一个模板生成HTML的类，在用VB编为DLL的时候遇到问题

ASP初始代码

'【功能】处理自定义模板标签
Function ProcessCustomTags(ByVal sContent)
Dim objRegEx, Match, Matches
'建立正则表达式
Set objRegEx = New RegExp
'查找内容
objRegEx.Pattern = "<fmtag:[^<>]+?\/>"
'忽略大小写
objRegEx.IgnoreCase = True
'全局查找
objRegEx.Global = True
'Run the search against the content string we've been passed
Set Matches = objRegEx.Execute(sContent)
'循环已发现的匹配
For Each Match in Matches
'Replace each match with the appropriate HTML from our ParseTag function
sContent = Replace(sContent, Match.Value, ParseTag(Match.Value))
Next
'消毁对象
set Matches = nothing
set objRegEx = nothing
'返回值
ProcessCustomTags = sContent
End Function

'【功能】取得模板标签的参数名
'如：<tag:loop channelid="1" pagesize="10" title="20" type="NEW" column="1">
function GetAttribute(ByVal strAttribute, ByVal strTag)
Dim objRegEx, Matches
'建立正则表达式
Set objRegEx = New RegExp
'查找内容 (the attribute name followed by double quotes etc)
objRegEx.Pattern = lCase(strAttribute) & "=""[0-9a-zA-Z]*"""
'忽略大小写
objRegEx.IgnoreCase = True
'全局查找
objRegEx.Global = True
'执行搜索
Set Matches = objRegEx.Execute(strTag)
'如有匹配的则返回值, 不然返回空值
if Matches.Count > 0 then
GetAttribute = Split(Matches(0).Value,"""")(1)
else
GetAttribute = ""
end if
'消毁对象
set Matches = nothing
set objRegEx = nothing
end function

'【功能】解析并替换相应的模板标签内容
function ParseTag(ByVal strTag)
dim arrResult, ClassName, arrAttributes, sTemp, i, objClass
'如果标签是空的则退出函数
if len(strTag) = 0 then exit function
'Split the match on the colon character (:)
arrResult = Split(strTag, ":")
'Split the second item of the resulting array on the space character, to
'retrieve the name of the class
ClassName = Split(arrResult(1), " ")(0)
'Use a select case statement to work out which class we're dealing with
'and therefore which properties to populate etc
select case uCase(ClassName)
'It's a loop class, so instantiate one and get it's properties
case "LOOP"
set objClass = new WawaLoop
objClass.Channelid= GetAttribute("channelid", strTag)
objClass.Pagesize= GetAttribute("pagesize", strTag)
objClass.title = GetAttribute("title", strTag)
objClass.Elite = GetAttribute("elite", strTag)
ParseTag =objClass.column (GetAttribute("column", strTag))
set objClass = nothing
end select
end function
'【功能】实际替换标签的类
Class WawaLoop
public Channelid,Pagesize,title,Elite,conn
Private Sub Class_Initialize()
'dim connstr
'dim db
'db="wawa.mdb"
'Set conn = Server.CreateObject("ADODB.Connection")

'conn.Open connstr
'ConnectionDatabase

ConnStr = "Provider = Sqloledb; User ID = " & SqlUsername & "; Password = " & SqlPassword & "; Initial Catalog = " & SqlDatabaseName & "; Data Source = " & SqlLocalName & ";"
Set Conn = server.CreateObject("ADODB.Connection")
conn.open ConnStr

End Sub
Public Function column(strColumn)

dim i,rs,sql,strtemp
i = 1
strtemp = strtemp& "<table width=100% border=0>"
strtemp = strtemp&"<tr>"
set rs=server.CreateObject("adodb.recordset")
'sql = "select top "&Pagesize&" * from fmoa_res_system where id="&Channelid&" and Elite="&Elite&""
sql = "select top "&Pagesize&" * from fmoa_res_system where sortid="&Channelid&" "
Response.Write sql

rs.open sql,conn,1,1
do while not rs.eof
strtemp = strtemp& "<td valign=top>" &lefttrue(rs("title"),title) & "</td>"
if (i mod strColumn) =0 then
strtemp = strtemp& "</tr><tr>"
end if
rs.movenext
i=i+1
loop
rs.close:set rs = nothing
strtemp = strtemp& "</table>"
column = strtemp
End Function
End Class
'【功能】截断字符串的一个函数
Function LeftTrue(str,n)
If len(str)<=n/2 Then
LeftTrue=str
Else
Dim TStr
Dim l,t,c
Dim i
l=len(str)
TStr=""
t=0
for i=1 to l
c=asc(mid(str,i,1))
If c<0 then c=c+65536
If c>255 then
t=t+2
Else
t=t+1
End If
If t>n Then exit for
TStr=TStr&(mid(str,i,1))
next
LeftTrue = TStr & "..."
End If
End Function
Function ReadAllTextFile
Const ForReading = 1
Dim fso, f
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(Server.MapPath("template1.htm"), ForReading)
ReadAllTextFile = f.ReadAll
End Function
'最后输出模板转换后的代码
response.write ProcessCustomTags(ReadAllTextFile)
%>

在VB下面复制过去后，出现问题：

set objClass = new WawaLoop

Class WawaLoop

提示出错！

请问大家有没有相关类转为DLL的例子我参考，或者相关的参考资料，非常感谢大家！
