Wait! recv() can return 0. This can mean only one thing: the remote side has closed the
connection on you! A return value of 0 is recv()'s way of letting you know this has occurred.

Ok.. I found and replaced all CViews with CEditView. And it's not asserting now. Is it a right way?

On Opening a document, I read the text and keep it in a variable

You should probably do that in the OnUpdate handler - that should get called when the document is updated, by the document calling its UpdateAllViews method (that's part of CView).

public:
   CString const& GetText() const { return text_; }
protected:
   CString text_;

void CdddDoc::Serialize(CArchive& ar)
{
   if (ar.IsStoring())
   {
      ar.Write(text_, text_.GetLength());
   }
   else
   {
      const UINT fileSize = (UINT)ar.GetFile()->GetLength();
      CStringT<char, StrTraitMFC_DLL<char> > byteString;
      ar.Read(byteString.GetBufferSetLength(fileSize), fileSize);
      text_ = byteString;
      UpdateAllViews(0);
   }
}

void CdddView::OnUpdate(CView* /*pSender*/, LPARAM /*lHint*/, CObject* /*pHint*/)
{
   SetWindowText(GetDocument()->GetText());
}

The void CMyTestView::OnFileOpen()
{
 ..

}

BOOL CMyTestDoc::OnOpenDocument()
{
	return TRUE;
}

1.
void CMyTestView::OnFileOpen()
{
   //Load the file path of the selected file.
}

2.
BOOL CSDITestDoc::OnOpenDocument()
{
    return true;
    //Call Serialize()
}

3.
void CSDITestDoc::Serialize(CArchive& ar)
{
 // read the file
 //Update view.
}

But shouldn't that be view's OnFileOpen

• An application has zero to many documents
• Each document is related to precisely one application, but can have one to many views
• Each view is related to precisely one document
