wordApp = Microsoft.Office.Interop.Word.ApplicationClass;

This line creates an instance of Microsoft Word, as can be observed by looking at the Windows Task Manager: the process WINWORD.EXE appears in the list. The line

wordApp.Quit()

close the application, and the WINWORD.EXE process disappears.

Now suppose the first line is called within a function, but not the second, and the handle wordApp is not returned by said function. Is there any way to retrieve a valid handle to the object instance, which still remains?

Just in case others come across this question ... the "obvious" solution is to make wordApp a property of a custom handle object, and to do wordApp.Quit() in the destructor of the object.

I was hoping for a non-object based approach, however, so if anybody has any insight, please let me know. Like maybe a way to find an existing instance of Microsoft.Office.Interop.Word.ApplicationClass.
