// 首先必须保证你的strTime是 unicode 宽字符的，如果不是转换为宽字符。

// 使用OLE函数。
DATE dtResult;
HRESULT hr= VarDateFromStr( strTime, GetSystemDefaultLCID(), 0, &dtResult);

// m_theDateTimePicker;
m_theDateTimePicker.SetTime( COleDateTime(dtResult) );

SetTime Sets the time in a date and time picker control.
MSDN中可以查到
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 COleDateTime object containing the to which the control will be set.

pTimeNew

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

Remarks

This member function implements the behavior of the Win32 messageDTM_SETSYSTEMTIME, 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.
