>MAPI.Session and MAPI.Message (Active Messaging or CDO - Collaboration Data Objects) could be used to prepare the mail message, attachments and use SEND() method. After that, the same window opens, but already with attachments. I guess Excel 2000 uses that way (or even uses the API functions for appropriate DLLs?). Probably, using Java Script yuo can invoke these objects and do the same.

It cannot be MAPI object automation, because it is with Outlook Express, that is, according to docs, doesnot "support" automation.
So, the only thing I can think of is MAILTO:, or ... MAPI32.DLL direct calls.
