The reason I was asking is, that after some Googling, the best hint regarding the problem I came up with is: "Apparently in Excel 12 (Excel 2007) the RTD callback object that implements dual IRTDUpdateEvent interface throws exception (generic COM exception 0x80020009) when is called via IDispatch. If you use v-table binding the call to UpdateNotify succeeds. I don?t really know whether it is a bug in Excel 12 or a feature." http://www.nevaobject.com/phpbb3/viewtopic.php?t=516 Anyway, due to time constraints I moved on to C# and ExcelDNA to implement my stuff. Originally, I wanted to prototype in PyWin32 ... which is absolutely great nevertheless! cheers, Tobias _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
