Comments on: Kill dozens of Excel.exe processes stacking up in Task Manager http://www.ocxt.com/archives/133 ActiveX document container for hosting Office documents and PDF (including Adobe PDF, Microsoft Word, Microsoft Excel, Microsoft PowerPoint, Microsoft Project and Microsoft Visio documents) Sat, 19 Nov 2011 03:49:30 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: office viewer http://www.ocxt.com/archives/133#comment-134 office viewer Tue, 08 Dec 2009 03:03:04 +0000 http://www.ocxt.com/?p=133#comment-134 This is because ExcelIS COM and COM does not have the easy garbage collection that comes with Java/.NET. Each COM object uses a Reference Count and until the reference count is 0, the COM object will never get out of your RAM. So how then do you reduce the reference count to 0. By setting every COM object reference to NULL. This is not only the Document and Application. You can overload the BeforeDocumentClosed event. OA1.ActiveDocument.Close(); OA1.ActiveDocument = NULL; OA1.Application.Quit(); OA1.Application = NULL; Or try the Garbage Release. public void OnDisconnection(Extensibility.ext_DisconnectMode disconnectMode, ref System.Array custom) { Trace.WriteLine("OnDisconnection"); System.Runtime.InteropServices.Marshal.ReleaseComObject(applicationObject> applicationObject =null; GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); } This is because ExcelIS COM and COM does not have the easy garbage collection that comes with Java/.NET.

You can overload the BeforeDocumentClosed event.

OA1.ActiveDocument.Close(); OA1.ActiveDocument = NULL; OA1.Application.Quit(); OA1.Application = NULL;

Or try the Garbage Release.
public void OnDisconnection(Extensibility.ext_DisconnectMode
disconnectMode, ref System.Array custom)
{
Trace.WriteLine(“OnDisconnection”);
System.Runtime.InteropServices.Marshal.ReleaseComObject(applicationObject> applicationObject =null;
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
}
