DirectoryEntry giving com exception when trying to connect ldap server using secure port

Exception snapshot
enter image description here
STEP A=>Validating the proper certificate configuration
I have a window service via which i am trying to connect the LDAP server from secure port 636 (SSL), all the certificate are properly
configured and i have verified this using the tool ldap.exe and also check the portqry tool to check if the port 636 is listening or not
and was successful in doing that.
STEP B=>Code Snippet Which is not working for secure port 636(For SSL) but working correctly with non secure port (389) A strange
observation the Below code works well when i run it as console based
application even with port 636 but fails when run as window service.

{
result_user = _searcher.FindOne();

LdapConnection ldapConnection = new LdapConnection(ldapDirectoryIdentifier);
if (useSSL)

ldapConnection.AuthType = AuthType.Negotiate;
ldapConnection.SessionOptions.VerifyServerCertificate += delegate { return true; };
}
//var networkCredential = new NetworkCredential("Hey", "There", "Guy");
var networkCredential = new NetworkCredential(user, psw, domain);
try
{
ldapConnection.Bind(networkCredential);
bool exists = UserExists("demouser1");
return true;
}
catch (Exception ex)
{
return false;
}
}
public bool UserExists(string username)
{
// create your domain context
using (PrincipalContext domain = new PrincipalContext(ContextType.Domain, "abc.domain.com", "DomainAdmin", "DomainAdmin123"))
{
// find the user
UserPrincipal foundUser = UserPrincipal.FindByIdentity(domain, IdentityType.Name, username);
return foundUser != null;
}
}
}
}
}
QUESTION Here is
Is there a problem when working with Secure port with DirectoryEntry, as LdapConnection & networkCredential works smoothly with both the ports(636 &389),
i have a legacy code which uses DirectoryEntry and i want it work for secure port as well can some one please help me, how to make the STEP B working for secure port
also.
Thanks in Advance for all the Support & guidance.

It's likely that the SSL certificate isn't trusted by the computer you're running this on.
I use Chrome to test this. Run Chrome like this (adjust for the path your Chrome is in):
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --explicitly-allowed-ports=636
Then in Chrome, go to https://abc.domain.com:636. If the certificate is trusted, you'll see a "cannot connect" kind of message. But if it is not trusted, Chrome will give you a big red warning and you know that's the problem.
To trust the cert, you need to get the root certificate (as a file, likely *.cer or *.crt) and install it on every machine that will be running your code. Here are instructions for installing a root cert in Windows: https://www.thewindowsclub.com/manage-trusted-root-certificates-windows

TestStack.White and CCleaner

I've very new to the TestStack (White) UI Automation library and I'm having a bit of an issue in terms of "hooking" the process. I'm trying to hook CCleaner, but I keep getting
An unhandled exception of type 'TestStack.White.AutomationException'
occurred in TestStack.White.dll
Additional information: Couldn't find window with title Piriform
CCleaner in process 1156, after waiting for 30 seconds:
My current code is:
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Security.Cryptography.X509Certificates;
using System.Text;
using System.Threading.Tasks;
using TestStack.White;
using TestStack.White.Factory;
using TestStack.White.UIItems.Finders;
using TestStack.White.InputDevices;
using TestStack.White.UIItems.WindowItems;
namespace NightWipe
{
class Program
{
private const string ExeSourceFile = #"C:\Program Files\CCleaner\CCleaner.exe";
private static TestStack.White.Application _application;
private static TestStack.White.UIItems.WindowItems.Window _mainWindow;
static void Main(string[] args)
{
clean();
}
public static string clean()
{
var psi = new ProcessStartInfo(ExeSourceFile);
_application = TestStack.White.Application.AttachOrLaunch(psi);
_mainWindow = _application.GetWindow("Piriform CCleaner");
_mainWindow.WaitWhileBusy();
return "";
}
}
}
I thought that maybe it was the name of the process since CCleaner starts another process (not CCleaner.exe) but CCleaner64.exe as seen here, which I can assume is for 64 bit operating systems maybe? Anyway I tried names including: "CCleaner", "CCleaner64"; but this threw the same exact exception.
I'm using Inspect by Microsoft and this is what it pulls for me (large image):
Inspect's information. Any idea what I'm doing wrong here?

