三、程序清单
Global.bas中的代码：
Public objContext As ObjectContext
Public Application As ASPTypeLibrary.Application
Public Server As ASPTypeLibrary.Server
Public Session As ASPTypeLibrary.Session
Public Response As ASPTypeLibrary.Response
Public Request As ASPTypeLibrary.Request
Class1.cls中的代码：
Private Sub Class_Initialize()
On Error Resume Next
Set objContext = GetObjectContext
Set Application = objContext.Item("Application")
Set Server = objContext.Item("Server")
Set Session = objContext.Item("Session")
Set Request = objContext.Item("Request")
Set Response = objContext.Item("Response")
End Sub
Private Sub Class_Terminate()
On Error Resume Next
Set Application = Nothing
Set Server = Nothing
Set Session = Nothing
Set Request = Nothing
Set Response = Nothing
Set objContext = Nothing
End Sub
Public Sub AspClassInit()
On Error GoTo Err
Set conn = Server.CreateObject("ADODB.Connection")
strcon = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & Server.MapPath("Article.mdb")
conn.Open strcon
Set rs = Server.CreateObject("ADODB.Recordset")
sql = "select * from Article order by ArticleID desc"
rs.Open sql, conn, 1, 1
Response.Write "<html>" & vbCrLf
Response.Write "<head>" & vbCrLf
Response.Write "<meta http-equiv=""Content-Type"" content=""text/html; charset=gb2312"">" & vbCrLf
Response.Write "<title>文章管理系统-CSSTUDIO</title>" & vbCrLf
Response.Write "</head>" & vbCrLf
Response.Write "<body bgcolor=""#FFFFFF"" topmargin=""0"">" & vbCrLf
Response.Write "<table width=""100%"" border=""0"" cellpadding=""2"" cellspacing=""0"">" & vbCrLf
Response.Write " <tr>" & vbCrLf
Response.Write " <td width=""742"" height=""20"">文章标题</td>" & vbCrLf
Response.Write " <td width=""90"">点击</td>" & vbCrLf
Response.Write " <td width=""145"">添加日期</td>" & vbCrLf
Response.Write " </tr>" & vbCrLf
Response.Write "</table>" & vbCrLf
While Not rs.EOF And Rows < rs.PageSize
Response.Write "<table width=""100%"" border=""0"" cellspacing=""0"" cellpadding=""0"">" & vbCrLf
Response.Write " <tr>" & vbCrLf
Response.Write " <td width=""747"" height=""20"">☆<a href=""view.asp?id="
Response.Write rs("ArticleID")
Response.Write """>" & vbCrLf
Response.Write " "
Response.Write rs("标题")
Response.Write "</a></td>" & vbCrLf
Response.Write " <td width=""94"">"
Response.Write rs("点击")
Response.Write "</td>" & vbCrLf
Response.Write " <td width=""148"">"
Response.Write rs("添加日期")
Response.Write "</td>" & vbCrLf
Response.Write " </tr>" & vbCrLf
Response.Write "</table>" & vbCrLf
rs.MoveNext
Wend
Response.Write "</body>" & vbCrLf
Response.Write "</html>" & vbCrLf
rs.Close
Set rs = Nothing
conn.Close
Set conn = Nothing
Exit Sub
Err:
If Err.Number = -13572468 Then Exit Sub
Resume Next
End Sub
使用article.dll后的index.asp中的代码：
<%Dim AspTransBuilderObject
Set AspTransBuilderObject = Server.CreateObject("article.Class1")
AspTransBuilderObject.AspClassInit
Set AspTransBuilderObject = Nothing%>
使用article.dll前的index.asp中的代码：
<% Set conn=Server.CreateObject("ADODB.Connection")
strcon = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & Server.MapPath("Article.mdb")
conn.Open strcon %>
<% Set rs = Server.CreateObject ("ADODB.Recordset")
sql="select * from Article order by ArticleID desc"
rs.Open sql, Conn,1,1 %>
<html>
<head>
<meta http-equiv ="Content-Type" content="text/html; charset=gb2312">
<title>文章管理系统-CSSTUDIO</title>
</head>
<body bgcolor="#FFFFFF" topmargin="0">
<table width="100%" border="0" cellpadding="2"
cellspacing="0">
<tr>
<td width="742" height="20">文章标题</td>
<td width="90">点击</td>
<td width="145">添加日期</td>
</tr>
</table>
<% While Not Rs.Eof And Rows<Rs.PageSize %>
<table width="100%" border="0" cellspacing="0"
cellpadding="0">
<tr>
<td width="747" height="20">☆<a href="view.asp?id=<%
= rs("ArticleID") %>">
<% =rs("标题") %></a></td>
<td width="94"><% = rs("点击") %></td>
<td width="148"><% = rs("添加日期") %></td>
</tr>
</table>
<% Rs.MoveNext
Wend %>
</body>
</html>
<% rs.close
set rs=nothing
conn.close
set conn=nothing %>
四、结论
因为这些代码是在服务器端运行的，所以客户端不需要安装任何东西。这仅仅是用ActiveX DLL所能实现的功能的小小的例子。你们可以写好自己的更大的组件,而且还可以用VB中的很多控件。让我们用组件来扩展我们的程序的功能吧!也希望多多的看到我们中国人的组件。但愿本文能起到抛砖引玉的作用。
