记账软件版1楼: 1. 要求可以新建
2. 点击控件的时候，有象delphi设计界面上一样，在控件四个角上有小黑点
3. 可以保存控件位置，下次运行自动产生控件

以前见过一个极酷的仿Delphi开发环境的DEMO，不知道谁有，可否恭喜一下，给个下载地址研究研究！

2楼: 这个应该保存到流中
启动程序时,从流中读出来 如进销存系统源码

3楼: 有程序運行時設計控件，像在DELPHI設計時一樣具有各項屬性。

4楼: to bbscom ： 能具体点吗？不知道从哪里查起？

5楼: 自已用代码已实现；并且是将信息保存到后台数据库中；

6楼: 找个地方存放这些控件的类型 font caption left top height width 等等信息，然后根据这些信息，在显示窗体前，动态生成控件。

记账软件版7楼: 看我的：

8楼: 试试 hhjjhhjj 的代码

9楼: 测试了 代码，在移动 SpeedButton1 时候，会不见了几个 小黑点

10楼: 帮顶！
