Another listbox problem

[NoCforMe]

Just had a flash (or a brain fart?): since a listbox control contains lines of text, it can only be sized in increments of those lines. So that's why its size "jumps" when it's resized.

Is this correct?

I'll take you up on your offer, jj.

Minor suggestions. Your prog works fine. Re performance, there is obviously a problem - it loads in about 12 seconds on my P4. A factor 60 compared to 0.2 seconds for reading & sorting the file with MB Recall & QSort.
