create setup package

hello my friends. here is my questions

1)
i have made an application with a database.

i have made a win application with a database included. i wite the code using datasets,datatables etc... if i want to see the new datas in a table i have to reload the MyDatabase.mdf file in order to see them if i save datas when i run the application, so if i make a setup.exe for this app when i run it and do some sabes in the database will iu be able to see them in the app??


2)
i created an setup.exe

but when i fire tha icon to run it it says something about the database


"An attempt to attach an auto-named database for file C:\Documents and Settings\Administrator\My Documents\Visual Studio 2005\WebSites\WebSite1\App_Data\aspnetdb.mdf failed. A database with the same name exists, or specified file cannot be Opened, or it is located on UNC share."

any suggestions???

thank you
