Referencing SQL Database Location in VB 2008

How can I replace the C: reference line below?
I have a procedure that works, but needs to be adjusted in order to handle future use when a user has the program and database installed in a different location on another computer.
This part below in Code sample
                              =C:\CompanySetup.mdf
is the part I need to be a variable since it will not always be on the C:\  folder.  My VB Database reference are:
        ' CompanyInfoBindingSource
        ' CompanyInfoTableAdapter
        ' CompanySetupDataSet.CompanyInfo
        ' TableAdapterManager1
Thank You

        Dim myConnectionString As String = _
            "Data Source=.\SQLExpress;AttachDbFilename=C:\CompanySetup.mdf;Integrated Security=True;User Instance=True;Trusted_Connection=Yes;"
              Using connection As New SqlClient.SqlConnection(myConnectionString)
            connection.Open()
 
            Using command As New SqlClient.SqlCommand("StoredProcedure1", connection)
                command.CommandType = CommandType.StoredProcedure
                ' pass parameter - All records matching this project name will be deleted
                command.Parameters.Add("@Proj_NameLookUp", SqlDbType.Text).Value = PDF_ML_Form.PDF_Proj_Name_lbl.Text
                command.ExecuteNonQuery()
            End Using
        End Using
 
    End Sub

in your project properties, go to the settings tab and enter a key name (eg: connString) and the value (Data Source=.\SQLExpress;AttachDbFilename=C:\CompanySetup.mdf;Integrated Security=True;User Instance=True;Trusted_Connection=Yes;")
 Then all you have to do to get the value is :
My.Settings.connString
 If you need to change it then you can do so in the config file and won't have to recompile the application.

I placed the new variable into the settings tab and changed the line to:
      Dim myConnectionString As String = My.Settings.connString

Question Please: You said 'If I need to change it'
I want the program to change it during the installation process.  Will the new variable connString  change automatically now depending where the program installs it?  If not it is the same fixed location string in a different place.

Here is how you can create a custom action:

Once you have the install location you can just set the settings value the same way you access it.
