这个问题究竟怎么解决啊？
网页连入数据库后在浏览器预览时就产生下面问题：
System.Exception: This page has a MM:DataSet, MM:Insert, MM:Update or MM:Delete tag with a null or empty value for the ConnectionString and DatabaseType attributes.
Often, such values come from application settings in the web.config file. That file might be missing from the server executing this page. Or, it might be missing the particular add key tags for the database connection this page uses. If you are using Dreamweaver, look for the web.config file in the local root folder of your Dreamweaver site. Once you find this file, you can either:
Put this file onto the server that is executing this page.
Copy the add key tags from the web.config in the local root folder of your Dreamweaver site and paste them into the web.config file in the server that is executing this page.
at DreamweaverCtrls.DataSet.DoInit()
在我电脑里就搜索不到Web.config文件，有没有办法？
[解决办法]
如果找不到Web.config这个文件，试着从其他机器上拷贝一个放到你的Dreamweaver 网站的根目录中。
