How to cancel work in Interop.excel? C # - creating add-ons in VS
I assume the following:
- I register an undo method on the stack (implemented by me).
- I keep the current state ... where?
When the user uses cancel (ctrl-z), my call is canceled, and I restore the previous state with the data I saved.
It is impossible to get good information about this. Maybe this works completely differently?
