There's a bunch of special macros that MFC uses when creating dialogs, and in my quick tests I'm getting weird errors trying to compile a template dialog class. Is this likely to be a big pain to achieve?

Here's what I tried:

MyDlg.h

template <class W>
class CMyDlg : public CDialog
{
    typedef CDialog super;
    DECLARE_DYNAMIC(CMyDlg <W>)

public:
    CMyDlg (CWnd* pParent);   // standard constructor
    virtual ~CMyDlg ();

// Dialog Data
    enum { IDD = IDD_MYDLG };

protected:
    virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support

    DECLARE_MESSAGE_MAP()

private:
    W *m_pWidget; //W will always be a CDialog
};



IMPLEMENT_DYNAMIC(CMyDlg<W>, super) <-------------------

template <class W>
CMyDlg<W>::CMyDlg(CWnd* pParent)
    : super(CMyDlg::IDD, pParent)
{
  m_pWidget = new W(this);
}

I get a whole bunch of errors but main one appears to be:

error C2955: 'CMyDlg' : use of class template requires template argument list

I tried using some specialised template versions of macros but it doesn't help much, other errors change but this one remains. Note my code is all in one file, since C++ templates don't like .h/.cpp like normal.

I'm assuming someone must have done this in the past, possibly creating custom versions of macros, but I can't find it by searching, since 'template' has other meanings.
