Unable to altering a list box

Try as I might I have been unable to update the contents of a list box. I have searched and searched to no avail so any help on this would be appreciated.

I have a list box with some values in it.
When I hit "Go" I want to select that entry in the list box

On reading some external documentation LB_FINDSTRING returns LB_ERR which is not defined anywhere. I have added a bug on SF (1771644) which covers it, but it would be nice to know so that I can include it in my installer before your next release.

Aside from the LB_ERR issue which is almost academic because no matter what I do it never works.

Tried of programming by trail and error. 🙁
Help !

Cheers,
David.
