What do you mean when say about another dot net application? You want to integrate qvw document in another application? If so, you need to use QlikView OCX integration, which you can download from http://global.qlik.com/download/
If you could download and install the OCX you get the required document in default folder itself. But only if you are a partner you will get the download access or else you need to contact qlikview to enable the downloads as currently non partner have access only to personal edition.
