这个例子不错,可以得到时间的三种设置方法.

 

CDateTimeCtrl::SetTime

BOOL SetTime( const COleDateTime& timeNew );

BOOL SetTime( const CTime* pTimeNew );

BOOL SetTime( LPSYSTEMTIME pTimeNew = NULL );

Return Value

Nonzero if successful; otherwise 0.

Parameters

timeNew

A reference to a object containing the to which the control will be set.

pTimeNew

In the second version above, a pointer to a object containing the time to which the control will be set. In the third version above, a pointer to a structure containing the time to which the control will be set.

Remarks

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

In the MFC implementation of SetTime, you can use the COleDateTime or CTime classes, or you can use a SYSTEMTIME structure, to set the time information.

Example

void CDatesDlg::OnButton2() 
{
   // Gain a pointer to the control
   // CMonthCalCtrl* pCtrl = (CMonthCalCtrl*) GetDlgItem(IDC_MONTHCALENDAR1);
   CDateTimeCtrl* pCtrl = (CDateTimeCtrl*) GetDlgItem(IDC_DATETIMEPICKER1);
   ASSERT(pCtrl != NULL);

   // set with a CTime
   CTime timeTime(1998, 4, 3, 0, 0, 0);
   VERIFY(pCtrl->SetTime(&timeTime));

   // set with a COleDateTime object
   COleDateTime oletimeTime(1998, 4, 3, 0, 0, 0);
   VERIFY(pCtrl->SetTime(oletimeTime));

   // set using the SYSTEMTIME
   SYSTEMTIME sysTime;
   memset(&sysTime, 0, sizeof(sysTime));
   sysTime.wYear = 1998;
   sysTime.wMonth = 4;
   sysTime.wDay = 3;
   VERIFY(pCtrl->SetTime(&sysTime));
}
