An application sends a LB_FINDSTRINGEXACT message to find the first list box string that matches the string specified in the lpszFind parameter.
LB_FINDSTRINGEXACT
wParam = (WPARAM) indexStart; // item before start of search
lParam = (LPARAM)(LPCSTR)lpszFind; // address of search string
Windows 95 and Windows 98: 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 list box is limited only by available memory.
The return value is the zero-based index of the matching item, or LB_ERR if the search was unsuccessful.
If an application creates the list box with an owner-drawn style but without the LBS_HASSTRINGS style, the action taken by LB_FINDSTRINGEXACT depends on whether the LBS_SORT style is used. If LBS_SORT is used, the system sends WM_COMPAREITEM messages to the list box owner to determine which item matches the specified string. Otherwise, LB_FINDSTRINGEXACT attempts to match the 32-bit value against the value of the lpszFind parameter.
