I have a list view control (actually several) whose definition looks like this:

Never mind! I found the post from 2009 that discussed this and I see the issues with both my code and the control!

I did a search on the term "listview".

If you allow multiple selections, then the selection made will not necessarily show in the display area. I understand why that is: Do you display the first or last one? No real way to do this automatically, only programmatically.

One can select the one you wish by using a simple routine. You'll need to get the handle of the list view control using the %lc command, then call this routine with the handle and the item number (1,2,3,...) to be displayed.

z'1000' is the hexadecimal constant. The LVM_* commands all start at Z'1000'.

This is the same as 4096.

Again, if you make the first appear as the default, then how do you make the last appear?

Better to not make any appear if multiples are permitted and use this little ditty to show the one you want.

That is a valid point; yet, one is still the programmer and can make that decision better for the applications purpose.

For example, I allow the user to select a disconnected list of items to edit, with an option to stop editing whenever they chose. I will highlight the last one they edited, or the last one in the list.

I also allow the user to select a disconnected set of items for deletion. I select the line closest to the first in the set, just as a default.

I could have chosen the opposite way as well. This just made sense to me based on the data presented and how the user interacts with it.
