Traversing the data set to go, probably code:

 ComboBox - & gt; The Items - & gt; The Clear (); 
. 
ADOQuery - & gt; The Open (); 
for (int i=0; I & lt; ADOQuery - & gt; RecordCount. I++) 
{
ComboBox - & gt; The Items - & gt; Add (ADOQuery - & gt; FieldByName (" field name ") - & gt; AsString) are identical. 
ADOQuery - & gt; The Next (); 
} 
.
