我們創建一個按鈕調用我們剛才的函數

這邊這么調用MFC庫的函數入口。這里並不是com控件，所以不能直接從引用里面拉進來。
否則會報 未能添加引用，請確保此文件可訪問並且是一個有效的程序集或COM組件。 錯誤 ![2016-04-04_221955[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE1LmNuYmxvZ3MuY29tL2Jsb2cvNDczMTgzLzIwMTYwNC80NzMxODMtMjAxNjA0MDUxMDQyNDE2NTYtNTc4Mzk5Nzk0LmpwZw==.png "2016-04-04_221955[4]")
添加using

調用方式就像類的靜態方法

這里看到設置的入口函數和聲明的不一樣。
![2016-04-04_222205[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE1LmNuYmxvZ3MuY29tL2Jsb2cvNDczMTgzLzIwMTYwNC80NzMxODMtMjAxNjA0MDUxMDQyNDU1NzgtNDE4MDA0NDIxLmpwZw==.png "2016-04-04_222205[4]")
所以會報錯

我們把入口 entryPoint修改一下。或者刪掉。只要保持和庫那邊設置一致即可

在聲明出使用doModel的原因是退出函數這里會釋放資源。如果show會出錯

在跨語言調用中，有可能會出現消息隊列不一致問題。這里測試一下。在不亂設置的情況下。窗口消息響應
