getting the PwdLastSet attrib value though .net

Hello there
I need to get the "PwdLastSet " of a user object to know when he last set his
password.
I am using DirectoryServic es.DirectoryEnt ry to bind to the user object, but
it either gives "Argument 'Prompt' cannot be converted to type 'String'." or
when I use .tostring it returns "system._comobj ect"
I even tried to use this line but it also failed
dater.FromFileT imeUtc(entry.Pr operties("pwdla stset").Value) 'ast from
type '_ComObject' to type 'Long' is not valid.
I use the code below:
Dim entry As New DirectoryServic es.DirectoryEnt ry
entry.Path = "LDAP://cn=sameh
ahmed,ou=infras tracture,ou=mas reya,dc=masreya ,dc=local"
MsgBox(entry.Pr operties("homed irectory").Item (0).ToString) 'works fine
MsgBox(entry.Pr operties("pwdla stset").Item(0) .ToString) 'returns
"system._comobj ect"
MsgBox(entry.Pr operties("pwdla stset").Value.T oString) 'returns
"system._comobj ect"
MsgBox(entry.Pr operties("pwdla stset").Value) 'returns "system._comobj ect" '
"Argument 'Prompt' cannot be converted to type 'String'."
Any ideas?
Thanks in advance

I think the pwdlastset attribute is a concatenated version of two distinct
dates. I did a quick search for pwdlastset and came across this vbscript
block. You can get some ideas from this.

There are basically two ways to get the Int64 value you need.

If you use the DirectorySearch er, it marshals AD INTEGER8 types to .NET
Int64 automatically, so no work needs to be done. This is by far the
easiest way.

If you use the DirectoryEntry, it marshals the value as an ADSI
IADsLargeIntege r type, which at runtime is a System.__ComObj ect. This is
annoying, but you can get the value with a little interop and some data
munging. This works for me:

dim entry as new DirectoryEntry( "LDAP://yourdn here")
dim pwd as object = entry.Propertie s("pwdLastSet") .Value
dim pwdDate as DateTime
pwdDate = DateTime.FromFi leTimeUtc(GetIn t64FromLargeInt eger(pwd))

Function GetInt64FromLar geInteger(byval largeInteger as Object) as Int64

dim low as int32
dim high as int32
dim valBytes(7) as byte

dim longInt as IADsLargeIntege r = Ctype(largeInte ger, IADsLargeIntege r)
low = longInt.LowPart
high = longInt.HighPar t

BitConverter.Ge tBytes(low).Cop yTo(valBytes, 0)
BitConverter.Ge tBytes(high).Co pyTo(valBytes, 4)

Return BitConverter.To Int64(valBytes, 0)

End Function
<ComImport(), Guid("9068270b-0939-11D1-8be1-00c04fd8d503"),
InterfaceTypeAt tribute(ComInte rfaceType.Inter faceIsDual)> _
public interface IADsLargeIntege r
property HighPart as int32
property LowPart as int32
end interface

Note that you can also get the high and low values via reflection and late
binding or by importing the activeds.dll COM object into .NET.

Note that the DateTime you get back will be in Utc, so if you need local
time, make sure you call ToLocalTime.

Dear Joe
Thanks for replying
as i am totaly new to the develeopment field i tried to understand the code
that you sent.
But after a long time i decided to copy it to my form and see what happens
this part (that i failed to understand)
<ComImport(), Guid("9068270b-0939-11D1-8be1-00c04fd8d503"),
InterfaceTypeAt tribute(ComInte rfaceType.Inter faceIsDual)> _
Public Interface IADsLargeIntege r
Property HighPart() As Int32
Property LowPart() As Int32
End Interface

fails with the following errors:

Attribute cannot be used on 'IADsLargeInteg er'.
Type 'ComImport' is not defined.
Type 'InterfaceTypeA ttribute' is not defined.

i would rerall appriciate it if you tell me what i should do .
thanks again

You need to import the System.Runtime. InteropServices namespace in order to
get those attribute definitions.
