I have a working search routine which I would like to have filtered and have no idea where to start with it.
My idea is that I would like only to populate the listbox with results where worksheet rows have no data in all four of columns 10, 12, 13 and 14. Currently data is returned from all rows but the listbox results are only used for the updating of one or more of those four columns.
As I am almost entirely new to programming of this type I don't even know if it is more efficient to narrow the data for the search or to perform the search and narrow the results so any help would be appreciated.
Thank you in advance.
