Many many thanks to DeadMG stack overflow http://stackoverflow.com/questions/3773378/passing-const-char-as-template-argument[^]

template<class _Ty, const wchar_t* ptr> 
struct CVHDialogTmpl
{     
	CVHDialogTmpl()
	{
	}     

	INT_PTR DoModal()
	{
		return t.DoModal(ptr);
	}
	
	_Ty t;
}; 

class VHRes
{
public:
    static const wchar_t name[];
};

const wchar_t VHRes::name[] = L"XMLDlgPrj.xml";

CVHDialogTmpl<CXMLDlgPrjDlg, VHRes::name> dlg;
