Transfer data from 1 view to another

I'm trying to load data into a buffer from 1 view and send to to a document, then to another view for editing.  WHat's the appropriate way to do so?

This is a split window application with 2 views.  Basically view 1 reads data from a file to a buffer.  I know how to send it to the document, but how can the document inform view 2 that there is new data to display?  View 2 is a richedit control, and I want to set the text with something like:

pRich->SetWindowText(buffer)

Thanks,  Veronica

Use the built in Doc View communication in MFC. Something like this...

// In View1
// (Assuming you have already sent the
// data to the document)

GetDocument()->UpdateAllViews(this);

// This causes OnUpdate to be called in
// all views...

// In View2
void CView2::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint)
{
  if (pSender && pSender->IsKindOf(RUNTIME_CLASS(CView1)))
  {
    // View1 is signaling new data has arrived.
    // Use GetDocument() to get a pointer
    // to the doc, you can then access the data
    // directly.
  }
}
