本程序分兩部分：
1,、ASP文件打包程序pack.asp
 把這個(gè)程序和要打包的程序放到一個(gè)目錄下,，然后運(yùn)行pack.asp，得到pack.jpg和config.txt
2,、ASP在線更新,、下載、安裝程序updata.asp
 這個(gè)程序可以用來(lái)檢查是否存在可用更新,，和updata.asp同一目錄要存在上面得到的config.txt,，因?yàn)閏onfig里面有當(dāng)前程序的安裝日期，用來(lái)和網(wǎng)上的程序比較用的,。
 使用前,，先修改updata.asp里的url變量的值，使其等于你存放升級(jí)程序的URL,，運(yùn)行updata.asp就可查看是否存在可用更新,，如果存在就可用按著向?qū)б徊揭徊较螺d并安裝更新了。

遠(yuǎn)程地址url下面存放用pack.asp得到的pack.jpg和config.txt
