This value implies use of $LVFI_STRING. $LVFI_STRING - Searches based on the item text. Unless additional values are specified, the item text of the matching item must exactly match the string pointed to by the Text member. $LVFI_WRAP - Continues the search at the beginning if no match is found LVFI_NEARESTXY - Finds the item nearest to the position specified in the X and Y members, in the direction specified by the Direction member. This flag is supported only by large icon and small icon modes. |
