Delphi Application Architecutre(200分)

Our company's LAN application is running ASP + MS SQL7.0, but is considered to be re-developed using Delphi 6.

We have 6 data-entry operators, including 2 working from home through VPN (virtual private network). Users access the database through internet explorer. We have recently purchased Delphi 6 (professional version), and would like to make the application more user-friendly, and more interactive.

Questions are:

1.Would it be possible to set up Delphi application running on internet explorer, so that users can access the database through browsers? (I have done some research, and it seems to me that with PROFESSIONAL version, we can only create normal executable application. I am not sure if I am wrong)

2.If we create normal executable application (not running on IE), how should I distribute the executable file to different users (especially the external users via VPN), and how to manage the version control for any changes we do later on?

3.Can I allow the users to share the same executable file (on the server) by running a shortcut on their desktop (which points to the central executable file)?

4.Any better suggestions?

Hopefully I have made the questions clear, Thank you very much in advance!
Happy Programming!

真是个懒人！

1，嵌入IE可以用ACTIVEFORM，开发过程和一般的应用程序没有什么大的不同。（你先问一下BORLAND专业版支不支持ACTIVEFORM）
2，版本升级后，只能通知他们单独下载了。或在你的程序里加一个判断，每次启动时都先连接服务器，发现服务器上的版本更新时，自动下载。
3，可以。只要你给他们权限。
4，祝你好运。

1.You can compress your application as activeX ,regedite it and then
you can use it in IE.
2.You may decleare a string.It's your version .The rest is .....It's up to you.
3.Yes ,you can share it,but maybe you will setup bde on the client.
