我做了个MFC的dlg, 现在想使用这个代码的功能, 如果直接派生, 会有一大堆错误, 而且是我无法解决的, 最终显示_model 没有定义...我已经把这段代码改成MFC的了, 但是问题来了, 他使用了模板, 也就是说, 其他Cwnd类型的窗口(对话框) 只需要派生他, 就可以实现他的功能.T* pT = static_cast<T*>(this); 这一句太奇妙了, 可是我MFC怎么用呢?

传统面向对象的MFC架构下怎么做?当然是virtual函数.但virtual函数带来速度和空间开销.这也是为什么wtl和mfc比
时会被称为轻量级..等等的原因. WTL和MFC在对c++的运用上几乎不是一路的。WTL基本的特性是基于ATL，而设计ATL就是为了将接口和实现分开,你上面所提的内容都是接口部分,而且T* pT = static_cast<T*>(this); 这种典型的多种继承,对子类进行绑定的做法,要转到MFC不好搞,你还是试试Virtual函数吧,或者将对像的构建和销毁移出来就可以不用这一句了.
那是因为我放弃了那个WTL, 然后只有他一个人回答,我就把分给他了
