Handle to a combo box control
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
Specifies the zero-based index of the item preceding the first item to be searched. When the search reaches the bottom of the list, it continues from the top of the list back to the item specified by the $start_idx parameter. If $start_idx is -1, the entire list is searched from the beginning.
Search the list of a combo box for an item that begins with the characters in a specified string. If a matching item is found, it is selected and copied to the edit control. It is a wrapper around sending CB_SELECTSTRING message. In contrary to SelComboItemText this function causes combo box to send CBN_SELCHANGE notification.
