IBO 4.5B

I have a TIB_IncSearch component hooked to a TIB_Query. the
IncSearch.Ordering link is blank so it searches on the orderinglink
column.

The control is used to lookup values from various tables. The
client types in their beginning search, say "JOHN" into the main
form and this triggers this form to popup with a lookup table.

I want to insert the "JOHN" into the search criteria of the Query.
How do I do this?

I can do the IncSearchString method of a TIB_BDataset, and this
works but it leaves nothing in the search buffer, so the next letter
typed into the IncSearch starts a new search.

TIA,

Rick
