unable to get the excel app event trigger for for window resize
 

I am working on a Excel addin coded in C#.
Bascially the addin connects to a database , fetches data and if there
are any errors , then the errors are logged to a event log type dailog
application, and the data fetched is populated to excel.

Now the need is to minimize the event log type application whenever
excel main application is minimized.

I have tried some of the WindowResize events but they are raised only
when the workbook inside the excel is minimized but if the user
mimimizes the excel app it is not fired.

Would like too know if this is achievable? thanks.
