我想创建与ASP经典的网页，用户可以上传文件或文件夹压缩。
我已经在谷歌搜索，但每次我都找到解决方案使用第三方文件。 但我还没有能够得到这些文件的工作。
Answer 1:
很长时间以来，我已经做了，但我们不使用第三方组件的上载，短短两年的VBScript类（溶液归功于刘易斯MOTEN）。
它看起来像你仍然可以找到野生这种“刘易斯MOTEN解决方案”
如果包括clsUpload文件，进一步上传过程就是这么简单：
Dim objUpload
Dim strFile, strPath
' Instantiate Upload Class '
Set objUpload = New clsUpload
strFile = objUpload.Fields("file").FileName
strPath = server.mappath("/data") & "/" & strFile
' Save the binary data to the file system '
objUpload("file").SaveAs strPath
Set objUpload = Nothing
这是所有服务器端...
在客户端，你只需要你的文件输入
<form name="Upload" enctype="multipart/form-data" method="post" action="clsUpload.asp">
<div>Upload file: </div>
<div><INPUT TYPE="file" NAME="file" >
<input type="button" name="FileUpload" value="Upload File"> </div>
</form>
希望这可以帮助..

作为武汉理工大学我提到的“野生”的解决方案所指出的Dave是与提供的代码片段完全一致。 在此，我历来使用完整的类（评论修剪留30000 SO极限以下）。 据刘易斯MOTEN解决方案的早期版本中发现的http://planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=8525&lngWId=4

lobjField.Name = pstrName
lobjField.FilePath = pstrFileName
lobjField.FileName = Mid(pstrFileName, InStrRev(pstrFileName, "\") + 1) ' <= line added to set the file name
lobjField.ContentType = pstrContentType
你还必须声明下面的常数：常数adSaveCreateOverWrite = 2
Answer 3:
不幸的是，它不会没有至少上使用第三方脚本和做一些调整，以你的服务器了多大的努力才有可能建立一个上传服务。
您可以使用自己的托管服务提供商已安装的组件列表但检查; 大多数托管服务也保持库/常见问题/维基与如何使用这些组件几乎现成的例子。 如果没有，还有FreeAspUpload这是一个免费DLL的组件，因此可以在任何传统的ASP服务器上使用。
确定将使用哪种成分/脚本后，你还必须检查目标上传文件夹的写权限。 如果你不能设定许可写入文件的目标文件夹，你的上传将无法正常工作。 请检查您的托管服务提供商的控制面板让您能够做到这一点，或者如果你需要为这些变化的请求。
