Actually I’m working on an Asp.Net three-tier architecture project. When I try to
write code for the data access layer I’m getting the error below. Please help. (email removed)

public int insertlogin(DataContainer objdc,string CmdText)
{
    Util.Open();
    SqlCommand Cmd = new SqlCommand();
    Cmd.Parameters.Clear();
    Cmd.Connection = Util.SqlCon;
    Cmd.CommandType = CommandType.StoredProcedure;
    Cmd.CommandText = CmdText;
    Cmd.Parameters.Add("@id", SqlDbType.Int).Value = objdc.id;
    Cmd.Parameters.Add("@username", SqlDbType.VarChar, 50).Value = objdc.username;
    Cmd.Parameters.Add("@password", SqlDbType.VarChar, 50).Value = objdc.password;
    Cmd.ExecuteNonQuery();
    Util.Close();
}

You haven't returned anything from the routine (needs to return an int value)

public int insertlogin(DataContainer objdc,string CmdText)
{
    Util.Open();
    SqlCommand Cmd = new SqlCommand();
    Cmd.Parameters.Clear();
    Cmd.Connection = Util.SqlCon;
    Cmd.CommandType = CommandType.StoredProcedure;
    Cmd.CommandText = CmdText;
    Cmd.Parameters.Add("@id", SqlDbType.Int).Value = objdc.id;
    Cmd.Parameters.Add("@username", SqlDbType.VarChar, 50).Value = objdc.username;
    Cmd.Parameters.Add("@password", SqlDbType.VarChar, 50).Value = objdc.password;
    Cmd.ExecuteNonQuery();
    Util.Close();


    int loginReturnValue = 0; // Populate whatever the return value should be? 
    return loginReturnValue;
}
