Searches the list box of a combo box for an item beginning with the characters in a specified string.
The zero-based index of the item preceding 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 wParam parameter. If wParam is –1, the entire list box is searched from the beginning.
A pointer to the null-terminated string that contains the characters for which to search. The search is not case sensitive, so this string can contain any combination of uppercase and lowercase letters.
The return value is the zero-based index of the matching item. If the search is unsuccessful, it is CB_ERR.
If you create the combo box with an owner-drawn style but without the CBS_HASSTRINGS style, what the CB_FINDSTRING message does depends on whether your application uses the CBS_SORT style. If you use the CBS_SORT style, WM_COMPAREITEM messages are sent to the owner of the combo box to determine which item matches the specified string. If you do not use the CBS_SORT style, the CB_FINDSTRING message searches for a list item that matches the value of the lParam parameter.
