【此刻我要大大地記錄一下!】windows
這個折騰了我好幾天的Windows 7 API終於讓我搞定了!api
利用Windows ICS API 和Windows 7 API中全新的Wireless Hosted Network,將本地的有線鏈接共享給Microsoft虛擬Wifi,使得本地計算機在windows 7下變成AP!網絡
這個操做的手動操做部分,我在前一篇文章[譯] 關於無線承載網絡(Wireless Hosted Network)中已經講明白了,可是Windows 7爲咱們提供了相關操做的API,因此,我想,能否不須要去記錄那些繁瑣的命令,也不要打開命令行,只須要用一個C++程序,將全部的操做封裝在一塊兒,那麼即可以實現!app
因而,開啓了我苦逼地閱讀Windows API的旅程。。less
其實原理很是簡單,首先想辦法開啓Windows的ICS服務,而後開啓Wireless Hosted Network,再將兩個關聯起來。但是,就是這麼easy的邏輯,老紙找這些API找了很久啊~~~主要也是以前不懂這些API怎麼用,再加上一直查不到相關的資料,最後,幾番折騰,終於在官方文檔、走過無數彎路、MSDN的友情幫助,以及各大論壇的細枝末節中,我終於找到蛛絲馬跡,將功能徹底實現了!函數
廢話很少說,直接上代碼!ui

我簡單解釋一下代碼:(1)第一個函數是HRESULT AddSharingNet (INetSharingManager* pNSM),這個函數的做用就是開啓ICS服務,而且將ICS服務共享出去。除此以外,我在函數中將全部的網絡適配器都打印了出來,能夠爲進一步開發作鋪墊。這裏面比較重要的一個地方是用紅色標記出來的,也就是說,ICS須要PUBLIC的共享。另外一個重要的地方是用藍色標記出來的,這裏主要說明的是,在找到Microsoft 虛擬Wifi以後,你須要爲這個虛擬wifi作映射,那麼映射以前你得先找到這個網絡適配器,因此就先將它保存在pVWifiNSC中,而後這個時候記錄下來的適配器是虛擬Wifi,這是將虛擬wifi進行PRIVATE共享,它會自動和本機的有線鏈接進行關聯,實現內部的ICS共享。這一步就是這麼簡單,可是就是這麼簡單,然我嘗試了N種方法,最終終於搞定!
(2)第二個函數是HRESULT StartHostednetwork(),這個函數很簡單,就是開啓Wireless Hosted Network,若是你對這裏不熟悉,很容易在Windows 7 API W部分找到這些API,並且個人上一篇文章頁提到了如何使用這些API。
就這樣,整個工做就結束了,老紙但是花了九牛二虎之力才搞定的,真的不容易啊!
期間走了不少彎路,並且發現沒有其餘人寫過相似的代碼,連個能夠參考的都沒有,最後本身摸黑走,實驗了不少種API,思來想去找了不少種辦法,都不成功,最後幾經周折,功夫不負有心人,終於將問題搞定!
不得不感嘆一下啊!哈哈~
