FSO組件之檔操作
作者:tank 日期:2005-01-09
FSO,正如UFO般令人激動、令人神往,當然更多的亦是讓人歡喜讓人憂。君不見某空間服務商廣告:100MB空間只要60RMB/年,支持數據庫,支持什么什么……一問不支持FSO,立馬泄氣。那FSO究竟是什么東西,它的力量又是如何巨大,其操作的原理又是怎的怎的呢?這次來個徹底的理解。
首先,FSO是FileSystemObject的簡稱。當然也就是我們的俗稱FSO組件了,該組件可以用來處理驅動器、文件夾以及文件。
它可以檢測并顯示出系統驅動器的信息分配情況;還能夠創建、改變、移動和刪除文件夾,并能探測一些給定的文件夾是否存在,若存在,還能提取出該文件夾的信息,如名稱、被創建或最后一次修改的日期,等等。FSO還使得對文件的處理變得很容易。
一、fso.GetDrive

利用ASP實現事務處理的方法
作者:tank 日期:2005-01-09
在開發Web應用時,無一例外地需要訪問數據庫,以完成對數據的查詢、插入、更新、刪除等操作。受應用邏輯的影響,有時需要將多條數據庫操作指令組成一個工作單元(事務)。在數據庫中,所謂事務是指一組邏輯操作單元,它使數據從一種狀態變換到另一種狀態。為確保數據庫中數據的一致性,應當用離散的成組的邏輯單元操作數據:當它全部完成時,數據的一致性可以保持;而當單元中的一部分操作失敗時,整個事務會被全部忽略,所有從起始點以後的操作全部退回到開始狀態。
實際上,在默認方式下對數據庫的每一次操作都是隱含的事務處理。本文以一個典型的用戶注冊程序為例,介紹三種利用ASP實現事務處理的方法:基于ASP數據庫組件的解決方法、基于數據庫內部的事務處理機制的解決方法和基于MTS組件的解決方法。
