LB_FINDSTRING

An application sends an LB_FINDSTRING message to find the first string in a list box that contains the specified prefix.

LB_FINDSTRING

wParam = (WPARAM) indexStart; // item before start of search

lParam = (LPARAM) (LPCTSTR) lpszFind; // search string address

Parameters

indexStart

Value of wParam. Specifies the zero-based index of the item before the first item to be searched. When the search reaches the bottom of the list box, it continues from the top of the list box back to the item specified by the indexStart parameter. If indexStart is 1, the entire list box is searched from the beginning.

Windows 95: The wParam parameter is limited to 16-bit values. This means list boxes cannot contain more than 32,767 items. Although the number of items is restricted, the total size in bytes of the items in a listbox is limited only by available memory.

lpszFind

Value of lParam. Points to the null-terminated string that contains the prefix to search for. The search is case independent, so this string can contain any combination of uppercase and lowercase letters.

Return Values

The return value is the index of the matching item, or LB_ERR if the search was unsuccessful.

Remarks

If you create the list box with an owner-drawn style but without the LBS_HASSTRINGS style, this message returns the index of the item with a long value (supplied as the lParam parameter of the LB_ADDSTRING or LB_INSERTSTRING message) that matches the value supplied as the lpszFind parameter.
