How to check ENTER was pressed in edit box?

How to determine when user press ENTER "in" single line edit box ?:

control = CreateWindow( "EDIT", NULL, WS_CHILD | WS_VISIBLE | WS_BORDER,
        5, 5, 495, 200, hwnd, (HMENU)ID_OUTBOX, hInst, NULL );

This:
   case WM_KEYDOWN:
         nVirtKey = (int) wParam;    
         if( nVirtKey == VK_RETURN && control == GetFocus() )

doesn't work.

This:
   case WM_COMMAND:
         wNotifyCode = HIWORD(wParam);
         wID = LOWORD(wParam);
         if( wID==ID_OUTBOX && wNotifyCode==EN_CHANGE )

is not what I want, I want ONLY ENTER, something like "WM_NEWLINE" or
"EN_CARRIAGERETURN".

                  Please help,
                              Robert

Normally the RETURN is "wired" into the default button on the parent form (i.e. the OK button). If you want to receive the RETURN button in your EDIT control, create it with the ES_WANTRETURN flag in the resource file or click the "Want return" in the VC++ DevStudio dialog editor.

This style has no effect on a single-line edit control.
And I'm not interesting in MFC solution, in fact I found
way out, I use NewProcEdit function as control message quelle
handler and do "case WM_KEYDOWN : if (wParam == VK_RETURN)"
OldProcEdit = (WNDPROC) SetWindowLong (chatin, GWL_WNDPROC,
                  (LONG) NewProcEdit);
ant it works great !
But thx very much :) ES_WANTRETURN is that I didn't know.
