Put focus on a tab in Lotus Notes

Hi and thanks for all responses in advance.

We are developing a DLL written in C# which handles communication between a Lotus Notes application and another external application.

The Lotus Notes application (plain NSF) is running but the focus might be on another tab in the client and I need to put the focus on my application tab.

I have used the following methods to try this:

  1. OLE

  2. Notes URL

  3. NDL link file

The problem is that in most cases Lotus Notes will open a new instance of the Lotus Notes application - but it should be checking if the application is running and focusing on it. So I assume this is a Notes “feature”.

Does anyone know another method to put the focus on a tab?

PS. I’m posting this in both Lotus Notes 8 (8 and 8.5)forums.
