pListboxInfo (PLBOXINFO)
papszText (PSZ *)
This parameter is a pointer to an array of pointers to zero-terminated strings. The array must contain at least ulItemCount items. (ulItemCount is a field in LBOXINFO.)
If this parameter is set to NULL, a ulItemCount number of empty items are inserted into the list. This is useful for ownerdraw listboxes that do not make use of text strings.
lCount (LONG)
If the number of items is not the same as ulItemCount, an error has occured.
