Getting new value of listview selection...

[Anonymous]

I'm having problems getting the new value of a listview selection.  I want to update other controls on the form based on the new row selected in the listview (whether by mouse, keyboard, etc.)

I tried LVN_ITEMCHANGED and LVN_ITEMCHANGING, but they are not giving me consistent values.  I also searched PB and here and found ListView_GetSelectionMark, but this seems to have the same problem.

This is the code that isn't working for me right now.  I didn't save the many other things I've tried.

Any suggestions?

Thanks!

Thanks Roger!

I put that in LVN_ITEMCHANGED and it works perfectly!

Cool, the other common one I use is LVNI_FOCUSED if the item is in a multi selection list, or you could continue searching from the found location and gather all those selected.
