lastLogonTimeStamp and Vb.net and Active Directory

If anyone has an example of this I'd appreciate seeing it.
I'm having a problem with assigning the value of an object's
lastLogonTimeStamp property to a variable. I can do it with VbScript, but
can't get it in .Net.
The value is 64 bit. I'm trying to assign it to a Long variable.


dateLastLogon =
mySearchResult.GetDirectoryEntry.Properties("lastL ogonTimestamp").Value


The above line doesn't work, but the below line does. The error I get is:
"An unhandled exception of type 'System.InvalidCastException' occurred in
microsoft.visualbasic.dll
Additional information: Cast from type '_ComObject' to type 'Long' is not
valid."


lstComputers.Items.Add(mySearchResult.GetDirectory Entry.Properties("Name").Value)


Any ideas? If more info is needed, let me know.

TIA

PS, I just posted some code showing how to do this... now if you could
tell me how to convert the value to something readable, like a datetime
value, that would help. I can only find examples in vbscript which
won't work in vb.net!
