Return Value

Returns a DWORD value that contains two values. The high-order word is a BOOL that is nonzero if the previous first day of the week did not equal LOCALE_IFIRSTDAYOFWEEK, or zero otherwise. The low-order word is an INT value that represents the previous day of the week number (see list under iDay).

Remarks

If the first day of the week is set to anything other than the default (LOCALE_IFIRSTDAYOFWEEK), the control will not automatically update first-day-of-the-week changes based on locale changes.
