WatiN LogonDialogHandlers not working correctly in Windows 7

Question

I have recently updated to Windows 7, VS2010 and IE8. We have an automation suite running tests against IE using WatiN. These tests require the logon dialog handler to be used in order to log different AD Users into the IE Browser.

This works perfectly when using Windows XP and IE8, but now using Windows 7 has resulted in the Windows Security dialog box no longer being recognised, the dialogue box is just being ignored. This is the method being used to startup the browser:

        public static Browser StartBrowser(string url, string username, string password)
        {
            Browser browser = new IE();
            WatiN.Core.DialogHandlers.LogonDialogHandler ldh = new WatiN.Core.DialogHandlers.LogonDialogHandler(username, password);
            browser.DialogWatcher.Add(ldh);
            browser.GoTo(url);
            return browser;
        }

any suggestions or help would be greatly appreciated...

Answer 1

For whatever reason the code Clint posted had comments instead of entering the username, password and submitting, and referenced an undefined method, but is otherwise OK. Here's some completed (and working) code:

    public static Browser Win7Login(string username, string password, string URL) {
        Process ieProcess = Process.Start("iexplore.exe", URL);
        ieProcess.WaitForInputIdle();

        Thread.Sleep(2000);

        AutomationElement ieWindow = AutomationElement.FromHandle(ieProcess.MainWindowHandle);
        string t = ieWindow.Current.ClassName.ToString();

        Condition conditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                   new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Window));
        Condition List_condition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                        new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ListItem));
        Condition Edit_condition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                    new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
        Condition button_conditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                     new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button));

        AutomationElementCollection c = ieWindow.FindAll(TreeScope.Children, conditions);
        foreach (AutomationElement child in c) {
            if (child.Current.ClassName.ToString() == "#32770") {
                // find the list
                AutomationElementCollection lists = child.FindAll(TreeScope.Children, List_condition);
                // find the buttons
                AutomationElementCollection buttons = child.FindAll(TreeScope.Children, button_conditions);

                foreach (AutomationElement list in lists) {
                    if (list.Current.ClassName.ToString() == "UserTile") {
                        AutomationElementCollection edits = list.FindAll(TreeScope.Children, Edit_condition);
                        foreach (AutomationElement edit in edits) {
                            if (edit.Current.Name.Contains("User name")) {
                                edit.SetFocus();
                                ValuePattern usernamePattern = edit.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
                                usernamePattern.SetValue(username);
                            }
                            if (edit.Current.Name.Contains("Password")) {
                                edit.SetFocus();
                                ValuePattern passwordPattern = edit.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
                                passwordPattern.SetValue(password);
                            }
                        }
                    }
                }
                foreach (AutomationElement button in buttons) {
                    if (button.Current.AutomationId == "SubmitButton") {
                        InvokePattern submitPattern = button.GetCurrentPattern(InvokePattern.Pattern) as InvokePattern;
                        submitPattern.Invoke();
                        break;
                    }
                }
            }
        }
        return IE.AttachTo<IE>(Find.By("hwnd", ieWindow.Current.NativeWindowHandle.ToString()), 30);
    }

This can also be refactored as a DialogHandler like this:

public class Windows7LogonDialogHandler : BaseDialogHandler
{
    private readonly string _username;
    private readonly string _password;
    AndCondition _conditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                   new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Window));

    readonly AndCondition _listCondition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                    new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ListItem));

    readonly AndCondition _editCondition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));

    readonly AndCondition _buttonConditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                 new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button));

    public Windows7LogonDialogHandler(string username, string password)
    {
        _username = username;
        _password = password;
    }

    public override bool HandleDialog(Window window)
    {
        if(CanHandleDialog(window))
        {
            var win = AutomationElement.FromHandle(window.Hwnd);
            var lists = win.FindAll(TreeScope.Children, _listCondition);
            var buttons = win.FindAll(TreeScope.Children, _buttonConditions);
            var another = (from AutomationElement list in lists
                           where list.Current.ClassName == "UserTile"
                           where list.Current.Name == "Use another account"
                           select list).First();
            another.SetFocus();

