Ashwani,

First there is no need to create an edit control for your view. When you create you MFC application the wizard will allow you to change your view type (step 6) to either a CEditView or a CRichEditView depending on your requirements. If you create your application using the CEditView you can then use the following code in the Serialize method of the document.

((CEditView*)m_viewList.GetHead())->SerializeRaw(ar);

This should solve your problems.
