⑸.修改類代碼如下:
from www.49028c.com
'建立數據庫連接并輸出數據庫字段 Dim Response As Response Dim Request As Request Dim Server As Server Dim application As Application Dim session As Session
Private Sub Class_Initialize() Dim objContext As ObjectContext Set objContext = GetObjectContext() Set Response = objContext("Response") Set Request = objContext("Request") Set Server = objContext("Server") Set Application = objContext("Application") Set Session = objContext("Session") End Sub
Sub conn_db() Set conn = CreateObject("adodb.connection") conn.open "course_dsn", "course_user", "course_passWord" Set rs = CreateObject("adodb.recordset") rs.open "select * from user_info", conn, 1, 1
If rs.recordcount > 0 Then For i = 1 To rs.recordcount Response.write "<br>" & rs("user_name") & "<br>" If rs.EOF Then Exit For rs.movenext Next End If rs.Close Set rs = Nothing conn.Close Set conn = Nothing End Sub
⑹.添加一新類cutstr
⑺.修改類代碼如下:
'截取字符串 Function cutstr(str, length) If Len(str) > length Then cutstr = Left(str, length) & "..." Else cutstr = str End If End Function
⑻.File>>Save
⑼.File>>make course.dll
3. 注冊組件:MTS和regsvr32.exe
有兩種方式注冊組件:MTS和使用regsvr32.exe。MTS是值得推薦的,因為它具有下列優點: n 動態卸載平衡,提高組件和基于組件的應用程序的升級性。 n 包含公布和提交事件和隊列組件的能力,使得更容易與多個組件聯合。
要想使組件具有MTS的特性,必須對組件做少許改動。在NT和98下開發時,必須在項目中引用Microsoft Transaction Server Type Library,在Windows 2000下開發,必須引用COM+ Service Type Library。
asp_use_com.asp <% 'asp調用com組件 set cutstr_obj=server.createobject("course.cutstr") response.write cutstr_obj.cutstr("abcdefghijk",3)&"<br>" set cutstr_obj=nothing
set conn_obj=server.createobject("course.conn_db") conn_obj.conn_db() set conn_obj=nothing %>
使用Microsoft Smtp發送電子郵件 ⑴.安裝Microsoft SMTP Service ⑵.設置Microsoft SMTP Service ⑶.代碼部分: mail_smtp.asp <% sub sendmail(fromwho,towho,subject,body) dim mymail set mymail = server.createobject("cdonts.newmail") mymail.from = fromwho mymail.to = towho mymail.subject = subject mymail.body = body mymail.send set mymail = nothing end sub %>
該子程序接受4個與下列各條對應的參數。 l 郵件發送者的email地址 l 郵件接收者的email地址 l 郵件主題 l 郵件內容
使用方法: <% fromWho=… toWho=… Subject=… Body=…
IF toWho <> "" THEN sendMail fromWho, toWho, Subject, Body END IF %>

Sub instead(word) Set myRange = word.ActiveDocument.Content for i=0 to Var_Num - 1 call myRange.Find.Execute(varStrings(i),false,false,false,false,false,false,false,false,varValues(i),2) Next End Sub
w1="word.activedocument.saveAs"&chr(32)&chr(34)&filenames&chr(34) w2="wApp.Documents.open"&chr(32)&chr(34)&filenames&chr(34) %> <script language="vbscript"> On Error Resume Next '生成指定文件名的Word文檔 Dim word set word = CreateObject("Word.Application") if Err.number > 0 Then Alert "發生錯誤,請確認文件是否存在" else word.visible = False word.documents.open "<%response.write path%>course.dot" <%Response.write w1%> word.documents.close set word=nothing end if
<!--#include file="opr_doc_inc.asp"-->

附: 1.以上全部代碼在Windows 2000 Server SP2+IIS 5.0+MS SQL Server 2000+Office 2000下測試通過 2.配置數據庫:數據庫名course,用戶course_user,密碼course_password,ODBC驅動為course_dsn,端口為2433,描述表結構的腳本在共享目錄下。 3.Asp fileup、Jmail、Winzip 8.1、Winzip command line這幾個軟件請自行下載。 4.數據庫腳本文件: if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[output_1]') and OBJECTPROPERTY(id, N'IsProcedure') = 1) drop procedure [dbo].[output_1] GO