            foreach (var edit in from AutomationElement list in lists
                                 where list.Current.ClassName == "UserTile"
                                 select list.FindAll(TreeScope.Children, _editCondition)
                                     into edits
                                     from AutomationElement edit in edits
                                     select edit)
            {
                if (edit.Current.Name.Contains("User name"))
                {
                    edit.SetFocus();
                    var usernamePattern = edit.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
                    if (usernamePattern != null) usernamePattern.SetValue(_username);
                }
                if (edit.Current.Name.Contains("Password"))
                {
                    edit.SetFocus();
                    var passwordPattern = edit.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
                    if (passwordPattern != null) passwordPattern.SetValue(_password);
                }
            }
            foreach (var submitPattern in from AutomationElement button in buttons
                                          where button.Current.AutomationId == "SubmitButton"
                                          select button.GetCurrentPattern(InvokePattern.Pattern) as InvokePattern)
            {
                submitPattern.Invoke();
                break;
            }
            return true;
        }
        return false;
    }

    public override bool CanHandleDialog(Window window)
    {
        return window.ClassName == "#32770";
    }
}

Which is a little bit nicer. You can then use it like this:

using(var ie = new IE())
        {
            ie.DialogWatcher.Add(new Windows7LogonDialogHandler(@"domain\user", "password"));
            ie.GoTo("http://mysecuredwebsite");
        }

Answer 3

We have eventually solved this issue by using the Windows Automation 3.0 API to pick up the dialogue box and handle the logging in. This was done as follows:

1. Fire up an IE process and assign it to an AutomationElement
2. You now have the ability to traverse through the child elements of the IEFrame, picking up the username and password Edit fields.
3. Then send the username and password

Once the browser has been authenticated we then attach it to a WatiN IE browser object. The code follows below:

        public static Browser LoginToBrowser(string UserName, string Password, string URL)
    {

        AutomationElement element = StartApplication("IEXPLORE.EXE", URL);
        Thread.Sleep(2000);
        string t = element.Current.ClassName.ToString();

             Condition conditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                        new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Window));
            Condition List_condition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                            new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ListItem));
            Condition Edit_condition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                        new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
            Condition button_conditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                         new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button));

        AutomationElementCollection c = element.FindAll(TreeScope.Children, conditions);
        foreach (AutomationElement child in c)
        {
            if (child.Current.ClassName.ToString() == "#32770")
            {
                //find the list
                AutomationElementCollection lists = child.FindAll(TreeScope.Children, List_condition);
                // find the buttons
                AutomationElementCollection buttons = child.FindAll(TreeScope.Children, button_conditions);

                foreach (AutomationElement list in lists)
                {
                    if (list.Current.ClassName.ToString() == "UserTile")
                    {
                        AutomationElementCollection edits = list.FindAll(TreeScope.Children, Edit_condition);
                        foreach (AutomationElement edit in edits)
                        {
                            if (edit.Current.Name.Contains("User name"))
                            {
                                edit.SetFocus();
                                //send the user name
                            }
                            if (edit.Current.Name.Contains("Password"))
                            {
                                edit.SetFocus();
                                //send the password
                            }
                        }
                    }
                }
                foreach (AutomationElement button in buttons)
                {
                    if (button.Current.AutomationId == "SubmitButton")
                    {
                        //click the button 
                        break;
                    }
                }
            }            
        }
        return IE.AttachToIE(Find.By("hwnd", element.Current.NativeWindowHandle.ToString()), 30) ;
    }

We did use a tool called UI Spy to examine the Windows UI. If you run it against XP and Win7 you can clearly see how the structure of the Windows Security dialogue box has changed between the 2 OS's.

Nicholas Riley post works like a charm, however including the using System.Windows.Automation might be a little tricky. I thought microsoft would put this in the GAC, but they do not, at least for me running Windows 7 professional. I even downloaded the Automation Toolkit from here.

Turns out, there is a subject here on stack overflow that shows where the dll's are that you can browse to include as references in your project. The link for that is here.

Essentially, you just need to reference two dll's. UIAutomationClient.dll and UIAutomationTypes.dll (both in the same directory).
