Office documents integration with Sharepoint

Hi,

I am saving the opened Word/Excel/PowerPoint to SharePoint Document Library using Addin express and web service created in SharePoint environment and hosted there itself. Now my requirement is to replicate the "Save and Send"functionality in office documents.

In"Save and Send" after saving the document to Document library the local document maintains connection to Sharepoint document library, so any changes afterword are saved to the uploaded document itself.

So how could I achieve this in my application, I can save the document to Document Library and now require that the uploaded document should be displayed not the local document like it is with "Save and Send" button click.

Please suggest, Thanks in advance.
