Excel automation: Close event missing
- by chiccodoro
Another hi all,
I am doing Excel automation via Interop in C#, and I want to be informed when a workbook is closed. However, there is no Close event on the workbook nor a Quit event on the application.
Has anybody done that before? How can I write a piece of code which reacts to the workbook being closed (which is only executed if the workbook is really closed)? Ideally that should happen after closing the workbook, so I can rely on the file to reflect all changes.
Details about what I found so far:
There is a BeforeClose() event, but if there are unsaved changes this event is raised before the user being asked whether to save them, so at the moment I can process the event, I don't have the final file and I cannot release the COM objects, both things that I need to have/do. I do not even know whether the workbook will actually be closed, since the user might choose to abort closing.
Then there is a BeforeSave() event. So, if the user chooses "Yes" to save unsaved changes, then BeforeSave() is executed after BeforeClose(). However, if the user chooses to "Abort", then hits "file-save", the exact same order of events is executed. Further, if the user chooses "No", the BeforeSave() isn't executed at all. The same holds as long as the user doesn't click any of these options.
