Cannot find database

Question

Hi,

I've created a database using this Stored Procedure.

ALTER PROCEDURE dbo.StoredProcedure1
    (
    @DatabaseName    VARCHAR(50) = 'SampleDB'
    )
AS
BEGIN
    SET NOCOUNT ON
    EXECUTE('CREATE DATABASE ' + @DatabaseName);
END

Executed it in ASP.net web page

SqlConnection con = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=<local computer path>\App_Data\ssdb_main.mdf;Integrated Security=True;User Instance=True");

        con.Open();

        SqlCommand dbc = new SqlCommand("StoredProcedure1", con);
        dbc.CommandType = System.Data.CommandType.StoredProcedure;

        dbc.Parameters.Add(new SqlParameter("@DatabaseName", "MyNewSampleDB"));

        dbc.ExecuteNonQuery();

        con.Close();



It executed successfully but I cannot find the database. I rerun it and it says it that the database has already existed? Where can I find it? I tried in C:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\DATA AND C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA but the database is not in there..

Help anyone?

Thanks
