Passing a const character * as a template argument

Since you must pass the string at each instanciation points, it is useless to make a template argument for it.templatestruct CVHDialogTmpl{ CVHDialogTmpl(const char *ptr_) : ptr(ptr_) { } INT_PTR DoModal() { return t.DoModal(ptr); } Ty t; ...

template<class>
struct CVHDialogTmpl
{     
	CVHDialogTmpl(const char *ptr_) : ptr(ptr_)
	{
	}     
 
	INT_PTR DoModal()
	{
		return t.DoModal(ptr);
	}
	
	Ty t;
        const char *ptr;
}; 
 
We can reuse VHRes class as defined in the original text and uses the class like this.
 
CVHDialogTmpl<cxmldlgprjdlg> dlg(VHRes::name);
 
This will works with any string including those that are built at run-time. It will be less intensive of the compiler and the generated code will probably be more efficient (memory usage).
