? ? ?這篇文章我一直想寫，但是一直沒有動筆，因為這里面牽扯的內容太多，而且有一部分并非我原創，拿出來有班門弄斧之嫌，所以一拖再拖，現在感覺可以把自己的一些經驗心得和大家分享一下了。

? ? ? ?現在webui的使用范圍很廣，在一些大型軟件上隨處可見，其實這東西說白了也不難，就是c++（當然，也可以是其他語言）加個webbrowser，然后客戶端與網頁進行通信，牽扯到的主要是com技術。

? ? ? ?主要部分的代碼就上面這些，cwebdialog這個類就是webbrowser，需要由mfc窗口繼承，在gethwnd虛函數里返回mfc窗口的句柄，cexternal這個類就是重寫webbrowser的external對象，讓其指向宏ONFUNCEVEVT所創建的函數。CWebControl是webui控件的基類，webui所創建的控件都是從這個類上繼承的。我們在c++客戶端只需要調用initwebui即可完成webui的初始化操作，如果你當前有一個網頁需要與客戶端交互，LoadUIFromHtml這個方法是你的選擇，下面給出一個實例：

? ? ? 以上代碼是我最近編寫的一個微筆記程序里的代碼，有時間我把完整的程序發上來。

? ? 不得不說的是這個webui有一個bug，就是無法響應html里的onkeydown事件，自己摸索半天仍然不知所謂何因，有大俠知道還望賜教。

? ? 本文有不足之處，還望大家多多指正。
