SQL Invalid Object Name 'AddressType'

I am getting the above error in my VS 2008 C# method when I try to invoke the SQL getColumnNames stored procedure from VS. This SP accepts one input parameter, the table name, and works successfully from SSMS. Currently I am selecting the AdventureWorks AddressType table for it to pull the column names from this table. I can see teh AdventureWorks table available in VS from my Server Explorer / Data Connection. And I see both the AddressType table and getColumnNames SP showing in Server Explorer.

But I am still getting this error listed above. Here is the C# code snippet I use to execute this:

public static DataTable DisplayTableColumns(string tt) { SqlDataReader dr = null; string TableName = tt; string connString = "Data Source=.;AttachDbFilename=\"C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\AdventureWorks_Data.mdf\";Initial Catalog=AdventureWorks;Integrated Security=True;Connect Timeout=30;User Instance=False"; string errorMsg; SqlConnection conn2 = new SqlConnection(connString); SqlCommand cmd = conn2.CreateCommand();

    try
    {
        cmd.CommandText = "dbo.getColumnNames";
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Connection = conn2;
        SqlParameter parm = new SqlParameter("@TableName", SqlDbType.VarChar);
        parm.Value = TableName;
        parm.Direction = ParameterDirection.Input;
        cmd.Parameters.Add(parm);
        conn2.Open();
        dr = cmd.ExecuteReader();
    }
    catch (Exception ex)
    {
        errorMsg = ex.Message;
    }

And when I examine the errorMsg it says the following:

"   at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)\r\n

Where line 35 is

dr = cmd.ExecuteReader();

I quickly checked AdventureWorks database and see that the table "AddressType" belongs to the schema "Person". Try passing "Person.AddressType" as the value of the value of the command parameter in the code.
