> how can i refresh just one record in a IB_Query?

with IB_Query do
InvalidateRowNum( RowNum );

the above refreshes the current row, replace RowNum with a specific
row if it is not the current row you want refreshed.

You can also use InvalidateRows, which will invalidate all rows, but
they will only be re-read from the server as required (for example all
rows showing on a grid).
