<head>

}
</style>
</head>
<body bgcolor="#ffffff">
<table width="531" border="0" align="center" cellpadding="0" cellspacing="0">
<!--DWLayoutTable-->
<!-- fwtable fwsrc="未命名" fwbase="register.jpg" fwstyle="Dreamweaver" fwdocid = "1502317357" fwnested="0" -->
<tr>
<td width="58" rowspan="5" valign="top" bgcolor="#D8FBB5"><img src="spacer.gif" width="58" height="1" border="0" alt="" /><img name="register_r1_c1" src="register_r1_c1.jpg" width="58" height="74" border="0" id="register_r1_c1" alt="" /><img name="register_r2_c1" src="register_r2_c1.jpg" width="58" height="48" border="0" id="register_r2_c1" alt="" /><img name="register_r3_c1" src="register_r3_c1.jpg" width="58" height="202" border="0" id="register_r3_c1" alt="" /><img name="register_r6_c1" src="register_r6_c1.jpg" width="58" height="53" border="0" id="register_r6_c1" alt="" /></td>

二、建立连接并打开数据库的子程序con1.asp
复制代码 代码如下:
<%
'字符串连接数据库的方法
set conn=server.createobject("adodb.connection")
conn.Open "DRIVER=Driver do Microsoft Access (*.mdb);uid=admin;pwd=;DBQ="&server.MapPath("regdb1.mdb")
%>
三、建立ACCESS数据库db1.mdb，在其中建立数据表user,字段分别为：u_uid（自动），u_user（用户名：文本型），u_pass(密码：文本型)
四、建立接收register.asp中发送过来的表单数据，并插入到数据表user中的注册成功显示页面：result2.asp代码如下：
复制代码 代码如下:
<%@ language=vbscript %>
<!-- #include file="con1.asp"-->
<html >
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>注册成功</title><br>
</head>
<body>
<%
'建立recordset对象方法
set rst=server.createobject("adodb.recordset")
set rst1=conn.execute("insert into user (u_user,u_pass) values('"&request.form("u_user")&"','"&request.form("u_pass")&"')")
%>
<table width="300" border="0" align="center">
<tr>
<td align="center"><img src="chenggong.jpg" alt="注册成功" width="297" height="201"></td>
</tr>
</table>
</body>
</html>
五、按F12预览register.asp并输入数据，点击提交按钮
这时打开数据表user会看到：
说明操作成功，因为已经提交两次，所以我们看到表中插入了两条新的记录，但是表中出现了重复记录，以下在result2.asp中添加代码予以解决：
复制代码 代码如下:
<%@ language=vbscript %>
<!-- #include file="con1.asp"-->
<html >
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>注册成功</title>
<style type="text/css">
<!--
.STYLE1 {font-size: 24px}
-->
</style>
<br></head><body>
<%
'建立recordset对象方法
set rst=server.createobject("adodb.recordset")
rst.open"select * from user where u_user='"&request.form("u_user") & "'",conn,1,1
if rst.recordcount>0 then
response.write"用户名："&request.form("u_user")&"已被占用，请点击返回重新注册"
%>
<a href="register.asp" class="STYLE1">返回重新注册</a>
<%
response.End
else
set rst1=conn.execute("insert into user (u_user,u_pass) values('"&request.form("u_user")&"','"&request.form("u_pass")&"')")
end if
%>
<table width="300" border="0" align="center">
<tr>
<td align="center"><img src="chenggong.jpg" alt="注册成功" width="297" height="201"></td>
</tr>
<tr>
<td align="center"><a href="register.asp" class="STYLE1">返回</a></td>
</tr>
</table>
</body>
