input data to website

• R.Tutus

  it's a tricky one really since you need to know what the page has in terms of elements and its names etc...

  once you get hold of an element, just set its innerText property then submit it or whatever so it can go ahead and process it.

  Example, I wanted to look for an element called "txtSearch" in the current document.

   

  HtmlElement theElement = this.theWebBrowserControl.Document.GetElementById("txtSearch");

  if (theElement != null)

  {

     theElement.InnerText = "hi!"; //sets the text inside this control

  }

  ok what would I do to find the text in this box.
  

  <input name=hostName size=15 maxLength=39 value='banished' style=font-family: Arial; font-size: 10pt>(Required by some ISPs)</font></td></tr><tr><th align=right width=186 bgcolor=#000000><font face=arial color=#FFFFFF size=2>Domain Name :&nbsp;</font></th><td width=559>&nbsp;&nbsp;&nbsp;<font face=arial size=2>
  
  
  the name is hostName so I tried but it didnt show anything.
  
  
  

  private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
  {
  HtmlElement es = webBrowser1.Document.GetElementById("hostName");
  // foreach (HtmlElement ele in es)
  // {
  if (es != null)// && es.Count != 0)
  {
  mystring = es.InnerText;
  textBox1.Text = mystring;
  // IsIPAddress(mystring.Trim());
  }
  else
  {
  errorProvider1.SetError(textBox1, "No Data");
  }
  // }
  }
  
  private void Form1_Load(object sender, EventArgs e)
  {
  webBrowser1.Navigate("http://192.168.1.1");
  }
  }
  }

  ok This is what I have now.
  
  HtmlElement PhraseInput = webBrowser1.Document.GetElementById("phrase");
  HtmlElementCollection theElements = this.webBrowser1.Document.GetElementsByTagName("input");
  if (PhraseInput != null)
  {
  PhraseInput.InnerText = "test phrase";
  
  }
  foreach (HtmlElement curElement in theElements)
  {
  if (curElement.GetAttribute("Value").Equals("submit"))
  {
  curElement.InvokeMember("click");
  }
  
  }
  
  still inputs the phrase ok but it doesn't press the button and as far as retrieving the info on the next page..you lost me :P

  how would I go about selected drop down menu items
  
  

• Lechal

  First let me say I really appreciate all your help im beginning to understand how this works but I have a few more questions.
  
  I can now edit the input boxes my question is:
  
  once I have added my text to the input box how do I press a submit button and retrieve info from the next page that loads. To give you an idea
  
  http://www.powerdog.com/wepkey.cgi
  
  That website what I am doing is using this program to input a phrase into the input box and I would like it to press submit and then retrieve the first key from the list on the following page.

  yes! you can write/edit (same thing) once you got the element you are after

  you wont be able to write to the file. its highly protected and encrypted. You could use a webbrowser control, if the router is web configurable, then kind of automate the process on the documentcompleted event of the webbrowser control and set the inputs/dropdown boxes via the aid of GetElementById using the Document property of the control. Would this get you started

  otherway is to manually do it in that, you can automatically launch an IE instance, navigate to the page you want, then control your mouse and keyboard and send keys to IE however this wouldnt be better, the first option would as everything you pretty much need is there and doesnt require you to not use your PC at the same time

  no worries. hehe, funny, I was just replying to someone with the same thing about invoking the button. I'm not sure how this will work with perl script, being the same or not but...lets give a try.

  HtmlElementCollection theElements = this.webBrowser1.Document.GetElementsByTagName("input"); 'get an input element
  foreach (HtmlElement curElement in theElements)
  {
  if (curElement.GetAttribute("Value").Equals("submit")) 'get the value of the current element. is it a submit type if so...
  {
  curElement.InvokeMember("click"); 'invoke the click event!
  }
  }

  in regards to retrieving the next page, well, in the documentcompleted event, as you have, this will be fired when the document has finished loading. So to be safe, I would suggest:

• checking the expected URL you are wanting to do your editing/parsing/operations on the page so you don't "break" the code in that, you are expecting one page but navigated to the next page where those elements you are trying to find, do not exist.

  Once checking the current page url, then execute the operations you want to execute on that method

  now, in regards to retrieving the data on the page, you need to either go through the elements as you currently are doing, or look for the innertext/outertext for the elements and see what the responses are/values are.

  innertext contains the text in that control, as well as the ability to set it
