如何设置文件的修订号
我在我的项目中使用文件上传。我喜欢为我在数据库中上传的文件设置修订号。即，我将第一次上传 sd.doc 文件，它将保存为版本 1。下载该文件后，我将进行一些更改，并保存它应保存为版本 2。查看时，它应该显示两者版本，我应该根据版本选择文件。任何人都可以帮我解决这个问题。
提前致谢。
I am using the file upload in my project. I like to set the revision number for the file which I am uploading in the database. i.e. I will upload a sd.doc file for first time it will be saved as version 1. After I am downloading that file I will make some changes and I will save that it should be saved as version 2. While viewing it should show both the version and I should choose the file based on the version. Can any one help me to solve this issue.
Thanks in Advance.

如果我正确理解您的问题，您需要文档的版本控制系统。
我能想到的解决方案之一是使用 Mercurial DVS。您可以创建简单的 UI 界面来与其命令行“hg”进行交互。它为您提供了巨大的潜力，很可能您在应用程序中不需要，但保存“修订”号，使其他人能够查询它，所有这一切都已经完成+您将为未来的开发提供大量选项。
但这一切都取决于您的项目要求。密切关注这一点并做出选择。
希望这有帮助。
问候。
If I right understand your problem, you need versioning system for docs.
One of the solutions that I can think off, is using of Mercurial DVS. You can create simple UI interafce to interact with it's command line "hg". It provides to you a huge potential, that most probabbly you will no need in your app, but saving "revision" number, enable others to query it, all this is already done + you will given huge amount of options for future development.
But all depends on your project requirements. Keep an eye on that and make a choice.
Hope this helps.
