Hi Jason yes, calling ReleaseComObject does the job.
however, I'm just concerned to find out why the Garbage Collection doesn't work in the first example, but does in the second. Regards Howard. -----Original Message----- From: Jason Bock [mailto:[EMAIL PROTECTED]] Sent: 20 May 2002 16:39 To: [EMAIL PROTECTED] Subject: Re: [DOTNET] strange behaviour with Garbage Collector >does anyone have any ideas on the following: > >if I try this: > >Excel.ApplicationClass appClass = new Excel.ApplicationClass(); >appClass = null; >GC.Collect(); > >Excel.exe remains open as a Process in Task Manager. Have you tried this: Excel.ApplicationClass appClass = new Excel.ApplicationClass(); // Use appClass... Marshal.ReleaseComObject(appClass); appClass = null; This will release the COM object reference (at least it should).
