    text
    copied!<p>I'm trying to use a .Net WebBrowser control to log into a website and aggregate some data for me. I'm also using a reference to MSHTML (but I don't care if your solution does or doesn't).</p> <p>When I visit a 'normal' website - I create an mshtml.HTMLDocument from the webBrowser's .documment. Then I create a mshtml.FormElement and a mshtml.HTMLInputElement using the name of the textbox I want. </p> <p>Then, I can set the value of the textBox.</p> <p>It looks something like this:</p> <pre><code> Dim myDoc1 As mshtml.HTMLIFrame = DirectCast(Me.WebBrowser.Document.DomDocument, mshtml.HTMLDocument) Dim myForm As mshtml.HTMLFormElement = DirectCast(myDoc1.forms.item(0), mshtml.HTMLFormElement) Dim myUserBox As mshtml.HTMLInputElement = DirectCast(myForm.item("user"), mshtml.HTMLFormElement) myUserBox.value = UserName </code></pre> <p>My problem is that on some websites the textbox I need to manipulate is contained inside of an IFRAME. An example would be <a href="https://servicing.capitalone.com/c1/login.aspx" rel="nofollow noreferrer">https://servicing.capitalone.com/c1/login.aspx</a></p> <p>If my program surfs to that site - it can't find a textbox for the Username - because there isn't one. There is only an IFRAME tag that has a URL of '<a href="https://login.capitalone.com/loginweb/login/login.do" rel="nofollow noreferrer">https://login.capitalone.com/loginweb/login/login.do</a>'</p> <p>If I surf directly to the login.do page - the website redirects me to an error page. </p> <p>How can I enter data into the UserName textbox in that IFRAME?</p>
