    @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?

    Programming is all about good logic. Spend more time here

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

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

    I have some trouble determining the completed event.

    ' 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"
        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
            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 .
                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
                End If
                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....

    This looks to be exactly what i need to start on a tool at the company i work for, do you have it on VB 2010? i am having dificulties to open it.
    Any idea how to solv this?

    Thank you any way, im sure iŽll find a way to make it work.
    Best regards.

    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.

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

    Dear every predecessors,

    This is a super helpful thread. I am not sure if anyone still following the thread, I hope there is a little chance somebody could help

    Right now, I am trying to fill forms on website, I did it with "Sendkeys", but by reading #196, it is not appropriate.

            TextBox1.Text = WebBrowser1.Url.ToString
        Private Property pageready As Boolean = False
    #Region "Page Loading Functions"
        Private Sub WaitForPageLoad()
            AddHandler WebBrowser1.DocumentCompleted, New WebBrowserDocumentCompletedEventHandler(AddressOf PageWaiter)
            While Not pageready
            End While
            pageready = False
        End Sub
        Private Sub PageWaiter(ByVal sender As Object, ByVal e As WebBrowserDocumentCompletedEventArgs)
            If WebBrowser1.ReadyState = WebBrowserReadyState.Complete Then
                pageready = True
                RemoveHandler WebBrowser1.DocumentCompleted, New WebBrowserDocumentCompletedEventHandler(AddressOf PageWaiter)
            End If
        End Sub
    #End Region
    I believe that the login form is an ActiveX control ttps://
    The source code of the password field:
    <OBJECT onkeyup="getfocus1('KeyPart', event);detectCapsLock('logonform','safeEdit1',500,300,400,'logontb');" onfocus="detectCapsLock('logonform','safeEdit1',500,300,400,'logontb')" onblur="closeCapTip('logonform','safeEdit1')" id=safeEdit1 codeBase="/icbc/newperbank/,0,0,13" classid=CLSID:73E4740C-08EB-4133-896B-8D0A7C9EE3CD width=145 height=21><PARAM NAME="_cx" VALUE="3836"><PARAM NAME="_cy" VALUE="556"></OBJECT>
    Is there a way to pass value into the password field with it ID/name??

    Thank you for any advice!!!
