如何使用FSO搜索硬盘文件



<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>
<%
dim st
st=timer()
*************************************************************
*************搜索硬盘文件的类SearchFile *************
*************调用方法: *************
*************Set newsearch=new SearchFile 声明 *************
*************newsearch.Folder="F:+E:"传入搜索源*************
*************newsearch.keyword="汇编" 关键词*************
*************newsearch.Search 开始搜索*************
*************Set newsearch=Nothing 结束*************
*************************************************************
Class SearchFile
dim Folders 传入绝对路径,多路径使用+号连接,不能有空格
dim keyword 传入关键词
dim objFso 定义全局变量
dim Counter 定义全局变量，搜索结果的数目
*****************初始化**************************************
Private Sub Class_Initialize
Set objFso=Server.CreateObject("Scripting.FileSystemObject")
Counter=0 初始化计数器
End Sub
************************************************************
Private Sub Class_Terminate
Set objFso=Nothing
End Sub
**************公有成员,调用的方法***************************
Function Search
Folders=split(Folders,"+") 转化为数组
keyword=trim(keyword) 去掉前后空格
if keyword="" then
Response.Write("<font color=red>关键字不能为空</font><br/>")
exit Function
end if
判断是否包含非法字符
flag=instr(keyword,"") or instr(keyword,"/")
flag=flag or instr(keyword,":")
flag=flag or instr(keyword,"|")
flag=flag or instr(keyword,"&")

if flag then 关键字中不能包含/:|&
Response.Write("<font color=red>关键字不能包含/:|&</font><br/>")
Exit Function 如果包含有这个则退出
end if
多路径搜索
dim i
for i=0 to ubound(Folders)
Call GetAllFile(Folders(i)) 调用循环递归函数
next
Response.Write("共搜索到<font color=red>"&Counter&"</font>个结果")
End Function
***************历遍文件和文件夹******************************
Private Function GetAllFile(Folder)
dim objFd,objFs,objFf
Set objFd=objFso.GetFolder(Folder)
Set objFs=objFd.SubFolders
Set objFf=objFd.Files
历遍子文件夹
dim strFdName 声明子文件夹名
*********历遍子文件夹******
on error resume next
For Each OneDir In objFs
strFdName=OneDir.Name
系统文件夹不在历遍之列
If strFdName<>"Config.Msi" EQV strFdName<>"RECYCLED" EQV strFdName<>"RECYCLER" EQV strFdName<>"System Volume Information" Then
SFN=Folder&""&strFdName 绝对路径
Call GetAllFile(SFN) 调用递归
End If
Next
dim strFlName
**********历遍文件********
For Each OneFile In objFf
strFlName=OneFile.Name
desktop.ini和folder.htt不在列取范围
If strFlName<>"desktop.ini" EQV strFlName<>"folder.htt" Then
FN=Folder&""&strFlName
Counter=Counter+ColorOn(FN)
End If
Next
***************************
关闭各对象实例
Set objFd=Nothing
Set objFs=Nothing
Set objFf=Nothing
End Function
*********************生成匹配模式***********************************
Private Function CreatePattern(keyword)
CreatePattern=keyword
CreatePattern=Replace(CreatePattern,".",".")
CreatePattern=Replace(CreatePattern,"+","+")
CreatePattern=Replace(CreatePattern,"(","(")
CreatePattern=Replace(CreatePattern,")",")")
CreatePattern=Replace(CreatePattern,"[","[")
CreatePattern=Replace(CreatePattern,"]","]")
CreatePattern=Replace(CreatePattern,"{","{")
CreatePattern=Replace(CreatePattern,"}","}")
CreatePattern=Replace(CreatePattern,"*","[^\/]*") *号匹配
CreatePattern=Replace(CreatePattern,"?","[^\/]{1}") ?号匹配
CreatePattern="("&CreatePattern&")+" 整体匹配
End Function
**************************搜索并使关键字上色*************************
Private Function ColorOn(FileName)
dim objReg
Set objReg=new RegExp
objReg.Pattern=CreatePattern(keyword)
objReg.IgnoreCase=True
objReg.Global=True
retVal=objReg.Test(FileName) 进行搜索测试,如果通过则上色并输出
if retVal then
OutPut=objReg.Replace(FileName,"<font color=#FF0000>$1</font>") 设置关键字的显示颜色
***************************该部分可以根据需要修改输出************************************
OutPut="<a href=#>"&OutPut&"</a><br/>"
Response.Write(OutPut) 输出匹配的结果
*************************************可修改部分结束**************************************
ColorOn=1 加入计数器的数目
else
ColorOn=0
end if
Set objReg=Nothing
End Function
End Class
************************结束类SearchFile**********************
