抱歉,我誤會了,
要ASP的嗎?
我以前有用過My 動力管理系統
看到裡面有個亂數數字繪圖的程式
原版是簡體的
我之前有用Word翻譯過了
應該是可以用
可以自訂亂數數字長度
PS : 我之前有稍微接觸過ASP ,有什麼問題..可以再說
-------------------------------------------------------------------------
插入判斷圖片那頁(發表留言那頁)要加入下面的程式碼
預防IE讀到的圖片式舊的
<%
option explicit
'強制瀏覽器重新訪問服務器下載頁面，而不是從緩存讀取頁面
Response.Buffer = True
Response.Expires = -1
Response.ExpiresAbsolute = Now() - 1
Response.Expires = 0
Response.CacheControl = "no-cache"
'主要是使隨機出現的圖片數字隨機
%>
-------------------------------------------------------------------------
-------------------------------------------------------------------------
判斷輸入的是否不一樣
*那個輸入驗證碼的框框 Name 要設CheckCode
<%
CheckCode=replace(trim(Request("CheckCode")),"'","")
if CheckCode<>CStr(session("CheckCode")) then
.....輸入的檢查碼不相同...
%>
-------------------------------------------------------------------------
-------------------------------------------------------------------------
下面開始是圖片產生的程式
把下面原始檔存成 *.asp 然後當做圖片插入應該就可以用了
例如
<img src="rand.asp">
