Dim directory As DirectoryServices.DirectorySearcher
Dim result As DirectoryServices.SearchResult
Dim email As String
email = Dts.Variables("email").Value.ToString
Try
directory = New _
DirectoryServices.DirectorySearcher("(mail=" & email & ")")
result = directory.FindOne
Dts.Variables("name").Value = _
result.Properties("displayname").ToString
Dts.Variables("title").Value = _
result.Properties("title").ToString
Dts.TaskResult = ScriptResults.Success
Catch ex As Exception
Dts.Events.FireError(0, _
"Script Task Example", _
ex.Message & ControlChars.CrLf & ex.StackTrace, _
String.Empty, 0)
