I am now confused about component QvDatasouce.

At first time,I choose a qvw file and browse application structure, and it works well.

However when I choose another qvw file even I create a new qvDatasouce,I still can't get application structure

If I click "Force refresh",it gets an error message "您的主机中的软件放弃了一个已建立的连接"

 How to solve this, Thanks.

 i think you need to put your 2nd qvw files into the default folder defined in your QVS in order to have different data sources on the same page.
