Way To Instantiate NTAccount Class From An Active Directory Entry?
Aug 23, 2007
I am creating user accounts in Active Directory via vb.net.Once the account is created I need to assign permissions to the "homedirectory" that I have assigned in Active Directory.I have access to the Active Directory name attributes but I need to convert these to a NT account format ( DOMAINAccountName ) to add security via the DirectorySecurity AddAccessRule method.Is there a way to instantiate the NTAccount class from an Active Directory Entry? I'm not sure if this is necessary I just found that class and it looked like a good fit; a simple routine to create the DOMAINAccountName from the Directory Entry attributes like cn might also suffice.

i found this code to update a property on an active directory entry:
If user.Properties.Contains("title") Then
user.Properties("title")(0) = employeeTitle.SelectedItem.Text
Else
user.Properties("title").Add(employeeTitle.SelectedItem.Text)
End If
I understand it except for the ("title)(0). why is this a double index array. what does the (0) do?

I have an Account Class that is able to create notes(Class), however i am able to create the note object by itself which is not the desired outcome, i want only the account class to be able to create the note object. Another Example would be, an order item should not be created without an order class. But how do you enforce this in vb.net.

Is it possible (I'm sure it is) to validate a user's credentials against Active Directory without using Directory Services?I'm building a Browser-Based WPF application which requires users to login to and get validated via Active Directory. Since .Net 4.0 (or maybe 3.5) accessing Directory Services from an Application requires the application to be fully trusted. Since IE won't provide full trust to an application if it doesn't have the signing certificate in it's cert store, the application is refused startup permission.
If I don't use Directory Services, then I can leave the application as Partial Trust and validate my user's credentials without having to install a certificate on each user's machine.

I'm trying to decide whether to get a value, call it X, in my class through a read only property or through a function. Normally I'd code it as a property except in this case the GET involves doing a lookup to a sql table. So there's way more overhead than a simple RETURN X. So my question is, when I instantiate a new object from my class, are all the properties calculated at that point, so that the sql lookup will occur too? Or is the property only evaluated when I actually reference it in the calling code.

this is what i want to do. I have a class library project into my solution. Into it i have a class. I want that class to be instantiated as soon as the solution starts. So it can be accesible from the other projects in the solution like this: Namespace.InstanceOfTheForm.Property Is there any way to do that? or something close to that?

I am currently playing around with VB.Net using Visual Studio 2010 (.Net 4.0) and I need your help to create a collection class (let's call it 'cl_MyCollection') with a constructor that accepts two arguments:An SqlDataReader object Some means of pointing to a custom class I have created.I have five database tables in SQL 2000 and five VB.Net custom classes.Each custom class contains a variable for each field of the table the class represents.For example:"tbl_User" has 2 fields "User_ID" and "User_Name" and tbl_Family" has 3 fields "Family_ID", "Family_Name" and "Family_ Location". [code] Fixed typo, the select case now points to the second argument ('selectedClass') as originally intended.

I'm sure I've seen this done in 4.0 but can't remember how it is done.
Basically I want to instantiate a class and call a method of that class on the same line of code.
So something like this

I am trying to run a backgroundworker to load data from my DAL (which is available in another class). I want to keep the UI available and not have the "locked up" feel while the object is loading.When I create a simple backgroundworker and Sleep the UI stays responsive and my controls can be updated after the sleep. As soon as I replace the sleep with a call to instantiate the object from my DAL, the UI locks up. Is there someway I can instantiate this object using the background worked and keep the UI responsive?
When the situation object is instantiated it could take several seconds for it to load completely, during this time is when the UI is locked up... It does eventually load just fine.
Private WithEvents backWork As New BackgroundWorker()
Dim sit As Situation
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles btnLoad.Click

I'm having a weird problem with active directory and the display name attribute. I can create an AD account with no problems, the account shows up, I can log on as the account, everything appears to be working as intended. The problem is, our company requires that the display name be in the form of "Lastname, Firstname". Thats all fine and dandy when you create an AD account use the MMC snap-in, you type in the users name as "Lastname, Firstname" in the display name field and when the account is created, the display name shows as "Lastname, Firstname" as you would expect.
The problem I am having is this, whenever I create an AD account programmatically, I can't for the life of me get the display name to show up as "Lastname, Firstname". The displayname property is set as such, checking the AD account using the MMC snap-in shows the display name is set correctly, but when looking at the list of user accounts, the account is always displayed as the users username. The account name I am using is "Test User", see pic below.
if you try to rename the account, the field it tells you it is editing is called Full Name? I can't find a property in AD even called Full Name so I am completely confused, here is a picture of me trying to rename the programmatically created account, as you can see, the display name field is set correctly even though it doesn't display that way. And of course, after renaming the account as seen below, the display name shows up correctly as "Lastname, Firstname"Here is the code I use to create the account, just for reference.
Public Sub CreateActiveDirectoryAccount(ByVal sUserName As String, ByVal sFirstName As String, _
ByVal sLastName As String, ByVal sUserPrincipalName As String, ByVal sPassword As String, _
ByVal sHomeDrive As String, ByVal sHomeDirLocation As String, _

Im trying to connect to AD and carry out some basic tasks for a .Net application written in VB .Net. I would like to create the application so when it loads, it automatically binds to the default AD domain that the user is logged onto. This has led me to writing the code
Dim domain As DirectoryEntry = New DirectoryEntry("LDAP://DC=domain,DC=com", Nothing, Nothing, AuthenticationTypes.Secure)
domain.RefreshCache()
But this doesnt work.

I have a list of computers from the AD which also have IP addresses in one of the fields. The IP address does not seem to be accurate. It looks like the AD updates are not as frequent as the DHCP server.
MYCOMPUTER1 1.1.1.1
MYCOMPUTER2 2.2.2.2
MYCOMPUTER3 3.3.3.3
Is there anyway to get the IP address from VB soon after I retrieve the record from AD? Querying the DNS/DHCP server via code?
