I can use DDE with Excel on XP with TOS and DDE on OOo Calc on XP with TOS. I can use TOS on Ubuntu 9.10, but I can't get DDE on OOo Calc spreadsheet to work on Ubuntu. Is it possible? =TOS|LAST!SPY =DDE("TOS";"LAST";"SPY")
That's pretty darn ambitious. I wouldn't rely on DDE on any non-Windows platform. Even if it worked, I'd be suspicious about reliability/stability.
