:)那个方法是一样，不是就是麻烦一些而已。服务器会将服务器上显示的所有内容记录在一个叫Log.nsf数据库中，其实方式方法都是一样的，就好像打开控制台上查看结果和跑到服务器上看结果是一样的。

log.nsf的其它事件里也可以看到msgbox的信息。。

对啊，两种方法：
1.js：直接弹出框显示，或用Print直接在页面上显示出来
2.LS:msgbox直接可以从控制台也就是服务器上看到效果的．

代理里面可以用不过不是在页面中弹出来你到你的工作台上就可以看到结果了。

哦，我在代理（Lotus script)里面想alert一个变量Num
print |<script language="javascript">alert（Num);</Script>|

可是好象javascript不认这个变量阿，怎么办呢？谢谢

简单实现文件上传下载，指定服务器，有扩展性

个人初学C#的笔记

整个软件结构包括：升级数据库服务器、升级代理程序、客户端应用程序、升级服务管理程序等。升级数据库器保存各个版本软件的版本、文件名、文件内容等信息；升级代理程序负责读取升级数据库服务器中的最新版本信息和文件信息，完成最新版本下载和更新，并启动客户端应用程序；客户端应用程序为客户端具体应用的程序软件，即为需要实现更新的软件；最新版本上载程序是升级信息管理程序，用于上传最新的版本信息和相应的文件内容。
