'VB.Net ConnectionString with a local .mdf database
I am publishing a project application and I think having a connectionstring with this format
cn.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Documents and Settings\iaprubillos\My Documents\PROJECT\myProject\database\myDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
is not a friendly and definitely won't work when I will run the application on other computers. Question: Can I use a connectionstring in a format of
cn.ConnectionString = "Data Source=|DataDirectory|\myDatabase.mdf"
and store the database in bin folder so that when I Build my project and compile to an .exe file, the .exe file can still access the database?

You can use My.Application.Info.DirectoryPath to get the path where your application is running from. So you can modify your connextion string code like this:
cn.ConnectionString = String.format("Data Source=.\SQLEXPRESS;AttachDbFilename={0}\myDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True", My.Application.Info.DirectoryPath)
