Need to capture enter key message, in OnBnClickedOk() function, then add below code:

CWnd* pwndCtrl = GetFocus();
     CWnd* pwndCtrlNext = pwndCtrl;
     int ctrl_ID = pwndCtrl->GetDlgCtrlID();


     switch (ctrl_ID) {
         case IDC_Name:
             pwndCtrlNext = GetDlgItem(IDC_PASSWORD);
pwndCtrlNext->SetFocus();
             return;
//break;  
         default:
             break;
     }
