I've found Chip Pearson's article about activating Excel from another
application

http://www.cpearson.com/excel/ActivateExcelMain.aspx

so I'm thinking I can do this. When I look at the list of Window Class
names, I see that NetUIHWND is used for PowerPoint 2007, Word2007 and
Access2007. How does it know to find PowerPoint over Word?

Thanks,
