LB_FINDSTRINGEXACT Overview Group

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 
 

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 to search for. This string can contain a complete filename, including the extension. The search is not case sensitive, so this string can contain any combination of uppercase and lowercase letters.

Return Values

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

Remarks

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.
