, any help would be greatly appreciated.
The solution that I found and worked is as below hope this will help anyone else with the issue.
For Each Element As HtmlElement In Browser.Document.All
If Element.InnerText = "TEXT HERE" Then
Element.InvokeMember("click")
End If
Next
Return "RETURN VALUE"

VB.NET webbrowser click button

I know this question has been asked many times and I have tried quite a few and none work.
I have a WebBrowser and 1 button. When I click the form button it needs to invoke a click on the WebBrowser button.
I have tried
WebBrowser1.Document.All("start-button").InvokeMember("click")
WebBrowser1.Document.GetElementById("convert1").InvokeMember("Click")
For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("a")
If element.GetAttribute("id") = "convert1" Then
element.InvokeMember("click")
End If
Next
None of the above works.
Link to website
Code from the webpage source
<a class="start-button" href="javascript:;" id="convert1" onmouseover="changeImage(this, '');" onmouseout="changeImage(this, '');">
Start
<i class="fa fa-angle-right fa-5"></i>
</a>
Also the button on the WebBrowser, when I click it nothing happens for some reason.
Any help would be great.
Thanks

Clicking HTML button in vb.net

I have to click a HTML button programatically which is on the 3rd page of the website . The button is without id. It has just name type and value . The HTML code of the button is given below
<FORM NAME='form1' METHOD='post' action='/dflogin.php'><INPUT TYPE='hidden' NAME='txtId' value='E712050-15'><INPUT TYPE='hidden' NAME='txtassId' value='1'><INPUT TYPE='hidden' NAME='txtPsw' value='HH29'><INPUT TYPE='hidden' NAME='txtLog' value='0'><h6 align='right'><INPUT TYPE='SUBMIT' NAME='btnSub' value='Next' style='background-color:#009900; color:#fff;'></h6></FORM>
i am using the following code to click it
For Each webpageelement As HtmlElement In allButtons
If webpageelement.GetAttribute("value") = "Next" Then
webpageelement.InvokeMember("click")
End If
Next
But i cant able to click it . I am using the vb.net 2008 platform. Can anyone tell me the solution to click it?
I was having the same problem as you. The InvokeMember looks correct so I can only assume its not picking up the correct html element. Try refering to the element explicitly using the value. The following code worked for me but I have adapted it for you:
For Each webpageelement As HtmlElement In allButtons
If webpageelement.GetAttribute("value").Equals("E712050-15") Then
webpageelement.InvokeMember("click")
Exit For
End If
Next
Good Luck :)
