大家好.
我在Visual Studio 2008中有一个问题.我正在制作一个可与数据库一起使用的程序(访问2007)，但它不能完全正常工作.我的问题是，在保存任何内容之前，它必须每次都与数据库连接.如果我构建程序并运行它，则不会出现错误，但它不会在db中保存任何内容.我可以使我的程序始终与数据库连接吗???

为什么?
您不能只在程序开始时打开连接，而在程序结束时关闭它吗?

关于VB.NET和MS Access，有很多可用的教程，例如，参见[ ^ ].

Why?
Can''t you just open a connection, say, at program start and close it at program end?

There are a lot of available tutorials about VB.NET and MS Access, see, for instance [^].

您需要自己做一些研究.

开始于:

ADO.NET概述 [使用具有现有数据的数据集 [

you need to do some research on your own.

Start with:

Overview of ADO.NET[^]

Then try here:

Using a DataSet with Existing Data[^]

specifically look at the link titled: "Updating the Database with a DataAdapter and the DataSet"
