You can disable or read only your control(Richedit) with set these opition (disable or readonly) on the property window of control.

Does it need to be read-only all of the time? If so, do that in the resource file rather than at runtime via SetReadOnly().

Use MoveWindow or SetWindowPos

I tried this:

void CTextView::OnSize(UINT nType, int cx, int cy)
{
CFormView::OnSize(nType, cx, cy);
m_RichEdit.SetWindowPos(this, 0, 0, cx, cy, SWP_NOMOVE);
}

program will not start beacuse i get some message. I think the problem is in "this" in SetWindowPos. My base class is CFormView. Any ideas?

That may be due to the following reason.

m_RichEdit will not be subclassed when OnSize is called for the first time. This usually happens in the dialog based applications.

In your case, you can do as...
GetDlgItem( IDC_RICHEDIT )->SetWindowPos(this, 0, 0, cx, cy, SWP_NOMOVE);

Hope it will work...

One thing i ignored... Frown | :(

Why are you passing the "this"? It is not needed. You can set it as NULL and modify it as ( 0, 0, 0, cx, cy, SWP_NOZORDER | SWP_NOMOVE )

This is safe:

void CTextView::OnSize(UINT nType, int cx, int cy)
{
    CFormView::OnSize(nType, cx, cy);

   if (m_RichEdit.GetSafeHwnd())
      m_RichEdit.MoveWindowPos(0, 0, cx, cy);
}

cannot convert parameter 1 from 'struct HWND__ *' to 'const class CWnd *'
this is the message I get when I try your solution.
Grhhhhh.... This is driving my crazy......

I'm sorry - it was my mistake - I didn't delete the "Pos" when I changed the
SetWindowPos to MoveWindow Blush | :O

void CTextView::OnSize(UINT nType, int cx, int cy)
{
    CFormView::OnSize(nType, cx, cy);

   if (m_RichEdit.GetSafeHwnd())
      m_RichEdit.MoveWindow(0, 0, cx, cy);
}
