小弟想问一下:
ActiveForm是干什么用的? 和普通Form有何区别? 小弟翻了一些书,上面没有介绍。

小弟初涉此行,真的不明白,盼那位能讲解一下,越详细越好,我是小学生一个。

D6生成的ActiveForm的代码如下:---
unit ActiveFormImpl1;

是一个activeX,可以显示在浏览器中
 
是为了支持该死的M$的activex技术
 
你可以将它当成TFORM一样的东西来开发,
但它有一个好处就是,它可以发布到WEB上,客户端用IE观看。
之所以这样做是BORLAND公司为了方便开发人员将现有的的程序,用最小的花费
将程序做成WEB版(这句说得不好)
在网络上支持PUSH,PULL技术。
 
它其实是一个ActiveX,是一个容器,在它上面放入一些控件,并执行一些操作,封装后
生成ActiveX控件,便可以在网上发布了,现在有很多单位有ActiveForm设计程序,
通过IE动态下载,安装和维护比较容易。
 
ActiveXForm可以在IE中顯示,用來開發B/S架構的程序
 
在上面放上东西,你的程序就可以在Web上跑了!
 
多谢楼上各位 小弟现在有了基本的概念了
 
还不结束?
 
再说说吧

怎样把ActiveXForm发布成WEB页? 用不用CGI的东东?
 
不用,用project-->web deploy
 
project-->web deploy中的几个选项和EDIT框是作什么用的?

有没有这方面的书籍? 我想看看
 
一般的书上都有。
delphi3.0入门与提高。
 
谢谢各位!
结束此贴!
