CMonthCalCtrl::SetFirstDayOfWeek

Visual Studio 2010

Sets the day of week to be displayed in the leftmost column of the calendar.

BOOL SetFirstDayOfWeek(
   int iDay,
   int* lpnOld = NULL 
);

Parameters

iDay: An integer value representing which day is to be set as the first day of the week. This value must be one of the day numbers. See GetFirstDayOfWeek for a description of the day numbers.
lpnOld: A pointer to an integer indicating the first day of the week previously set.

Return Value

Nonzero if the previous first day of the week is set to a value other than that of LOCALE_IFIRSTDAYOFWEEK, which is the day indicated in the control panel setting. Otherwise, this function returns 0.

Remarks

This member function implements the behavior of the Win32 message MCM_SETFIRSTDAYOFWEEK, as described in the Windows SDK.

Example

C++


// This work isn't normally necessary, since the control will set 
// the day of the week to match the system locale by itself.

// Ask the system for the first day of the week
TCHAR sz[2];
GetLocaleInfo(LOCALE_SYSTEM_DEFAULT, LOCALE_IFIRSTDAYOFWEEK, sz, 2);

// Convert from string result
int nFirstDay = _ttoi(sz);

// Set it and assert that it was successful.
m_calCtrl1.SetFirstDayOfWeek(nFirstDay);
ASSERT(m_calCtrl1.GetFirstDayOfWeek() == nFirstDay);
