ADSL 撥號實現

上篇我們說到了如何實現登陸,但是騰訊對某一個IP在某一段時間的登陸行為存在檢測,對於存在異常的IP會出現驗證碼

但是騰訊的驗證碼比較難識別,或許是我對圖形識別(匹配)的技術還認識的不夠深刻

噪線,傾斜,字符連接,鏤空,噪線字符同色.這些都是識別的難點,具體的算法我試過,識別成功率很低,技術不夠沒辦法,好了偏題了,還是說ADSL撥號的實現

ADSL撥號需要調用windows api來實現

調用RASAPI32.DLL

ADSL的所有操作都要調用這個dll,詳細的調用方法和參數,大家可以查詢MSDN

不過對於我這種懶人,明白了原理,能使用拿來主義就拿哦

在codeplex上有個叫dotras的項目http://dotras.codeplex.com/這個項目封裝了rasapi dll的操作,大家可以下載下來使用,不用自己在封裝了,關於操作方法可以參見實例,下載過來后有示例的

            if (oldConn != null)
            {
