An application sends a CB_GETLOCALE message to retrieve the current locale of the combo box. The locale is used to determine the correct sorting order of displayed text for combo boxes with the CBS_SORT style and text added by using the CB_ADDSTRING message.
CB_GETLOCALE
wParam = 0; // not used; must be zero

Parameters

Return Values
The return value is a 32-bit value that specifies the current locale of the combo box. The high word contains the country code and the low-order word contains the language identifier.
Remarks
The language identifier is made up of a sublanguage identifier and a primary language identifier. The PRIMARYLANGID macro obtains the primary language identifier and the SUBLANGID macro obtains the sublanguage identifier.
