慈铭体检中心电话:ASP的验证码代码怎么写？

因为字符限制原因,不好粘贴代码,生成验证码的程序粘贴不上来,你把邮箱告诉我,我发你邮件.

以下是一个完整的验证码生成程序,生成的是一张图片.
然后你在其他页面里调用这张图片就可以了.

调用程序如下:

<td colspan=2> <span class="new">验证码:</span>
<input name="verifycode" type=text id="verifycode"><img src=verifycode.asp></td>

验证码生成程序粘贴不了.
你把以下地址的程序存成verifycode.asp就可以了

<%
