LVM_SORTITEMS
-
Hi, I got a Listview control which is ownerdata driven. I want to sort it but the LVM_SORTITEMS function just fails... I am not sure if it's relevant, but the GetLastError() return that the params are invalid. I checked it 20 times, the compare function is all right (CALLBACK, right params, return... all). I tried passing both NULL and some dummy to as the LPARAM (though it shouldn't ake any difference cause I don't do anything with them later). The HWND is valid and is used before and after this piece of code. The only thing that comes on my mind is that sorting isn't supported with ownderdata, but I haven't found a single line regarding this... Thanks!

With CListBox an owner-drawn list box created w/ style LBS_SORT and items are added to it w/ AddString, then CListBox::CompareItem must be overridden with a version that compares two arbitrary items packaged in COMPAREITEMSTRUCT structures.
