Open webbrowser, auto complete form components and submit

.net, browser, c#, winforms, wpf

Solution

I wrote an example for filling in an element in a html page. You must do something like this:

Winform

public Form1()
        {
            InitializeComponent();
            //navigate to you destination 
            webBrowser1.Navigate("https://www.certiport.com/portal/SSL/Login.aspx");
        }
        bool is_sec_page = false;
        private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            if (!is_sec_page)
            {
                //get page element with id
                webBrowser1.Document.GetElementById("c_Username").InnerText = "username";
                webBrowser1.Document.GetElementById("c_Password").InnerText = "pass";
                //login in to account(fire a login button promagatelly)
                webBrowser1.Document.GetElementById("c_LoginBtn_c_CommandBtn").InvokeMember("click");
                is_sec_page = true;
            }
            //secound page(if correctly aotanticate
            else
            {
                //intract with sec page elements with theire ids and so on
            }

        }

Wpf

public MainWindow()
        {
            InitializeComponent();
     webBrowser1.Navigate(new Uri("https://www.certiport.com/portal/SSL/Login.aspx"));
            }
            bool is_sec_page = false;
            mshtml.HTMLDocument htmldoc;
            private void webBrowser1_LoadCompleted(object sender, NavigationEventArgs e)
            {
                htmldoc = webBrowser1.Document as mshtml.HTMLDocument;
                if (!is_sec_page)
                {
                    //get page element with id
                    htmldoc.getElementById("c_Username").innerText = "username";
                    //or
                    //htmldoc.getElementById("c_Username")..SetAttribute("value", "username");
                    htmldoc.getElementById("c_Password").innerText = "pass";
                    //login in to account(fire a login button promagatelly)
                    htmldoc.getElementById("c_LoginBtn_c_CommandBtn").InvokeMember("click");
                    is_sec_page = true;
                }
                //secound page(if correctly aotanticate
                else
                {
                    //intract with sec page elements with theire ids and so on
                }
            }

Just navigate to specific URL and fill page element.

Problem

We are currently investigating a method of creating a WPF/winforms application that we can set up internally to :- - automatically open a new instance of a web browser to a predefined URL - automatically complete required fields with predefined data - automatically submit form and wait for the next page to load - automatically complete required fields with predefined data (page 2) - automatically submit form and wait for the next page to load (etc) after much investigation, the only thing we have managed to find is the opening up of a web browser via :- ``` object o = null; SHDocVw.InternetExplorer ie = new SHDocVw.InternetExplorer(); IWebBrowserApp wb = (IWebBrowserApp)ie; wb.Visible = true; wb.Navigate(url, ref o, ref o, ref o, ref o); ``` Any advice / reading recommendations would be appreciated on how to complete the process.
