  作用:用ASP程序将页面中的电话号码生成图片格式。
复制代码 代码如下:
<%
Call Com_CreatValidCode(Request.QueryString(tel))
Public Sub Com_CreatValidCode(pTel)
----------禁止缓存
Response.Expires = 0
Response.AddHeader Pragma,no-cache
Response.AddHeader cache-ctrol,no-cache
Randomize
Dim i, ii, iii ,rndColor,strLen,sql,rs
Const cOdds = 5 ------------杂点出现的机率
Const str=0123456789-
strLen = len(pTel)
rndColor = ChrB(cint(rnd*255)) & ChrB(cint(rnd*255)) & ChrB(cint(rnd*255))
-----------颜色的数据(字符,背景)
Dim vColorData(1)
vColorData(0) = ChrB(0) & ChrB(0) & ChrB(0) ----蓝0,绿0,红0(黑色)
vColorData(1) = ChrB(255) & ChrB(255) & ChrB(255) ----蓝250,绿236,红211(浅蓝色)
vColorData(0) = ChrB(197) & ChrB(106) & ChrB(49) ---- 蓝0,绿0,红0(黑色)
vColorData(1) = ChrB(238) & ChrB(210) & ChrB(193) -----蓝250,绿236,红211(浅蓝色)
vColorData(0) = ChrB(0) & ChrB(0) & ChrB(0) ---------蓝0,绿0,红0(黑色)
vColorData(1) = ChrB(205) & ChrB(237) & ChrB(245) ------------蓝250,绿236,红211(浅蓝色)

将以上代码保存为img.asp,在要显示电话号码的位置插入<img src=img.asp?tel=010-0000000>即可。
