An application sends an LB_GETLOCALE message to retrieve the current locale of the list box. You can use the locale to determine the correct sorting order of displayed text (for list boxes with the LBS_SORT style) and of text added by the LB_ADDSTRING message.
LB_GETLOCALE
wParam = 0; // not used; must be zero
lParam = 0; // not used; must be zero
Parameters
This message has no parameters.
Return Values
The return value is a 32-bit value that specifies the current locale of the list box. The high-order word contains the country code and the low-order word contains the language identifier.
Remarks
The language identifier consists of a sublanguage identifier and a primary language identifier. Use the PRIMARYLANGID macro to extract the primary language identifier from the low-order word of the return value, and the SUBLANGID macro to extract the sublanguage identifier.
