Hello, friends,

I am using Excel in our C#.net applicaiton. I need to catch the events when
the launced Excel window gets focus. I tried

AppEvents_WorkbookActivateEventHandler
AppEvents_WindowActivateEventHandler

It worked fine when more than one .xls files were opened and I switched
between those Excel windows. However, it did not worked when there was only
one open .xls file and I switeched between this Excel window and other apps,
for example, after using IE, I came back to the Excel, non of the above
events fired.

How to get around this problem since I really need to catch this event? Any
ideas?

Thanks a lot.
