Hello Bhimasena,
From your post, my understanding on this issue is: your excel.exe is notterminated when you close the Excel, due to a event handler in your add-in.
You have already tried the method: ReleaseComObject and followed the kb
article: http://support.microsoft.com/kb/317109, but it did not help. If
I'm off base, please feel free to let me know.
Because you said that the add-in runs well for Word, would you let me know
whether the event handler also runs in Word? What is that event handler
for? Would you send me some sample codes so that I can reproduce the issue
on my side?
Besides, based on my experience, my guess is that :
1. a circular reference of objects result in your problem. For instance,
your Application object has a reference to a delegate holding a reference
to the event handler, and the event handler also has a field which can
optionally point back to the Application object. Such a circular reference
may cause that the Application object cannot be released even if you call
ReleaseComObject. Please check it and let me know if there does exist a
circular reference in your code.
2. some additional references are created in your event handler but you do
not notice them. For instance,
oBook = oExcel.Workbooks.Add() will create an additional reference to
Excel.Workbooks object. Thus it should be modified as
dim oBooks as Excel.Workbooks
oBooks = oExcel.Workbooks
oBook = oBooks.Add()
and finally release the oBooks with oBooks = Nothing
