CB_SETLOCALE message

An application sends a CB_SETLOCALE message to set the current locale of the combo box. If the combo box has the CBS_SORT style and strings are added using CB_ADDSTRING, the locale of a combo box affects how list items are sorted.

Parameters

wParam

Specifies the locale identifier for the combo box to use for sorting when adding text.

lParam

This parameter is not used.

Return value

The return value is the previous locale identifier. If wParam specifies a locale not installed on the system, the return value is CB_ERR and the current combo box locale is not changed.

Remarks

Use the MAKELCID macro to construct a locale identifier and the MAKELANGID macro to construct a language identifier. The language identifier is made up of a primary language identifier and a sublanguage identifier.
