SUMMARY

This article contains a Microsoft Visual Basic code sample that demonstrates how to programmatically retrieve the properties of a User object with Active Directory Service Interfaces (ADSI) and ActiveX Data Objects (ADO).

MORE INFORMATION

The following sample code demonstrates how to identify the Lightweight Data Access Protocol (LDAP) properties that are displayed by the Users and Computers snap-in when you view the User object's Exchange General and Exchange Advanced tabs.

To create and run the sample program, perform the following steps:

1. Create a new Visual Basic project called Project1.vbp.

2. Paste the following code in the code window:

   Sub Main()
   
   Dim oRootDSE As IADs
   Dim oDomain As IADs
   Dim obj As IADs
   Dim objUser As IADsUser
   Dim dacl As IADsAccessControlList
   Dim ace As IADsAccessControlEntry
   Dim oConnection As New ADODB.Connection
   Dim oCommand As New ADODB.Command
   Dim RS As ADODB.Recordset
   Dim RS2 As ADODB.Recordset
   Dim strQuery As String, strAlias As String, mystring As String
   Dim varDomainNC As Variant, Desc As Variant, varReports As Variant
   Dim PropArray As Variant, Prop As Variant, DescList As Variant
   Dim Everyone As Boolean
   Dim i As Integer

   Const RIGHT_DS_SEND_AS = &H2
   Const RIGHT_DS_PRIMARY_OWNER = &H4

   Set oRootDSE = GetObject("LDAP://RootDSE")
   varDomainNC = oRootDSE.Get("defaultNamingContext")

   oConnection.Open "ADs Provider"
   
   ' Build the query to find the user based on their alias.

   oCommand.CommandText = strQuery
   Set RS = oCommand.Execute
   If RS.RecordCount = 0 Then
       Debug.Print strAlias, " is not a valid email alias"
