会话状态问题 [英] Session state problem
问题描述
我有一个特殊的问题。我有一个简单的Web应用程序，从oracle表中加载一些数据，并在
网页的datagrid中显示，datagrid已启用页面，在页面上显示10行.I
有一个搜索条件来根据数据范围搜索记录我
给
这就是我所做的，在！IsPostBack部分。我正在设置
oracle连接，创建数据集对象，datadapter和我aslo
将数据库中的数据加载到数据集中并移动所有数据集，
datadapter，以及会话对象的连接对象。现在用户可以用记录进行不同的操作，比如他从网格中选择一行并且
网格列中有按钮进行更新，所以我这样做，
更新该特定行的数据集对象，然后当下一次调用时间页加载时，我调用dataadapter.update来更新数据
回到数据库。所以我的dataproviders对象存储在
会话对象中。首先，它是一个很好的方法吗？
会话结束时的第二个，如果用户回来并做了一些
操作，它无法更新，因为会话变量
被销毁，并且会产生错误。我该怎么做才能解决这个问题？
这个问题？或者如果会话对象不是存储这个
dataprovider对象的好地方，那我应该存储哪些？我的页面没有
用户登录，我只是使用asp.net创建的默认会话。
请帮帮我，非常紧急

>首先，它是一个很好的方法吗？
我们可以在那里停下来，因为不，这不是一个好方法。它听起来像是来自ASP背景，其中连接池
不是平台的一部分。使用ASP.Net，最好打开并尽快关闭你的Connections，然后将它们释放回
池。

感谢您的回复。你能更多地阐述我想做的事情吗？我
也没用过asp，这是我第一次使用
一些webapplication。
你能告诉我吗？我更详细的我想做什么或一些样品
代码？

精心制作？好吧，当你想使用你的数据库时，打开一个
连接，做你的工作，然后立即关闭它。
你可能想创建一个每当您需要连接到数据库时，您可以使用的静态数据库实用程序函数类。我相信微软
可以提供其中一些，虽然我不知道在哪里（我自己写的）。
希望这里的其他人可以告诉你。

I have a peculiar problem. I have a simple web application which loads
some data from the oracle table and display in the datagrid in the
webpage and datagrid has page enabled which shows 10 rows at a page.I
have a search criteria to search the records based on the data range i
give
This is what i have done, in the !IsPostBack section. I am setting up
the oracle connection, creating dataset object, datadapter and i aslo
load the data from the database into dataset and move all dataset,
datadapter, and connection object to session object. Now user can do
different operations withe records, like he select a row from grid and
there is button on in column of the grid to update , so what i do ,
update the dataset object for that particular row and then when next
time page load is called, i call dataadapter.update to update the data
back to the database. so my dataproviders objects are stored in the
session object. First of all is it a good way to do this?
Second when the session ends, and if the user comes back and does some
operation, it going to fail to update because the session variables
are destroyed and it will generate an error. What should i do to solve
this problem? Or if session object is not a good place to store this
dataprovider object, where shoould i store?. My page doesn''t have a
user login, i am just using the default session created by asp.net.
Please help me, its very urgent

We can stop right there, because no, it is not a good way to do this. It
sounds like you''re coming from an ASP background, where Connection Pooling
was not part of the platform. With ASP.Net, your best bet is to open and
close your Connections as quickly as possible, to release them back into the
pool.

Thanks for replying. Can you eloborate more what i am suppose to do? I
never worked on asp either, this is the first time i am working with
some webapplication.
can you tell me more in detail what ia m suppose to do or some sample
code?

Elaborate? Well, when you want to work with your database, open a
Connection, do your work, and close it immediately.
You may want to create a class of static database utility functions that you
can use whenever you need to connect to your database. I believe Microsoft
makes some of these available, although I''m not sure where (I wrote my own).
Hopefully, someone else here can tell you that.
