Question

Getting value from a COM object

Asked by: frodoman

I'm trying to pull from active directory the date of user's last password change but when I try to display the value I get a result of: System.__ComObject

I know nothing about .net interaction with com so I suspect it's something obvious.  The relevent code I'm using is:

Dim objGroupEntry As DirectoryEntry
objGroupEntry = objResult.GetDirectoryEntry()
Response.Write(objGroupEntry.Properties("pwdLastSet").ToString)

Any help would be appreciated - this is .Net 2.0.

Thanks for the response.  I converted that to vb.net (what I'm using) and tried this:

Response.Write(CType(objGroupEntry.Properties("pwdLastSet").Item(0), Int64).ToString)

This returns an error: Conversion from type '_ComObject' to type 'Long' is not valid

I've got it now - after hours of searching I found the answer on the web right after posting here.  Figures...

For future readers, the key is casting the property to ADSLargeInteger  (must import ActiveDs) then calculating the number of milliseconds elapsed and converting to a date from there.  Sample code below:

            Dim LargeInt As IADsLargeInteger = objGroupEntry.Properties("pwdLastSet").Item(0)
            Dim FileTime As Long = LargeInt.HighPart * 4294967296 + LargeInt.LowPart
            Response.Write(DateTime.FromFileTime(FileTime).ToShortDateString & "<br>")

hammdan - I appreciate you taking the time to respond.  Your link didn't really contain the answer however I used some of the terms in the link as search terms to eventually find it so I'm going to award you a minimal grade for your efforts.
