Syntax
CB_FINDSTRINGEXACT wParam = (WPARAM) indexStart,
lParam = (LPARAM)(LPCSTR) lpszFind
Parameters
indexStart
Specifies 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 indexStart parameter. If indexStart is –1, the entire list box is searched from the beginning.
lpszFind
Long pointer 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 zero-based index of the matching item indicates success. CB_ERR indicates an unsuccessful search.
Remarks
This message does not work across processes. You can not make the call SendMessage(CB_FINDSTRINGEXACT) to another process.
If you create the combo box with an owner-drawn style but without the CBS_HASSTRINGS style, what the CB_FINDSTRINGEXACT 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_FINDSTRINGEXACT message searches for a list item that matches the value of the lpszFind parameter.
