How to make Sharepoint "link" execute an ASP.Net application (.aspx file)?

Hello Community

    Using Sharepoint 2010 server I use links (ie http://...).

    There are batch files I need to run so I cannot execute the .bat file
from inside a Sharepoint in a link.

    Instead I created a simple ASP.Net/C# program using Visual Studio 2008
that will execute the .bat file.

    I compiled it ran fine showing 'http://<localhost:portnumber>/<appname.aspx>'
in the address bar after it runs.

    So I copied the url out of the address bar and pasted it into the link inside
Sharepoint 2010 Server and click the link.

    That is where the problem came in, the application returned an error page stating:

 "this page can't be displayed"
        "make sure the web address http://<localhost:portnumber> is correct"
        "etc.

    The Sharepoint link seemed to work, it looks like the problem is apparently that
there is more to the ASP.Net being compiled running.

    What do I have to do so that the link in Sharepoint can execute the ASP.Net
web application?

    Thank you
