如何对文件进行操作？
这可是个综合性的问题，看看下面对文件操作的集大成代码：
<%@ LANGUAGE="VBScript" %> <% 'Set file i/o constants. Const ForReading = 1 Const ForWriting = 2 Const ForAppending = 8 filename = "test.txt" path = Server.MapPath("data") & "\" & filename
' 映射文件名到服务器的物理路径 operation = Request.Form("operation") %>
' 得到请求操作 <html> <head> <title>精彩春风之处理文件</title> </head> <body> <font face="Arial,Helvetica" size=2> <table bgcolor="#000000" border=0 cellpadding=1 cellspacing=0><tr><td> <table bgcolor="#008080" border=0 cellpadding=8 cellspacing=0><tr valign=bottom><td> <font face="Arial,Helvetica" size=2> <form action="<% = Request.ServerVariables("SCRIPT_NAME") %>" method="post"> <input name="operation" type="radio" value="create"> 创建 <input name="operation" type="radio" value="delete"> 删除 <input name="operation" type="radio" value="read" checked> 读取 <input name="operation" type="radio" value="write"> 写入 <input name="operation" type="radio" value="append"> 添加 <p> <center> <input type="submit" value="确定"> <input type="reset" value="重置"> </center> </form> <p> <a href="fileops.html"><b>返回</b></a> </font> </td></tr></table> </td></tr></table> <p> <% if operation = "create" then call CreateFile(path) call ReadFile(path) elseif operation = "delete" then call DeleteFile(path) elseif operation = "read" then call ReadFile(path) elseif operation = "write" then call WriteFile(path) call ReadFile(path) elseif operation = "append" then call AppendFile(path) call ReadFile(path) end if
' 执行请求操作 %> <p> </font> </body> </html> <% sub CreateFile(path) dim fs, file set fs = CreateObject("Scripting.FileSystemObject") if fs.FileExists(path) then Response.Write(<b>噢,文件" & filename & " 已经存在,创建失败!</b><br>" & vbCrLf)
' 如果文件早已存在则显示一个错误信息 else Response.Write(恭喜, " & filename & "创建成功!<br>" & vbCrLf)

' 当需要给它添加新内容时打开或创建文件 file.Close() end sub %>
