combobox

I created a combobox in a form (style=dropdown combo). user can input
his own text or select from an existing one.

I entered some text into it. After a thisform.refresh(), the
combox.value was cleared. Why? how could I keep the user-inputted value
persistent?

As a result, I couldn't save the value to the combobox.controlsource.

The underlying table is having buffering=5.

Right, you'll need to add the new value to combo.RowSource. Since there is
no built-in automatism, you can do so manually - e.g. in pseudo code:
* combo.Valid
IF !(This.Value == This.DisplayValue)
DO CASE
CASE INLIST(This.RowSourceType, 0,1)
This.AddItem(m.tcNewItem)
CASE This.RowSourceType = 2
INSERT INTO ( GETWORDNUM(This.RowSource,1,'.') ) ;
( GETWORDNUM(This.RowSource,2,'.') ) ;
VALUES (This.DisplayValue)
Case ...

I got it.... I thought it would work like a normal textbox when the
style is a "dropdown combo".
