<link rel="stylesheet" href="style.css">
<% if Request.QueryString("action")="do" then
currf=request.form("currf")
currf = server.mappath(currf)
ys=request.form("ys")
Const JET_3X = 4
strDBPath = left(currf,instrrev(currf,"\"))
on error resume next
Set objfso = Server.CreateObject("Scripting.FileSystemObject")
if err then
err.clear
response.write "<div class=tdc>不能建立fso对象，请确保你的空间支持fso:！"
response.end
end if
if objfso.fileexists(currf) then
Set Engine = CreateObject("JRO.JetEngine")
on error resume next
If ys = 1 Then
Engine.CompactDatabase "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & currf, _
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDBPath & "fytemp.mdb;" _

End If
objfso.CopyFile strDBPath & "fytemp.mdb",currf
objfso.DeleteFile(strDBPath & "fytemp.mdb")
Set objfso = nothing
Set Engine = nothing
if err then
err.clear
response.write "<div class=tdc color=#ff0000>错误：很抱歉，由于系统错误，压缩失败:！"
response.end
end if
response.write "<div class=tdc>压缩数据库成功</div>"
response.end
Else
response.write "<div class=tdc>错误:找不到数据库文件！"
response.end
End If
end if
