How can I receive the list of table names in ADO?

Answer:

If you needs to retrieve the list of available tables in ADO, you can call the 
GetTableNames method of your TADOConnection component: 
1   
2   {we want to receive the tables including the system tables}
3   boolSystemTables := True;
4   yourADOConnection.GetTableNames(yourListBox.Items, boolSystemTables);

if you want to recieve the names of stored procedures, you must call the 
GetProcedureNames method: 

yourADOConnection.GetProcedureNames((yourListBox.Items);
