This is very applicable. I will take a look. Thanks for sharing!

What do you need, and what do the connections have in common?
You will find that OldDbConnection and SqlConnection (among others) inherit from Common.DbConnection (which also has an interface).
You can pass a class instance that another class "inherits" from (or an interface) if it meets your requirements instead of having to resort to generics (in this case).

I'm very new to Active Directory, so bear with me please...
First
I'm using the following to validate a user:
public bool ValidateUser(Credentials credentials, string userName = "", string password = "")
{
using (var context = new PrincipalContext(ContextType.Domain, credentials.ServerName, credentials.UserName, credentials.Password))
{
return context.ValidateCredentials(userName, password);
}
}
But the ValidateCredentials takes the password in PLAIN TEXT and it works fine. This doesn't seem right. How is encryption handled? How do you encrypt the text and how does AD know the PW is encrypted?
Second
Next, I know that LDAP is a protocol. From what I see you specify LDAP in the
query string, as in "LDAP://OU=staffusers,DC=leeds-art,DC=ac,DC=uk"
Is this the way it's done? How do you specify another protocol to use?
Thanks

1) You don't encrypt the text. You're correct is questioning "how does AD know the PW is encrypted?". It doesn't. The function you're calling is running on your machine, not the server. The method hashes the password for you, gets the encrypted account details, including password, from the domain controller and makes the comparison locally. The password never leaves the machine.
2) Go through this: Howto: (Almost) Everything In Active Directory via C#[^]

I figured that's what happening. Do you know of any docs that state this?

Did you even consider a scenario where it is not encrypted?

By prefixing it with the protocol-handler[^]. For ftp we use the ftp:// prefix, for webpages http, etc. You can even register custom prefixes.

Good morning to all!
I need to show two headers in a listview control, I've been looking for information about it, but I don't found it.
Can help me?

|

Yes, use the WPF ListView's GridView.

Create your own customized Listview which basicly is a UserControl.
Inside this UserControl you have your Headers a needed (Labels) and the ListView under the Header-Labels.

Hello, I have inherited some C#.NET code that builds a dynamic dashboard on page load. The dynamic dashboard consists of a table and 2 rows - one row showing online devices, the other row showing offline devices. My issue is that if there are more than 5 devices on a given row, the row gets cluttered and looks terrible. I would like to break the line at 4 devices, but I am so confused by the logic. I have spent the last 48 hours swirling through this code and trying to find where to break the line and how - I am still lost. Please, any help would be very much appreciated. Please see a snapshot of the code below. Thank you so much in advance. -Jason

All,
I am new to C# code, I am trying to achieve copying the file from SFTP location to SQL Azure using SQL Bulk copy method. This I can achieve,but when I am trying to use foreach loop to read multiple files from SFTP file list I couldn’t able do it.
I can’t copy paste my code here, could some one out here help me out how can I achieve this specific to Azure DB ?
TIA.

Sooooo, you want help fixing your code which we can't see and can't possibly guess at what it looks like?
Good luck with that.

Thank you , I tried with one file it is working fine.When I try to loop Multiple files coming from SFTP source I am having this issue.

Try 2 in a row.
Wrap it in a try ... catch block and display the exception, if any.

You're going to have to go into detail about what you mean by "configured/enabled".
Are you asking how to find out if AD is running on a remote server?

Well, you can't interrogate a single server without permissions to do so, and you're usually not going to have those.
Like Pete showed, if the machine your code is running on is part of the domain, you can just ask the domain for it's list of available domain controllers within reach of your machine.
But, it's even simpler than that. The fact that your machine is joined to a domain means there's at least one domain controller, and hence, Active Directory exists, or at least existed when the machine was joined to the domain.
If GetCurrentDomain doesn't return anything, well, there's no domain and hence, no Active Directory.

I suppose one way would be to interrogate the domain controllers. Something like this might work:
public bool IsDomainEnabled()
{
return Domain.GetCurrentDomain()?.DomainControllers.Any() ?? false;
}Note, I just typed this off the top of my head so there may be a syntax error or two in there.
