可以看到库文件的生成目录，保存下来

我们创建一个按钮调用我们刚才的函数

这边这么调用MFC库的函数入口。这里并不是com控件，所以不能直接从引用里面拉进来。
否则会报 未能添加引用，请确保此文件可访问并且是一个有效的程序集或COM组件。 错误 ![2016-04-04_221955[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE1LmNuYmxvZ3MuY29tL2Jsb2cvNDczMTgzLzIwMTYwNC80NzMxODMtMjAxNjA0MDUxMDQyNDE2NTYtNTc4Mzk5Nzk0LmpwZw==.png "2016-04-04_221955[4]")
添加using

调用方式就像类的静态方法

这里看到设置的入口函数和声明的不一样。
![2016-04-04_222205[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE1LmNuYmxvZ3MuY29tL2Jsb2cvNDczMTgzLzIwMTYwNC80NzMxODMtMjAxNjA0MDUxMDQyNDU1NzgtNDE4MDA0NDIxLmpwZw==.png "2016-04-04_222205[4]")
所以会报错
![2016-04-04_222320[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE1LmNuYmxvZ3MuY29tL2Jsb2cvNDczMTgzLzIwMTYwNC80NzMxODMtMjAxNjA0MDUxMDQyNDcxMDktNTkzNzM2ODY0LmpwZw==.png "2016-04-04_222320[4]")
我们把入口 entryPoint修改一下。或者删掉。只要保持和库那边设置一致即可
![2016-04-04_222349[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE1LmNuYmxvZ3MuY29tL2Jsb2cvNDczMTgzLzIwMTYwNC80NzMxODMtMjAxNjA0MDUxMDQyNDg2ODctMjEyMjA0MzkzNC5qcGc=.png "2016-04-04_222349[4]")
效果如下

现在我们添加MFC的窗口

在声明出使用doModel的原因是退出函数这里会释放资源。如果show会出错

在跨语言调用中，有可能会出现消息队列不一致问题。这里测试一下。在不乱设置的情况下。窗口消息响应
