This should be dead simple - I have a BO called boAllPeople with a data access method called GetAllPeople():

public void GetAllPeople()

{

SqlCommand loCommand = new SqlCommand();

loCommand.CommandType = CommandType.StoredProcedure;

loCommand.CommandText = "prcListAllPeople";

this.FillDataTable(loCommand);

}

Here is the code in prcListAllPeople:

At least this time something new happened. I got an error:

ArgumentException
  Object of type 'TGIF.BusinessObject.boAllPeople' cannot be converted to type 'System.Data.DataTable'.
