版主，你好，FLOGIN。ASPX终于能正常显示用户注册信息了，在此先谢了哦！
但问题还有，就是“修改”功能，也就是注册成功后，点“返回”，回到修改页面（即原来的“注册”），修改注册信息后再点“提交”，得到下面提示，修改当然就没有成功：

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()

 

好像是同WE。CONFIG文件有关，但我看来看去看不出个究竟，现在还是要请版主指点迷津了
