这里的不成功有几种，我是第2种，我分别说明一下：

第1种：出现文件根本无法上传的情况，这是由于无惧上传类v2.2的一个BUG

使用了“无惧上传类 v2.2”，在运行中出现这样一个问题，上传文件时提示上传成功，但文件实际上并没有传上去。然而，如果使用“无惧上传类 v1.2”的话就没有这个问题。经过对比代码，找到了问题的所在，我认为这应该是“无惧上传类 v2.2”的一个BUG。
在UpFile_Class类的SaveToFileEx成员函数中有这样两行：

tmpPath=Split(Path,".")(0)
FileExt=GetFileExt(Path)

后面判断若没有问题可以上传，则执行这样一行将文件写到本机中：

oFileStream.SaveToFile tmpPath & "." & FileExt,2

Path是上传的文件在本机的全路径。可以看出，作者的本意是tmpPath的值为文件本机全路径去掉扩展名和连接扩展名的“.”，这样做主要是基于安全上的考虑。然而，实际使用时路径中有一个“.”，如“D:/web/aaa.com/bbb/”，这样，tmpPath的值就是“D:/web/aaa”，这明显是错误的。出现了这样的问题依然提示上传成功的原因是SaveToFileEx函数的开头有一个“On Error Resume Next”。

这样，我们对SaveToFileEx函数进行一些修改，让其先截取路径和文件名，存放于onlyPath和onlyFileName中，再对onlyFileName进行扩展名截取。将tmpPath=Split(Path,".")(0)修改为以下代码：

for i=len(Path) to 1 step -1
if mid(Path, i, 1) = "/" or mid(Path, i, 1) = "/" then exit for
next
onlyPath = left(Path, i)
onlyFileName = right(Path, len(Path) - i)
tmpFileName = Split(onlyFileName,".")(0)

然后将写文件的代码改成这样：

oFileStream.SaveToFile OnlyPath & tmpFileName & "." & FileExt,2

进行了这样的修改，再运行就没有问题了。这个是文件保存路径不对造成的。

第2种：文件上传成功到指定的目录，但无法加载到ubb编辑框里，或者加载到ubb编辑里是个不一样的文件名。

若把upload.asp文件开头的on error resume next去掉，上传文件的过程会出如下错误：
/upload.asp，行300说是无权限 但是明明文件可以上传啊？300行代码是：

Function moveFile(oldfile,newfile)
dim fs
Set fs=Server.CreateObject("Scri"&"pting.File"&"Sys"&"temObject")
fs.movefile Server.MapPath(oldfile),Server.MapPath(newfile) （第300行）
Set fs=Nothing
End Function

本地测试文件上传成功，服务器也上传到了指定目录，就是无法这个moveFile函数，这是为什么呢？

有个原因：会不会是服务器上目录结构存在差异，如果跟踪一下Server.MapPath(newfile) ，看这个是否正确？

我测试过，找不出问题，只好不要这个函数，而是直接把上传后的文件名oldfile直接赋给newfile
