textfile - 写入文件的开头？ [英] textfile - write to beginning of file?

问题描述

嗨 - 来自相关asp新手的问题


我过去曾写过文本文件，但总是追加新数据

结尾文本文件。我现在想要将新数据添加到

文件的开头。


文本文件将是通过Web表单下达的订单记录。

文本文件只是订单的记录，但它需要在

降序日期顺序中 - 每个新记录都添加到开头。


提前感谢任何关于如何实现的建议。

是有没有理由你没有使用数据库？


如果是这样，那么XML将是一个更好的解决方案。


一个文本文件是非常有限。

你好安东尼


我不会使用数据库，因为它没有'看起来不值得。这个文件唯一的原因是因为一个组织内的几个人可以放置

我认为写入XML文件会遇到同样的问题，因为它是

真的只是一个文本文件，但也许我正在接近这个错误。


非常感谢您的关注和帮助。

无法完成。您将不得不创建一个新文件，将新内容写入其中，读取旧文件并将该数据放在新文件中。然后

删除旧文件，并重命名新文件。

Hi - question from a relative asp novice

I have written to text files in the past, but always appending new data to
the end of the text file. I now want to add the new data to the beginning of
the file.

The text file would be a record of orders placed through a web form. The
text file would merely be a record of the orders but it needs to be in
descending date order - each new record added to the beginning.

Thanks in advance for any suggestions as to how this is achieved.

Is there a reason you are not using a DB for this?

If so then XML would be a better solution.

A text file is very limiting.

Hi Anthony

I wasn''t going to use a DB because it didn''t seem worth it. The only reason
for the file is because several people within an organisation can place
orders and each needs to check that some-one else hasn''t recently ordered
the same item for the firm.

I assumed that I would have the same problem writing to an XML file as it is
really only a text file but perhaps I am approaching this wrongly.

Thanks very much for your interest and help.

John

Can''t be done. You''ll have to create a new file, write the new stuff
to it, read the old file and put that data on the new file. Then
delete the old file, and rename the new one.
