Hello Larry.

I'm using a public array as the row source.

Tsk, tsk, tsk. It would be a lot better if you added an array property to your combo box class and used that as its RowSource. JMHO.

the data only gets saved if I select a value from the array. If I type in a value that isn't, it doesn't save. Am I using this control wrong, or are there additional setup paramaters I'm missing.

You have to take some action to add the value to the control's RowSource whent he user types in something that is not in the list. Code like this, in the combo's valid, will do it for you:

WITH This
  IF NOT EMPTY( .DisplayValue ) AND .ListIndex = 0
    lnLen = .ListCount + 1
    DIMENSION .aContents[ lnLen ]
    .aContents[ lnLen ] = .DisplayValue
    .Requery()
   ENDIF
ENDWITH
