I'm attempting to read a couple of Active Directory field values (fields are distinguishedName & Description) using the Microsoft.Visual Basic Class. However, I had two sets of code I merged (one set of code had Option Strict On and the other one I forgot to turn on) caused some errors to come up.
I received the error "Option Strict On prohibits operands of Type Object for Operator '&'" on this line of code: --> objRecordSet.Fields("distinguishedName").Value) <--     and then I received this error, "AccountDisabled is not a member of 'ADODB.RecordSet'." on this line of code: --> If objAccount.AccountDisabled Then <--.
Please see code snippet below. I would appreciate any assistance on which Classes/Methods or Properites to use NOW that I've implemented Option Strict On for all the code.
Many Thanks,
WD

Ok, after making changes 40 ways from Sunday, my code now looks like this but I haven't tested it yet and I'll explain why in just a moment. Even thought I've changed this line of code, --> Dim objAccount As ADODB.Recordset = CType(GetObject("LDAP://" & CStr(objRecordSet.Fields("distinguishedName").Value)), Recordset)", <-- I still end up getting the error "AccountDisabled is not a member of 'ADODB.RecordSet'". How could a member of the ADODB.RecordSet be there one minute, but then not be there just by adding the Option Strict On for type safe language. I've already checked the methods and properties after setting Option Strict On and there is no "AccountDisabled" property. Is there another Class that I can use as its equivalent?

Let's move to something a bit more modern and  use the built in DirectoryServices namespace.   http://msdn.microsoft.com/en-us/library/system.directoryservices.directoryentry.aspx

Unfortunately, the DirectoryEntry class doesn't directly support the AccountDisabled property.... instead you'd have to check to see if the UserAccountControl property as a bit set.   Below is an example

Imports System.directoryservices

        Dim de As DirectoryEntry

        de = New DirectoryEntry("LDAP://" & objRecordSet.Fields("distinguishedName").Value.ToString)
        if CBool(Cint(dir.Properties("userAccountControl").Value) And &H2) then

Graye,
Is there another Object I can use vs. the Dir in the line of code that reads "(dir.Properties("userAccountControl").Value) And &H2) then"??
I'm getting an error message saying that "Properties is not a member of String" or the String "dir".
Thank you for your assistance.

To provide some additional insight, my objective here is to determine whether or not the distinguisheName (i.e. the Computer object) and the Description field contains the Value = DISBL in Active Directory and then perform If...Else... operations based on those conditions.
