But, having done that successfully, it also does something BK> it shouldn't do: throws an exception: This seems to be something about IE. In FAQT there is an article about using DDE to run IE http://www.faqts.com/knowledge_base/view.phtml/aid/1360/fid/244 BTW, I found the source for the dde module (Via Mr Chris Tismer's site for Pirx; http://starship.python.net/crew/pirx/). I'm not absolutely sure that this is the source used in ActivePython, but I bet that if it isn't someone will be nice and tell us ;-) The source can be downloaded at: http://starship.python.net/crew/pirx/win32/dde.zip This source seems to be based on the "Implementing DDE Using C++ Classes" by Mr Nigel Thompson. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndynex/html/msdn_ddeserv.asp There are also some references to Q92829 in the KB. Anyway, One possible reason for the exception in IE could be that the DDE timeout has be set to 5 seconds. If IE doesn't say it's ready within 5 sec then you will get an error/exception. If you want to use DDE in some 'real' application you should look up asynchronous use of DDE. A Real good site is RHA (Minisystems) "Dynamic Data Exchange (DDE) and NetDDE FAQ" I hope that this info will get you on your way and Please document your movements through DDE territory using Python. -- Best regards, Anders mailto:[EMAIL PROTECTED] _______________________________________________ ActivePython mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs Other options: http://listserv.ActiveState.com/mailman/listinfo/ActivePython
