How to connect Active Directory using LDAP? The code should work in ASP and ASP.Net.
Thanks for your help.

public bool AuthenticateUser(string domain, string username, string password)
{ string LDAPPATH ="LDAP://appserver.com";
string domainAndUsername = domain + @"\" + username;
DirectoryEntry entry = new DirectoryEntry( "LDAP://appServer.com", domainAndUsername, password);
try
{
// Bind to the native AdsObject to force authentication.
Object obj = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=" + username + ")";
search.PropertiesToLoad.Add("cn");
SearchResultCollection result = search.FindAll();
if( result.Count==0)

Hi Himabindu,
Thank you for your code, but what I need is the code should work in both ASP and ASP.Net. Without using directory services it should work in both.
for ex. in ASP
strADsPath = "LDAP://strservername/DC=xxx,DC=com"
Set objldap = GetObject(strObjectADsPath)
objldap.GetInfo
above code will work in ASP but how to execute same code in asp.net

I get this error: "Invalid attempt to FieldCount when reader is closed." on the databind() method when the following code is run:
Private Sub loadProject()
Dim objDR As SqlDataReader
Dim objConn As New SqlConnection(strConn)
Dim objSQL As New SqlCommand("SELECT * FROM Projects ORDER BY Priority DESC, ProjectID DESC", objConn)
objConn.Open()
objDR = objSQL.ExecuteReader
grdDisplay.DataSource = objDR
grdDisplay.DataBind() <--Error occurs here
If grdDisplay.Items.Count = 0 Then
grdDisplay.Visible = False
lblMessage.Text = "No projects found."
Else
grdDisplay.Visible = True
End If
objDR.Close()
objConn.Close()
End Sub
This code is called directly from the Page_Load event on the first page after login so there are no prior database calls that could close the connection. When I step through the code in VS the autos window shows the objDR IsClosed property is FALSE at the time the databind() method is called.
This same code (different SQL strings) works fine everywhere else in the app. Also it has been working fine all along and just simply stopped working. The only change I made was moving the database and thus adjusting the connection string (which works fine elsewhere.
What am I missing?
Thank you in advance for any suggestions!

Try this.
Private Sub loadProject()
Dim objDR As SqlDataReader
Dim objConn As New SqlConnection(strConn)
Dim objSQL As New SqlCommand("SELECT * FROM Projects ORDER BY Priority DESC, ProjectID DESC", objConn)
objConn.Open()
objDR = objSQL.ExecuteReader
grdDisplay.DataSource = objDR
grdDisplay.DataBind() <--Error occurs here
objDR.Close()
objConn.Close()
If grdDisplay.Items.Count = 0 Then
grdDisplay.Visible = False
lblMessage.Text = "No projects found."
Else
grdDisplay.Visible = True
End If
End Sub

Thanks for the suggestion - however I still get the same error. This error occurs on both my development laptop, and on my internal test server.

How is your grid set up? I bet you are attempting to bind to columnName not returned in your query. Remember the fieldnames are case sensitve. Also, try not using * but rather listing the fields.

Thanks! You forced me to review the datagrid setup and of course I realized that I have an embedded datagrid that lists project tasks, and of course it was throwing the error, not the parent datagrid().

I use MS Studio to coding the asp.net, i need to perform some action if the user close the web page, i try page_unload before but cannot function. So, may i know where i should put my code for the coding page, when the user close the page and some action fired?

The page unload is the event on the code behind not the client. You can't really run server code when the browser closes. You can however, run code in the global.asax for the Session_End event.

Well you can call some server-side code using AJAX in the onBeforeUnLoad

This is a difficult one. You can add a javascript function to the body (onunload). The only problem you have is that this function will fire before postback as well. You will have to pull some trick of setting a javascript variable that controls the function.
You won't be able to do server side processing, because the page will not do a request when you close it. Well I think so. If that is wrong, can someone please correct me.

Hi this is more a question about appearance than anything. I have a check box list which I want to divide up as follows. 3 Items followed by a heading followed by another 3 items heading and so on. But all the items are the same list. Can this be done? Thanks in advance

You need to be a little creative. I would suggest creating a user control formatted the way you want. Then pass the user control the heading and dataset (3 records). Use the loadcontrol option to dynamically add them to your page. Or have a dropdownlist that filters the checkbox.

String.Format("{000:N}", maxNumberFound)
maxNumberFound is = 3
and I want it to display as "003".
anyone know how without string manipulation.
Thanks,
Nick
1 line of code equals many bugs. So don't write any!!

Yeah I used ToString to format it.
I tried deleting it, but could find the topic.
Thanks tho

Did you already resolve this?
If not, try this:
String.Format ("{0:D3}", maxNumberFound)

actually yes.

Unfortunately, that just returns "3.00" I used d5.
But the ToString has an override that I can say "000" and it will form correctly.
Thanks for helping tho.

That's weird. Maybe it's a difference of UI cultures that causes that. On my system it returns "003".
Oh well. Glad you got it sorted.

This might help you[^].
You will still need to get rid of the browser menu so that the don't go to View / Page Source.
