??? 一直在用Lingoes作為翻譯工具，占用空間小，運行比較穩定，詞典可以任意切換，使用起來要比Kingsoft的詞霸感覺－－“輕松”～
??? Lingoes有個沒法和詞霸相比的功能－－生詞本。對于我這樣記性不好的人來說，如果能夠記錄自己曾經“認真”背誦過的單詞，然后再“強化”一下，應該會有好的效果（實際差不多，一樣過三天就記不住了），因此這個功能對我來說比較－－實用。但，Lingoes無此功能～
??? 在網上查找，發現很有些人跟我有同感，并也有人士完成了此功能，大喜，下載使用，嗯，功能都有，只是我用起來不太順手。于是，發揚“輪子精神”，然后便有了這個－－LingosHook～
??? 如其名字，由于無法知道Lngoes內部實現，只能走旁門－－HOOK了。而如我們所知，要想用Hook，DLL是少不了的，前期關于DLL的練習也做了很久了，但上周才把可用的DLL剛剛調試完成，然后加上一個測試的App，就有了下面的截圖。
??? 上圖中，顯式了由Lingoes結果窗口（未截圖）中Hook到的HTML和TEXT內容，這樣在加上SQLite和一些管理策略代碼，一個生詞本應該就可以完成了.
??? 實現的關鍵還是Hook的DLL，有興趣，請點擊這里下載。其中包括了測試用的App。DLL的exports如下：
??? CreateHookThread用于“注冊”，RemoveHookThread用于“卸載”。下面是調用的主要代碼，我使用的開發測試環境是XP SP3+VCExpress 9.0＋wxWidgets 2.8.10，還有lingoes 2.63。如果測試的app不能運行，請先到MS下載相應的VC發布包試試。
??
? ? 實現步驟如下：
??? 1.向Lingoes注冊截取消息的Hook DLL;
??? 2.創建線程，用于等待Hook發現Lingoes“截取到文本”觸發的WM_COPYDATA消息后的事件；
??? 3.線程收到事件后，向注冊進程發送內部消息，轉發Lingoes的翻譯結果，其中結果分為HTML和TEXT兩種結果；
??? 4.注冊線程收到消息后，顯式結果。
??? 注冊代碼：
