Ok, thanks! Looks like these are the names to use instead:

IE.ExecWB(
   constants.OLECMDID_SAVEAS,
   constants.OLECMDEXECOPT_DONTPROMPTUSER,
   filename,
   None)

Altough the ...DONTPROMPTUSER option doesn't work - the Save As dialog  
always appears. Some kind of permission or safety measure, I presume.

My original intent was to save the file using the .mht format, but that  
format is not listed on the Save As dialog. I'll investigate using  
IMessage.CreateMHTMLBody but that's a different topic.
