我的日期在选择时不会改变 [英] My Date does not change on selection

问题描述

您好，



我正在尝试扩展这个 [ ^ ]在列表控件中考虑日期。

我的源代码如下。 cpp文件，我从CDateTimeCtrl类派生我的类，但由于某种原因我的日期不会改变选择。关于我哪里出错的任何建议？



我的.cpp文件 ：

Hello,

I am trying to extend this[^] to take into account dates as well in the list control.
I have the following source code in my .cpp file whereby I have derived my class from the CDateTimeCtrl class but for some reason my date does not change on selection. Any suggestions on where I am going wrong?

My .cpp file:

CInPlaceDateCtrl* CInPlaceDateCtrl::m_pInPlaceDate = NULL;

CInPlaceDateCtrl::CInPlaceDateCtrl(void)
{
   m_iRowIndex= -1;
	m_iColumnIndex = -1;
	m_bESC = FALSE;
	m_strValidChars.Empty();
}

{
}

CInPlaceDateCtrl* CInPlaceDateCtrl::GetInstance()
{
	if(m_pInPlaceDate == NULL)
	{
		m_pInPlaceDate = new CInPlaceDateCtrl();
	}
	return m_pInPlaceDate;
}

	delete m_pInPlaceDate;
	m_pInPlaceDate = NULL;
}

{
	m_iRowIndex = iRowIndex;
	m_iColumnIndex = iColumnIndex;
	m_strWindowText = rstrCurSelection;
	m_bESC = FALSE;

	if (NULL == m_pInPlaceDate->m_hWnd) 
	{
		BOOL result = m_pInPlaceDate->Create(dwStyle, rCellRect, pParentWnd, uiResourceID);

      m_pInPlaceDate->SetMonthCalColor(MCSC_TITLEBK, RGB(0, 0, 128));
      m_pInPlaceDate->SetMonthCalColor(MCSC_MONTHBK, RGB(70, 170, 255));
	   m_pInPlaceDate->SetMonthCalColor(MCSC_TEXT, RGB(250, 240, 50));
	   m_pInPlaceDate->SetMonthCalColor(MCSC_TITLETEXT, RGB(255, 255, 0));
	   m_pInPlaceDate->SetMonthCalColor(MCSC_BACKGROUND, RGB(190, 225, 240));
	   m_pInPlaceDate->SetMonthCalColor(MCSC_TRAILINGTEXT, RGB(150, 200, 255));

      m_pInPlaceDate->SetFormat(_T("dd/MM/yy"));
