Sets the currently selected date for a month calendar control.
BOOL SetCurSel(
   const COleDateTime& refDateTime 
);
BOOL SetCurSel(
   const CTime& refDateTime 
);
BOOL SetCurSel(
   const LPSYSTEMTIME pDateTime 
);
Parameters
refDateTime
A reference to a COleDateTime or CTime object indicating the currently-selected month calendar control.pDateTime
Pointer to a SYSTEMTIME structure that contains the date to be set as the current selection.
Return Value
Nonzero if successful; otherwise 0.
Remarks
This member function implements the behavior of the Win32 message MCM_SETCURSEL, as described in the Windows SDK. In MFC's implementation of SetCurSel, you can specify a COleDateTime usage, a CTime usage, or a SYSTEMTIME structure usage.
Example
void CMonthCalDlg::OnBnClickedCurselbutton()
{
   // All of these calls set the current selection to March 15, 1998.
   // with a COleDateTime
   COleDateTime dt1(1998, 3, 15, 0, 0, 0);
   m_calCtrl1.SetCurSel(dt1);
   // with a CTime
   CTime dt2(1998, 3, 15, 0, 0, 0);
   m_calCtrl1.SetCurSel(dt2);
   // with a SYSTEMTIME structure
   SYSTEMTIME sysTime;
   // set everything to zero
   memset(&sysTime, 0, sizeof(sysTime));
   // except for the date we want
   sysTime.wYear = 1998;
   sysTime.wMonth = 3;
   sysTime.wDay = 15;
   m_calCtrl1.SetCurSel(&sysTime);
}
