關聯產品：Aspose.Words
最近做了一個在線組卷的項目。主要功能實現word排版、預覽，生成試卷。剛開始涉及到word操作一心想到的就是 office COM組件來操作word 。大概兩周時間就寫好整個系統的代碼。然后就開始反復測試，本地感覺良好，能夠順利生成一份word試卷，并且性能還行。于是迫不及待的發布到了服務器。
下面說說發布遇到的一些情況，首先一個就是遇到索 COM 類工廠中 CLSID 為 {000209FF-0000-0000-C000-000000000046} 的組件失敗，原因是出現以下錯誤: 8000401a 因為配置標識不正確，系統無法開始服務器進程。請檢查用戶名和密碼。 (異常來自 HRESULT:0x8000401A)。
首先這中問題全都是權限所導致，解決的辦法只要配置權限就可以了。不光對excel和word有用，對所有的office產品都有效果。
進入正題，首先，在運行中輸入dcomcnfg打開組件服務管理器->組件服務->我的電腦->DCOM->找到對應的Microsoft excel applicotion/Microsoft word 97-2003文檔，然后右鍵屬性激活啟動權限都給足夠了就ok了。 --------沒問題這個問題解決了。
下面再說說第二個情況》性能問題：由于我們該系統是我們網站下一個子系統。所以有一定的用戶基礎。該系統一上線就有大量的用戶訪問。剛開始一天組卷四五百份，慢慢的組卷量越來越大，這是系統就開始出問題了。首先一個就是在進程里面出現了很多 winWord.exe進程。不能結束掉。雖然系統代碼里面Quit進程，并且對資源也進行了回收，但是問題始終得不到解決。大量winword.exe進程的后果就是服務器變慢了。應為該組件辦本身就特別耗內存。
沒辦法問題要解決呀。最后的無賴之舉就是KIll 寫了一個定時服務，定時Kill掉沒有運行的winword進程。這樣做治標不治本的。、
這里要說一下微軟Office是主要針對普通用戶開發的桌面辦公應用軟件，它具有豐富的UI（用戶界面）元素，是一套純粹的本地運行軟件或者說是客戶端軟件。Word自動化接口主要是為了方便窗口應用程序調用而設計的。例如Delphi、VB、C# Winform等開發的本地應用程序。雖然可以強制Visible為false，Word可以運行在服務器端代碼里，但畢竟還是會帶來許多棘手問題。
1. ASP.NET是基于B/S架構的。B/S架構下用戶訪問都是并發的，也就是說經常會出現同時N個用戶對一個服務器頁面發出請求。在這種情況下Word自動化調用會時常出現死進程。
2. 由于隱藏界面運行，一些涉及界面的可以在窗口程序里成功調用的接口，在服務器端調用就會失敗，甚至崩潰，這種情況也會經常導致死進程。
3. 由于Word是復雜的桌面程序，并不符合一般Web服務程序簡潔高效的標準，所以在服務器端運行時速度慢，并且還會消耗大量資源(CPU、內存)，尤其不能支持大量用戶同時訪問，資源會很快耗盡。
4. 絕大部分開發者對COM技術比較陌生，在編程調用Word接口時經常存在一些代碼錯誤，而又很難檢查到問題所在，這又是導致死進程的經常因素。Word死進程不僅會消耗服務器資源，還經常會導致服務器頁面不能創建新的Word自動化對象而無法繼續工作。有網友提出死進程解決方法：編程Kill掉Word死進程，這樣是治標不治本的做法，Word死進程是不在了，可是Word非正常關閉會導致很多資源無法及時釋放。這樣的Web服務器能持續工作多久恐怕就很難說了。
為了解決這些問題，筆者經過全面研究比較，發現aspose.words完全消除了以上問題，推薦給大家分享。
