Unhandled Com exception on Workbook.Save()

Aspose.Cells Product Family
1

Hi, I am evaluating Cells .Net in a CCW called from unmanaged code. I have found that an unhandled exception in my C# code will cause a Com exception but that I can add try/catch code and it gets caught within my C#code. However if I save to a file that exists but is in use by Excel, I get a Com exception that does not get caught.

I expect an exception of some kind in this situation but I need to be able to catch it within my C# code.
Thanks,
