    Re: Manipulate/Change/Form Fill data in webpages using the Webbrowser control

    @afdoal you need to use a decaptcha service or delve into image processing (OCR)

    Can anyone help on how to simulate typing, which is a combination of onkeydown, onkeypress and onkeyup events?

    regards
    Programming is all about good logic. Spend more time here


    (vHost for Apache) (Generate pronounceable password) (Generate random number c#) (Filter array with another array)

    Re: Manipulate/Change/Form Fill data in webpages using the Webbrowser control

    @kleinma:
    I have some trouble determining the completed event.

    Code:
    ' Load the url
        Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            Dim orgurl As String = "url"
            wb.Navigate(orgurl)
        End Sub
    
    'Document completed event
        Private Sub webBrowser_DocumentCompleted(sender As Object, e As AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEvent) Handles wb.DocumentComplete
    'Change the value in the txt box, and submit  
       
    DirectCast(GetCurrentWebDoc.getElementById("ctl00_mainContent_Live3Price1_NEW_wdcDate_dateInput_TextBox"), mshtml.HTMLInputElement).value = "22/06/2012"
            DirectCast(GetCurrentWebDoc.getElementById("ctl00_mainContent_Live3Price1_NEW_Button1"), mshtml.HTMLInputElement).click()
    'AFTER submit, content will be loaded. The submit button call AJAX to load data into table. Url unchanged.
    'But the ready state already be "Complete"
    'I'v tried WebBrowserReadyState.Complete and SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE , but get the same result, their state will be "Complete", even when browser still loading the content.
            If wb.ReadyState = WebBrowserReadyState.Complete Then
                MessageBox.Show("Done")
            End If
        End Sub
    How to check if browser has completely loaded (after AJAX)?

    I have to parse the source code (after AJAX), and need to check the state of browser

    Re: Manipulate/Change/Form Fill data in webpages using the Webbrowser control

    Was wondering if you updated this to 2005 browser. I use default webbrowser (extended) that I found on some scratch code. Its actually 2005 IE. It doesn't want to convert my html source to mshtml .
    Code:
         Try
             
                Dim GetCurrentWebDoc As mshtml.HTMLDocument = DirectCast(wb.Document, mshtml.HTMLDocument)
                Dim MyDiv As mshtml.HTMLDivElement = DirectCast(GetCurrentWebDoc.getElementsByTagName("img"), mshtml.HTMLDivElement)
                If MyDiv.getAttribute("className") = "vam hand" Then
                    MessageBox.Show(MyDiv.getAttribute("onclick"))
    
                End If
    
            Catch
                MsgBox(ErrorToString, MsgBoxStyle.Critical)
            End Try

    VS 2010 converts automaticly.

    It is really not all that difficult, once you get around the casting of types to the correct kind when using the COM reference.

    This example project highlights the following manipulations (as well as opening the door to manipulate just about anything on a webpage that is possible)

    * Getting a value of an HTML input element
    * Setting a value of a HTML input element
    * Getting a value of an HTML text area
    * Setting a value of a HTML text area
    * Set HTML radio buttons selected or not
    * Click an HTML button
    * Submit an HTML Form
    * Get the sources for all images in HTML document
    * Get and display all the links in the HTML document
    * Alter non form elements (like changing the color of a DIV tag)
    * Getting values from an HTML Select element (value and selected index)
    * Display page HTML source
    * Run a javascript that is in the HTML Page
    * click a checkbox in an HTML form
    * Print the current page (with printer selection dialog)
    * Added 8/24/2006 - Highlight webpage text via code

    This specific example code is done using

    Visual Studio 2005 (VB.NET)
    However I use the COM WB Control, not the built in .NET 2.0 WB Control (because its functionality is rather limited)
    I also use a reference to the MSHTML scripting engine, which is what allows you to parse a webpage into all its elements so you can manipulate them.


    Please let me know if you have any questions/comments/suggestions.

    I can add more functionality examples if someone can think of one....

    The project page "TestPage.htm" shows signs of a budding star in web design. Some real layout talent there.

    On a more serious note, I'm sure I speak for many when I say thank you. Your post is well written and it has obviously helped many of us who still have a lot to learn. I've used your code as a starting point on more than one project. Again, thank you kleinma.

    <div aria-labelledby="255" role="textbox" g_editable="true" class="df b-K b-K-Xb URaP8 editable" id=":78.f" contenteditable="true"></div>

    How can I have success ?
