Logic is:
1. Have list box with tables from db
2.click on it and fill ListView with list of columns and stuff from selected table.
So, Application.ProcessMessages; should not do any difference, since I can't click fast enough and I don't, to reload faster than previos process ends, only few items are cleared/added to ListView for each refill.
