   if(pMsg->message == WM_KEYDOWN)
      {
            if(pMsg->wParam == VK_RIGHT)
            {
                  NextDlgCtrl();
                  return true;  //prevent default behaviour
            }
            else if(pMsg->wParam == VK_LEFT)

from help

CDialog::NextDlgCtrl
void NextDlgCtrl( ) const;

Remarks

Moves the focus to the next control in the dialog box. If the focus is at the last control in the dialog box, it moves to the first control.

If it isn't CDialog based then

CWnd::GetNextDlgTabItem  
CWnd* GetNextDlgTabItem( CWnd* pWndCtl, BOOL bPrevious = FALSE ) const;

Return Value

Pointer to the previous (or next) control that has the WS_TABSTOP style, if the member function is successful.

The returned pointer may be temporary and should not be stored for later use.

Parameters

pWndCtl

Identifies the control to be used as the starting point for the search.

bPrevious

Specifies how the function is to search the dialog box. If TRUE, the function searches for the previous control in the dialog box; if FALSE, it searches for the next control.

Remarks

Retrieves a pointer to the first control that was created with the WS_TABSTOP style and that precedes (or follows) the specified control.



ie to move to next
GetNextDlgItem(GetFocus(), false)->SetFocus();//swap false for true to move to prev

Try this, it modifies the right arrow to tab and left arrow to shift tab, then passes to the actual pretranslate for default processing.

BOOL CFormTestView::PreTranslateMessage(MSG* pMsg)
{
      if(pMsg->message == WM_KEYDOWN)
      {
            if(pMsg->wParam == VK_RIGHT)
                  pMsg->wParam = VK_TAB ;
            else if(pMsg->wParam == VK_LEFT)
            {
                  pMsg->wParam = VK_TAB ;
                  //Set the shift key state
                  static BYTE bytKeyBuff[256] ;
                  GetKeyboardState((PBYTE)&bytKeyBuff) ;

                  //toggle shift key.
                  bytKeyBuff[VK_SHIFT] |= 0x80 ;//set the high bit to 1
                  SetKeyboardState((PBYTE)&bytKeyBuff) ;
                  //let the pretranslate do it's default thing
                  BOOL bReturn = CFormView::PreTranslateMessage(pMsg) ;
                  //toggle back to the original state
                  bytKeyBuff[VK_SHIFT] &= 0x7F ;//set the high bit to 0
                  SetKeyboardState((PBYTE)&bytKeyBuff) ;
                  return bReturn ;
            }
      }
      return CFormView::PreTranslateMessage(pMsg) ;
}
