用VBS可执行程序＋Xmlhttp下载网络文件

'On Error Resume Next
Dim iRemote,iLocal
iRemote = InputBox("请输入远程文件路径：")
Set xPost = CreateObject("Microsoft.XMLHTTP")
xPost.Open "GET",iRemote,0
xPost.Send()
Set stream = CreateObject("ADODB.Stream")
stream.Mode = 3
stream.Type = 1
stream.Open()
stream.Write(xPost.responseBody)
if (stream.size<10240) then
MsgBox("远程文件不存在！")
else
SaveFile
end if
stream.close
set stream = nothing

' 保存文件
function SaveFile
iLocal = InputBox("请输入本机保存路径：")
Set fso = CreateObject("Scripting.FileSystemObject")
returnValue = "0"
if (fso.FileExists(iLocal)) then
returnValue = MsgBox("'"&iLocal&"'文件已存在，真的要覆盖吗？",vbYesNoCancel,"确认框")
end if
set fso = nothing
if (returnValue = "6" or returnValue = "0") then '覆盖
stream.SaveToFile iLocal,2
MsgBox("文件备份成功！")
elseif (returnValue = "7") then
SaveFile
end if
end function
保存为VBS后缀的文件，直接双击运行就可以了。