The problem is that CCleaner is visible as WIN32 app. So GetWindow() doesn't work. You can try this code:
public void CCleanerSample()
{
var application = Application.AttachOrLaunch(new ProcessStartInfo(#"C:\Program Files\CCleaner\CCleaner.exe"));
AutomationElement ccleanerAutomationElement = null;
Console.Write("Waiting till WIN32 app is launching");
while (ccleanerAutomationElement == null)
{
ccleanerAutomationElement = AutomationElement.RootElement.FindFirst(TreeScope.Children,
new PropertyCondition(AutomationElement.NameProperty, "Piriform CCleaner"));
Thread.Sleep(1000);
Console.Write(".");
}
Console.WriteLine(" Done");
var mainWindow = new Win32Window(ccleanerAutomationElement, WindowFactory.Desktop, InitializeOption.NoCache,
new WindowSession(application.ApplicationSession, InitializeOption.NoCache));
}

Why can't I connect to an online MS Team Foundation project with C#

I have looked at various examples, and there are few/none connecting to an online TFS account, connecting to a TFS project. Below is the last attempted code, that also didn't work. Yes, I am a neophyte to VS .Net (C#). Any direction is greatly appreciated:
using System;
using System.Collections.ObjectModel;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.Framework.Common;
using Microsoft.TeamFoundation.Framework.Client;
namespace TfsApplication
{
class Program
{
static void Main(String[] args)
{
Uri collectionUri = new Uri("https://drmpractice.visualstudio.com");
TfsTeamProjectCollection collection =
new TfsTeamProjectCollection(
collectionUri,
new System.Net.NetworkCredential(#"myEmail#hotmail.com", "MyPassword"));
WorkItemStore workItemStore = collection.GetService<WorkItemStore>();
}
}
}
The returned error returned: "password, port, or project name is wrong".

C# MailMessage Display email instead of Send

I have been following the example below to send email using C# code with success:
MSDN Mail Message
However, I would like the code to display the composed email message on user machine, so that user can have a final check before hitting send button on outlook.
In the VBA world, I can use mail.Display in place of mail.Send.
Can anyone provide some advice to achieve that in C#?
Thanks.

How about this...
private void btnEmail_Click(object sender, EventArgs e)
{
string command = "mailto:somebody#domain.com?subject=The Subject&bcc=another#codegaim.com&body=Hi,I found this website and thought you might like it http://www.geocities.com/wowhtml/";
Process.Start(command);
}

Found a great solution to my problem i.e. to use Microsoft Office Interop Outlook instead of System.Net.MailMessage
followed this:

// Next 2 lines are optional. if not specified, the default account will be used
Outlook.Account account = Application.Session.Accounts["MyOtherAccount"];
mail.SendUsingAccount = account;
mail.Display(false); // To Display
//mail.Send(); // To Send
}
}
}

how to fix Webexception unhandle

wc.Credentials = CredentialCache.DefaultCredentials;
wc.Headers.Add(HttpRequestHeader.UserAgent, "anything");
wc.DownloadFile(uri, filename);
}
}
}
}
can any one help me.

I'm guessing your WebException occurs on the last line (please in future include that in your question - we can't really help you based on guesswork).
wc.DownloadFile(uri, filename);
From the documentation on this method call, it will throw a WebException if one of the following is true:
The URI formed by combining BaseAddress and address is invalid.
filename is null or Empty.
The file does not exist.
An error occurred while downloading data.
We can rule out #2 immediately, as you've set that. To find out which of these situations you've got, try looking at the exception's message property (or the message property of the inner exception if there is one).
