First off, let me say this is a really nifty app - I like it a lot.
I want to put something similar into a VB.NET (VB 2008 Express) app that I'm building for internal use. I've gotten almost everything from this to work. The one place I'm having trouble is figuring out how you assign the images to the different nodes. I see the code for selecting an image based on the object type, but where does it get the source images?
Please bear with me if this is an obvious question, but I'm new to forms programming and don't have listview/treeview controls nailed yet. Add to that I don't know C# at all - that's why I'm building in VB not C#.
Thanks for your help, and for a great app!

Ok, this is actually quite simple. The enum AdImages refers to indexes in the ImageListimageList_adObjects. Basically AdRoot=0 which is the first image in the image
list. Then depending on the object category/SchemaClassName I put a specific image.

Thanks for the quick response, particularly when the original post was so long ago!
I was able to follow the enum AdImages/assign by object category logic. What I don't see is how/where you're populating imageList_adObjects. I'm using Visual C# 2008 to view the project - I don't know if maybe in the conversion process it hid something from me?

Doh! Just figured it out. Tunnel vision is a terrible thing - just found the imagelist control in the bottom of the designer window. I think I've got it now. Thanks for your help!

It is quite simple to do that.
Do you want to display user attributes on the right side when you select a user?

Thanks for your reply Sven So. Yes i need to display user properties[attributes] in the format of tree stucture.

Where did you get your bitmaps for the objects? Did you create them yourself? I'm creating a browser for my application and want to use the standard AD icons for the objects.

Hey,
just download the freeware program resourse hacker from:
http://www.users.on.net/johnson/resourcehacker/
Then you can extract icons (save as ico files) from dll's and exe files like explorer.exe, iexplore.exe and others. After that you can just import the ico files into your imagelist within Visual Studio and use them in your project.
Good luck  , Sven

Maybe you did not realize it, but Windows (and the rest of the MS programs) is not Open Source. This means you can NOT just use any icon/graphic from Windows you like.

Of course if you sell the product, than you are really stupid. But if you use it inhouse or for your personal development I dont see it as such a big issue.
We actually have quite good contact to Microsoft and I developed a rich management interface that uses the Browser functionality and Microsoft icons and they really like it. Basically its build with Microsoft Technology, why shouldnt they like it.
Thanks for your important comment anyway. Of course its valid.

I am trying to get all machines in my active directory, but if I supply rootDSE in the binding, I only get machines from the domain that I am logged in to. Here is my set up:
we have DOMAIN, which I am logged in to, then we have DOMAIN.SUBDOMAIN. With rootDSE, I can only get machines in DOMAIN. I can get the machines form DOMAIN.SUBDOMAIN if I specify SUBDOMAIN in the binding (LDAP://SUBDOMAIN).
Any suggestions on how I would get machines from both the Domain and the subdomain?
Thanks
Steve

You mean instead of having one topNode in the TreeView, you want to have severals.. He should probably by default find out, if there are any child domains. Shouldnt be any problem to implement. I can take a look if you want.

I haven't been able to figure out how to do it with the DirectoryServices namespace so I decided to go down and dirty and get it using WinAPIs, I did not place any error handling on this so you will have to do this. Also if you need more info on return values I included a few links on the remarks and comments to help you out. This should be able to return all of the Domain Names in LDAP Format (e.g. dc=domain,dc=ext) for all domains registered in your Global Catalog Server, Also since I'm repeating the process for every site you might need to look for duplicated entries in the DomainNames string array. Good Luck

Hey Joseph,
I know what the problem is. Need to find some time to fix it. Give me until next week.

This still doesn't seem to be working.

We use AD not LDAP, so If I replace your LDAP:// with WinNT:// it should ideally work fine. However I am having problems resolving the proerty defaultNamingContext in WinNT. Any suggesstions? Also, I am putting in a known domain name should I be entering the forrest name instead?
Thanks. dom

If you use AD (Active Directory) than it should just work fine, because its made for it. ADSI (Active Directory Services Interface) supports 2 providers one is LDAP, which you could also use to connect to other LDAP directories (Active Directory is also an LDAP directory). Winnt is mainly used to connect to NT4 domains, but can still be used to access Active Directory for backwards compatibility. In your case Winnnt doesnt has such property defaultNamingContext. If your computer is in Active Directory and you are logged on with a user from AD my example should just work fine. With the call to the rootDSE he will get information about your AD domain, and then in the second call connect to AD with defaultNamingContext, e.g. "dc=test,dc=com". Just try the example without changing anything. Please come back, if it still doesnt work for you.

Thanks. I guess it has to be on a machine that is in the directory... even when I supply it a domain, username and password. Thanks for the help. I noticed a bug in your app though... If you highlight one node, then go to another, then go back to the orignal, you get duplicate child nodes.
Thanks,
Dom

Yes I see the bug now. Small thing. In the AfterSelect method I just added a e.Node.Nodes.Clear(); Its a simple workaround, in a real application, you would not want to reload the stuff all the time. You want to refresh by F5 or a context menu. Could be added later. Thanks for your findings.
