Get URL from Opera browser

I am trying to get URL from Opera browser, I assumed it is the same as for Chrome but I was wrong since it doesn't work this way.

whatever I have done so far is:

    public static string GetURL(IntPtr intPtr, string programName, out string url)
    {
        string temp = null;
            if (programName.Equals("opera"))
        {
        //    // there are always multiple opera processes, so we have to loop through all of them to find the
        //    // process with a Window Handle and an automation element of name "Address and search bar"
          /*  string x = "";
            DdeClient dde = new DdeClient("opera", "WWW_GetWindowInfo");
            try
            {
                //temp := RequestData('0xFFFFFFFF');
                dde.Connect();
                string url1 = dde.Request("URL", int.MaxValue);
                string[] text = url1.Split(new string[] { "\",\"" }, StringSplitOptions.RemoveEmptyEntries);
                dde.Disconnect();
            }
            catch (Exception)
            {
                x = "failed";
             }
*/



            Process[] procsOpera = Process.GetProcessesByName("opera");
            foreach (Process opera in procsOpera)
            {
                // the chrome process must have a window
                if (opera.MainWindowHandle == IntPtr.Zero)
               {
                      continue;
                }

                // find the automation element
                AutomationElement elm = AutomationElement.FromHandle(opera.MainWindowHandle);
                AutomationElement elmUrlBar = elm.FindFirst(TreeScope.Descendants,
                  new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));

                // if it can be found, get the value from the URL bar
                if (elmUrlBar != null)
                {
                    AutomationPattern[] patterns = elmUrlBar.GetSupportedPatterns();
                    if (patterns.Length > 0)
                    {
                        ValuePattern val = (ValuePattern)elmUrlBar.GetCurrentPattern(patterns[0]);
                        temp = val.Current.Value.ToString();
                        url = val.Current.Value.ToString();
                    }
                    else
                    {
                        temp = "";
                        url = "";
                    }
                }
                else
                {
                    temp = "";
                    url = "";
                }
            }
        }
        url = temp;
        return temp;
    }

I have tried it with both NDDE client and automation element, but both are failed :( I think in automation element the problem is in this line

AutomationElement elmUrlBar = elm.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));

Perhaps for opera it isn't "Address and search bar" can some 1 help me to solve the issue please?

NOTE: There are couple question where chrome and opera tagged but there is no Opera working answer inside on SO.

Changed your function and made it simple as possible. Works with the current Opera version 47.0

public static string GetOperaURL()
    {
        string url = "";

        Process[] procsOpera = Process.GetProcessesByName("opera");
        foreach (Process opera in procsOpera)
        {
            // the chrome process must have a window
            if (opera.MainWindowHandle == IntPtr.Zero)
            {
                continue;
            }

            // find the automation element
            AutomationElement elm = AutomationElement.FromHandle(opera.MainWindowHandle);
            AutomationElement elmUrlBar = elm.FindFirst(TreeScope.Descendants,
                new PropertyCondition(AutomationElement.NameProperty, "Address field"));

            // if it can be found, get the value from the URL bar
            if (elmUrlBar == null) continue;

            AutomationPattern pattern = elmUrlBar.GetSupportedPatterns().FirstOrDefault(wr=>wr.ProgrammaticName == "ValuePatternIdentifiers.Pattern");

            if (pattern == null) continue;

            ValuePattern val = (ValuePattern)elmUrlBar.GetCurrentPattern(pattern);
            url = val.Current.Value;
            break;
        }

        return url;
    }

Get Process id for opera:

public static void GetOperaURL()
{
   Process[] OProcesses = Process.GetProcessesByName("opera");
   string url = null;
   foreach (Process proc in OProcesses)
   {
       if (proc.MainWindowHandle != IntPtr.Zero)
       {
            url = getOperaUrlFromProcess(proc);
            break;
        }
    }
}

Use automation element for determining URL
private static string getOperaUrlFromProcess(Process proc) { // find the automation element AutomationElement elm = AutomationElement.FromHandle(proc.MainWindowHandle); // manually walk through the tree, searching using TreeScope.Descendants is too slow (even if it's more reliable) AutomationElement elmUrlBar = null; try { var elm1 = elm.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Browser container")); if (elm1 == null) { return null; } elmUrlBar = elm.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Address field")); } catch { // Chrome has probably changed something, and above walking needs to be modified. :( // put an assertion here or something to make sure you don't miss it return null; } // make sure it's valid if (elmUrlBar == null) { // it's not.. return null; } // there might not be a valid pattern to use, so we have to make sure we have one AutomationPattern[] patterns = elmUrlBar.GetSupportedPatterns(); if (patterns.Length == 1) { string ret = ""; try { ret = ((ValuePattern)elmUrlBar.GetCurrentPattern(patterns[0])).Current.Value; } catch { } if (ret != "") { return ret; } return null; } return null; }

You can download the NDde dll. After adding a reference simply just copy this code to where you want to get the url.

NDde DLL Download : http://ndde.codeplex.com/

DdeClient dde = new DdeClient("opera", "WWW_GetWindowInfo");
dde.Connect();
string url = dde.Request("URL", int.MaxValue);
string[] text = url.Split(new string[] { "\",\"" }, StringSplitOptions.RemoveEmptyEntries);
dde.Disconnect();

If you want to get firefox data simply change the opera to firefox

DdeClient dde = new DdeClient("firefox", "WWW_GetWindowInfo");
dde.Connect();
string url = dde.Request("URL", int.MaxValue);
string[] text = url.Split(new string[] { "\",\"" }, StringSplitOptions.RemoveEmptyEntries);
dde.Disconnect();

In a function

private string GetBrowserURL(string browser) {
    try {
        DdeClient dde = new DdeClient(browser, "WWW_GetWindowInfo");
        dde.Connect();
        string url = dde.Request("URL", int.MaxValue);
        string[] text = url.Split(new string[] { "\",\"" }, StringSplitOptions.RemoveEmptyEntries);
        dde.Disconnect();
        return text[0].Substring(1);
    } catch {
        return null;
    }
}

You can use Inspect which offers the same functionality as UISpy to get the AutomationId from the Opera UI. I assume the reason it is not working is because it is named differently in Opera.
