Trying to add some code into existing project

Hi,

I'm fighting to understand how to add code found on the internet correctly into a new project.

Let me give u an example here. If i Add some code i found on the internet it gives a lot of errors. The fist error is : The type or namespace name 'Process' could not be found (are you missing a using directive or an assembly reference?)

Am I inserting the code in the wrong place. Please advice.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
// THIS IS CODE FOUND ON THE INTERNET THAT I WANT TO TEST //
// START//
// there are always multiple chrome 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"
Process[] procsChrome = Process.GetProcessesByName("chrome");
foreach (Process chrome in procsChrome)
{
// the chrome process must have a window
if (chrome.MainWindowHandle == IntPtr.Zero)
{
continue;
}
// find the automation element
AutomationElement elm = AutomationElement.FromHandle(chrome.MainWindowHandle);
// manually walk through the tree, searching using TreeScope.Descendants is too slow (even if it's more reliable)
AutomationElement elmUrlBar = null;
try
{
// walking path found using inspect.exe (Windows SDK) for Chrome 31.0.1650.63 m (currently the latest stable)
var elm1 = elm.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Google Chrome"));
if (elm1 == null) { continue; } // not the right chrome.exe
// here, you can optionally check if Incognito is enabled:
//bool bIncognito = TreeWalker.RawViewWalker.GetFirstChild(TreeWalker.RawViewWalker.GetFirstChild(elm1)) != null;
var elm2 = TreeWalker.RawViewWalker.GetLastChild(elm1); // I don't know a Condition for this for finding :(
var elm3 = elm2.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, ""));
var elm4 = elm3.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ToolBar));
elmUrlBar = elm4.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Custom));
}
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
continue;
}
// make sure it's valid
if (elmUrlBar == null)
{
// it's not..
continue;
}
// elmUrlBar is now the URL bar element. we have to make sure that it's out of keyboard focus if we want to get a valid URL
if ((bool)elmUrlBar.GetCurrentPropertyValue(AutomationElement.HasKeyboardFocusProperty))
{
continue;
}
// 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 != "")
{
// must match a domain name (and possibly "https://" in front)
if (Regex.IsMatch(ret, @"^(https:\/\/)?[a-zA-Z0-9\-\.]+(\.[a-zA-Z]{2,4}).*$"))
{
// prepend http:// to the url, because Chrome hides it if it's not SSL
if (!ret.StartsWith("http"))
{
ret = "http://" + ret;
}
Console.WriteLine("Open Chrome URL found: '" + ret + "'");
}
}
continue;
}
}
// THIS IS CODE FOUND ON THE INTERNET THAT I WANT TO TEST //
// END//
}
}
}

Thank you in advanced for all your replies!

Hi Johnny,

As per your description you are missing reference to Process namespace .Just add
using System.Text.RegularExpressions;
using System.Diagnostics;
using System.Windows.Automation;
Also you need to add a reference to
UIAutomationClient.dll and UIAutomationTypes.dll

Thank you Rajeev,

Now it ask me to add "System.Windows.Automation.AutomationElement;", but it will not accept it when im trying to add it like this:
using System.Windows.Automation.AutomationElement;

Do you know how to fix that?

The error messag is:
Error 1 The type or namespace name 'AutomationElement' does not exist in the namespace 'System.Windows.Automation' (are you missing an assembly reference?)

UPDATE: Problem solved. For some reason the UIAutomationClient.dll was not refereced to the project and now the 'using' line looks like yours above 'using System.Windows.Automation;' and not like mine 'using System.Windows.Automation.AutomationElement;'
