Syntax
LB_SELECTSTRING wParam = (WPARAM) indexStart;
lParam = (LPARAM)(LPCTSTR) lpszFind;
Parameters
indexStart
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 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.
lpszFind
Long pointer 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 index of the selected item indicates a successful search. LB_ERR indicates an unsuccessful search; the current selection is not changed.
Remarks
The list box is scrolled, if necessary, to bring the selected item into view.
Do not use this message with a list box that has the LBS_MULTIPLESEL style.
An item is selected only if its initial characters from the starting point match the characters in the string specified by the lpszFind parameter.
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 whose long value (supplied as the lParam parameter of the LB_ADDSTRING or LB_INSERTSTRING message) matches the value supplied as the lParam parameter of LB_SELECTSTRING.
