Webclass实例：http://www.shinco.com/jjx/wcnews/news.asp
许多文件上传组件并不能在vb中正常使用，我测试了chinaasp fileup,aspSmartupload,aspupload
enterprise,inotesupload等组件，均不能正
常使用。其主要原因，是因为在vb中没有促发组件的OnStartPage过程。我们无法改写这些组件，所以要自己编码来解决这
个问题，记得以前有网友谈过这个问题，但没有代码贴出来。
其实以前chinaasp上有个编写web方式上载文件的组件的贴子(我一下找不了，这是我转贴的地址
http://www.shinco.com/jjx/activeubb/NewsDetail.asp?id=134,稍微改写一下就能在webclass中使用了

将原onstartpage过程改为
Public Sub OnStartPage(PassedRequest As Request)

------------------定义局部变量----------------------
Dim varByteCount
Dim i
---------------------------------------------------

------------------建立ASP对象-----------------------
Set MyRequest = PassedRequest
---------------------------------------------------

------------------读取客户端传来的全部数据-----------
varByteCount = MyRequest.TotalBytes
lngArrayLen = varByteCount - 1
ReDim binArray(varByteCount - 1)
binArray = MyRequest.BinaryRead(varByteCount)
---------------------------------------------------

--------------------获取定界符---------------------
intDjfLen = 0
Do Until binArray(intDjfLen + 1) = 13
intDjfLen = intDjfLen + 1
Loop
ReDim binDjf(intDjfLen)
For i = 0 To intDjfLen
binDjf(i) = binArray(i)
Next
---------------------------------------------------
End Sub

在webclass中使用

dim upload as new uploadfile
upload.onstartpage(request)

然后就可以用该类提供的方法了进行操作了，这个组件的功能比chinaasp upload要差些。但已经足够使用了

其他改动

1、为了能用getthevalue方法正确取得input type 为checkbox,radio等的值，在

FindtheName中加入错误处理
Private Function FindTheName(nm As String) As Long
On Error GoTo FindTheNameError
******************************参数说明*****************************
* *
* nm: 要寻找的 Form 元素名 *
* 返回值： 成功—— 找到时的地址，失败—— -1 *
* *
*******************************************************************

------------------定义局部变量----------------------
Dim s As Long
Dim e As Long
Dim i As Long

Dim binTmp() As Byte
Dim strName As String
---------------------------------------------------

------------------寻找要取得值的Form 元素名------------------------
s = 0
Do While 1
s = FindTheDjf(s)
If s <> -1 Then
s = s + intDjfLen + 41
e = s
Do While binArray(e + 1) <> 34
e = e + 1
Loop
ReDim binTmp(e - s)
For i = s To e
binTmp(i - s) = binArray(i)
Next
strName = StrConv(binTmp, 64)
If StrComp(nm, strName) = 0 Then
FindTheName = e + 1
Exit Do
End If
Else
FindTheName = -1
Exit Do
End If
Loop
--------------------------------------------------------------
Exit Function
FindTheNameError:
FindTheName = -1

End Function

2、删除类声明中的
Private MyScriptingContext As ScriptingContext定义
