Hi, I was wondering how can I display a certain index in a combo box to show up after I click a button. For eg: a combo box has values 0) Water 1) Rice 3) Curry and the default value is set to "". So, when I click a button how can I make any one of three show up? Also, where can I find API documentation for Access programs coz without it, its like walking in a dark unknown field. thanks..
