Call DEFINE_RESPONSE_TABLEx 4 templates

How 2 call DEFINE_RESPONSE_TABLEx 4 templates ?

I want 2 build a template 4 Dialog witch can be called
as normal 'TDialog' or as 'TOleDialog' so this can be done :

*******************************************
TMyDialog::TMyDialog(TWindow * AParent)
: TDlgBase<TDialog>

==> TMyDialog acts like 'TDialog'

TMyDialog::TMyDialog(TWindow * AParent)
: TDlgBase<TOleDialog>

==> TMyDialog acts like 'TOleDialog'
*******************************************

I have done all the code but now I don´t know how to
call the DEFINE_RESPONSE_TABLEx, DECLARE_RESPONSE_TABLE Makros ?

*******************************************
Examlpe Header :

template <class TDlg> class TDlgBase
: public TDlg
{
public:

THelpDlgBase(TWindow *AParent);

protected:

void EvNCPaint();

DECLARE_RESPONSE_TABLE( TDlgBase ); /*????*/
};
********************************************

********************************************
Examlpe Cpp :

template <class TDlg>
TDlgBase<TDlg>::TDlgBase(TWindow * AParent)
: TDlg(AParent)
{
}

template <class TDlg> inline void
THelpDlgBase<TDlg>::EvNCPaint()
{
TDlg::EvNCPaint();

}

DEFINE_RESPONSE_TABLE1( THelpDlgBase , TDlg ) /*?????*/
EV_WM_NCPAINT,
END_RESPONSE_TABLE;

I don't think that answers Dirk_Sanders' question, he wants a template which takes a TWindow derived as parameter and this gives a lot of trouble with owl's DEFINE_RESPONSE_TABLE macro.
However, I think I have a (reusable) answer, requiring a few lines (8) of "code". Hint: take a look at owl/eventhan.h
.luc.

What luc said is right !

I want to use TDialog or TOleDialog as base class
but in TMyDialog there has to be the DEFINE_RESPONSE_TABLE macro !

But here is the solution :

In Header file all as usual :

************************************
DECLARE_RESPONSE_TABLE( TMyDialog );
************************************

In Cpp file a little workarround 4 the makro :

*************************************************************
template <class TDlgBase> inline bool
TMyDialog<TDlgBase>::Find(TEventInfo& eventInfo, TEqualOperator equal)
{
eventInfo.Object = (GENERIC*)this;

return SearchEntries((TGenericTableEntry __RTFAR*)__entries, eventInfo, equal) ||
TDlgBase::Find(eventInfo, equal);
}

template <class TDlgBase> inline TResponseTableEntry<TMyDialog<TDlgBase> >
__RTFAR TMyDialog<TDlgBase>::__entries[] =
{
EV_WM_NCPAINT,
EV_WM_ACTIVATE,
EV_WM_INITMENU,
EV_WM_PAINT,
EV_WM_SYSCOMMAND,
END_RESPONSE_TABLE;

***************************************************************
