Mark 1, 6 36 You cannot handle ThreadAbortException so no need to catch the exception. The Unload event occurs before the Close event.

Load and unload device drivers

Note When you create macros or event procedures for events related to the Unload event, such as Deactivate and LostFocusbe sure that they don’t conflict for example, make sure you don’t cause something to happen in one macro or procedure that is canceled in another and that they don’t cause cascading events.

You can, in effect, catch a ThreadAbortExceptionby issuing a Thread. You may also leave feedback directly on GitHub.

The reference count is also incremented by a call to LoadLibraryEx unless the module is being loaded for the first time and is being loaded as a data or image file. Sign in to give feedback. Simply not calling FreeLibrary for that DLL allows the application to close successfully, but my assumption is that the FreeLibrary call is important.
