How to dynamically link LotusNotes object irrespective of the Notes client verison.

Question

Hi,

I am using Interop.domino.dll in my application created in c#.NET to access the NSF files.

I am doing static binding like :

NotesSession _lotesNotesSession = new NotesSessionClass();
object obj = Activator.CreateInstance(
      Type.GetTypeFromProgID("Notes.NotesSession"));                
_lotesNotesSession.Initialize(nsfPassword);

I have lotus notes 8.5 ver installed on my pc. The problem is like : It runs only for the 8.5 version of lotus notes and for the rest version it doesn't work.

Can we have some other alternative to solve this issue, such that it work for all teh versions.

please provide me some help.

Thanks in advance.
