I'm trying to create an application where i can browse the Active Directory OU folder structure. I need to select an OU and need the OU name for a next action in the application.
Any help is welcome.

Already found some information like this below, but it doesn't show any results:
mports System
Imports System.DirectoryServices
Public Class Form1
Class DirLister
Shared Sub Main(ByVal args() As String)
Dim enTry As DirectoryEntry = New DirectoryEntry("LDAP://192.168.1.1")
Dim mySearcher As DirectorySearcher = New DirectorySearcher(enTry)
mySearcher.Filter = ("(objectClass=computer)")
Dim resEnt As SearchResult
For Each resEnt In mySearcher.FindAll()
Form1.Text = (resEnt.GetDirectoryEntry().Name.ToString())
Next
End Sub
End Class
|
|
|
|
|
Replace this line :
Dim enTry As DirectoryEntry = New DirectoryEntry("LDAP://servername/DC=DCNAME, DC=local")
hopes it helps,

That didn't work either, i also changed it after your suggestion into:
Imports System
Imports System.DirectoryServices
Public Class Form1
Class DirLister
Shared Sub Main(ByVal args() As String)
Dim enTry As DirectoryEntry = New DirectoryEntry("LDAP://mydomain.local/RootDSE")
Dim mySearcher As DirectorySearcher = New DirectorySearcher(enTry)
mySearcher.Filter = ("(objectClass=computer)")
Dim resEnt As SearchResult
For Each resEnt In mySearcher.FindAll()
Form1.Text = (resEnt.GetDirectoryEntry().Name.ToString())
Next
End Sub
End Class
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
End Class
Do i forgot something? I just want to test this with display the results at my empty form and work from there with the results.

Can you tell me what is not working correctly. Is it that you are not getting the required results or that you are getting an error message.

Ummm... To be frank, you're copying and pasting code that you don't understand at all, and I'm not talking about the directory searching code. It's this
Form1.Text = blah, blah, blah
in int your Main. The search code may actually be working, but since you put all this in the Main method, before the form even shows on the screen, you'll never see the results. And, the Text property of the Form just changes the TitleBar text. It doesn't show up in the form itself.
Get rid of Main method and move it into the Form_Load event. Add a ListBox to the Form and expand it to cover the form. Then change the code in the Form_Load event:
Dim enTry As DirectoryEntry = New DirectoryEntry("LDAP://your AD server/AD path to search")
Dim mySearcher As DirectorySearcher = New DirectorySearcher(enTry)
mySearcher.Filter = "(objectClass=Computer)"
Dim resEnt As SearchResult
For Each resEnt In mySearcher.FindAll()
ListBox1.Items.Add(resEnt.GetDirectoryEntry().Name)
Next

Thank you, i got it working with your supplied code. Just need some finetuning now, but this is working.

I also got i working with a treeview and a OU list. I changed:
ComboBox1.Items.Add(resEnt.GetDirectoryEntry().Name)
into:
TreeView1.Nodes.Add(resEnt.GetDirectoryEntry().Name)
The problem now is that i only see a list of OU's and not into a real treeview.
So i see:
OU1
OU2
OU3
OU1a
OU1b
Instead of:
- OU1
- OU1a
- OU1b
etc.
How can i get this working?

Your searching the entire subtree under the starting container. Don't.
The trick is to populate only the top level of the treeview, putting a dummy child under each leaf so you get the little plus sign next to it. Upon the user clicking each node, you have to requery AD to get the containers under that particular node, and fill in the nodes under the node that was clicked.
Didn't think this was going to be that complicated, did you?

Warning 5 Unused local variable: 'k'. Line 97 Column 13
What is going wrong?

This code is used for making a custom control. You really don't want to to use it unless you're making your own.
And yes, it IS that complicated. No, I don't have any example code for doing this.

Hi,
I dont know how to open the existing pdf file(out side of the form) in visual basic.
I used shell command, but one problem happened. While first pdf open means it is not opened, while openning second pdf file on the same run time the first file ans second file both are opened.I dont know y this problem.
Also how to search particular word in PDF using VB code?. I need both answers. I am very much struglling bcoz of this.
My advance Thanks For that Guy.

There are free and commerical PDF libraries for .NET. There is no PDF support built in, Process.Start to start a viewer is the best you can hope for, or perhaps using IE as a control to view them.

If you convert the date into a DateTime object, there is a DayOfWeek property in the DateTime that you can check to see if it is Sunday. It returns a enumeration.
Dim dt As New DateTime(2003, 5, 1)
If dt.DayOfWeek = DayOfWeek.Sunday Then
End If
Hope that helps.

Use the Anchor property to set where controls move on a resize of the form, and set the Size property, as you already are, to resize it.

Hi
when the user press Enter key on datagridview the focus goto the next row , ant Tab key go to the next cell ..
How can I prevent that to use Entyer/Tab keys in any other use ..
jooooo
|
|
|
|
|
you can use the keypress event of the datagridview.
check which key was pressed.if enter key then move the focus to the previous row and if tab key then move the focus to the previous cell.
hopes it helps,

Hi,
I am using VB .Net 2.0 thik client application(Winform) and in one case I need to creat the kind of function, which will be provided class name(string) as parameter and that function will return object of that class, like,
if (blnCustomerSelected)
{
dim objCustomer = GetObject("Customer")
textbox1.text = objCustomer.FName
textbox2.text = objCustomer.EmailID
....
}
else if product then
{
dim objProduct = GetObject("Product")
textbox1.text = objProduct.Name
textbox2.text = objProduct.Rate
textbox3.text = objProduct.ID
....
..
}
so what would be the definition of GetObject() in this case?
TIA
Best Regards,
Niraj Parikh

Sounds like you need to write a factory class. A factory class would check the string passed in, and have a switch or something to return an instance of that type. It looks like you really want to load a specific product/customer here tho, although that's not clear in your getobject call.
Of course, this means that your code is not typesafe, I assume Customer and Product do not have a common base beyond object. But, I guess VB isn't that type safe to begin with.
I presume you don't REALLY have objects called textbox1 and textbox2 in your code ?

Hi Graus,
Thanks for your reply, yes its not my real objects, its just kind of algoritham using which I just wanted to explain what I want,
pls dont consider the syntax just the concept is I need to have object at runtime and my classtime is not fixed, it come at runtime in form of string so if function accepts "class1" then it should return objClass1 which should be a object of class class1
hope now its clear,
Thanks,
Best Regards,
