int FindString( int nStartAfter, const char FAR* lpItem ) const;
nStartAfter
Contains 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 nStartAfter. If nStartAfter is -1, the entire list box is searched from the beginning.
lpItem
Points to the null-terminated string that contains the prefix to search for. The search is case-independent, so this string may contain any combination of uppercase and lowercase letters.
Finds the first string in a list box that contains the specified prefix without changing the list-box selection. Use the SelectString member function to both find and select a string.
The zero-based index of the matching item, or LB_ERR if the search was unsuccessful.
