防止CListCtrl闪烁的几种方法

1. 使用SetRedraw禁止窗口重绘,操作完成后,再恢复窗口重绘

m_ctlList.SetRedraw(FALSE);
//以下为更新数据操作
//……
//恢复窗口重绘
m_ctlList.SetRedraw(TRUE);

2. 使用LockWindowUpdate禁止窗口重绘，操作完成后，用UnlockWindowUpdate恢复窗口重绘

m_ctlList.LockWindowUpdate();
//以下为更新数据操作
//……
//恢复窗口重绘
m_ctlList.UnlockWindowUpdate();

3. 使用ListCtrl的内部双缓冲（经实测, 好像不起作用）

m_ctlLisit.SetExtendedStyle(m_ctlLisit.GetExtendedStyle()|LVS_EX_DOUBLEBUFFER);
VC6未定义LVS_EX_DOUBLEBUFFER宏，使用者可以自定义，如下：
#define LVS_EX_DOUBLEBUFFER 0×00010000

4. Virtual List

首先要设置ListCtrl风格为LVS_REPORT | LVS_OWNERDATA或在ListCtrl属里中的More Styles页面中选中Owner data复选框。
其次要向应LVN_GETDISPINFO消息；
void OnGetdispinfoList(NMHDR* pNMHDR, LRESULT* pResult)
{
	LV_DISPINFO* pDispInfo = (LV_DISPINFO*)pNMHDR;
	LV_ITEM *pItem = &(pDispInfo)->item;
	char szText[128] = {0};
	
	if (pItem->mask & LVIF_TEXT)
	{
		//使缓冲区数据与表格子项对应
		//m_ArrayBuff为二维数组
		//定义如下 int m_ArrayBuff[2048][4];
		_stprintf(szText,_T(“%d”),m_ArrayBuff[pItem->iItem][pItem->iSubItem]);
		pItem->pszText = szText;
	}
	
	*pResult = 0;
	}
	
	最后便是生成缓冲区数据
	void Insertdata()
	{
		//删除之前的数据
		m_ctlList.SetItemCountEx(0);
		m_ctlList.Invalidate();
		m_ctlList.UpdateWindow();
		srand( (unsigned)time( NULL ));
		
		//生成新的数据缓冲区
		int nItemCount = 2048;
		for (int i = 0;i < nItemCount; i ++)
		{
		for (int k = 0;k < 4;k ++)
		{
			m_ArrayBuff[i][k] = rand()%2048 + 1;
		}
	}
	
	if (nItemCount < 2)
	{
		m_ctlList.SetItemCountEx(1);
	}
	else
	{
		m_ctlList.SetItemCountEx(nItemCount);
	}
	
	m_ctlList.Invalidate();
}
若要修改数据，只要修改缓冲区m_ArrayBuff的数据即可以

5.  自绘（最常用，最简单）

首先当然是重载CListCtrl类，设置ListCtrl属性"Owner Draw Fixed"为true,"Owner data"为false

(1).  并接管WM_ERASEBKGND消息，去掉默认的处理，改为不处理

手动添加重载消息ON_WM_ERASEBKGND()

BOOL CListCtrlEx::OnEraseBkgnd(CDC* pDC)
{
//响应WM_ERASEBKGND消息
return false;
//屏蔽默认处理
//return CListCtrl::OnEraseBkgnd(pDC);
}

(2). 手动添加重载消息ON_WM_DRAWITEM()

void CListCtrlEx::OnPaint()
{
//响应WM_PAINT消息
CPaintDC dc(this); // device context for painting
CRect rect;
CRect headerRect;
CDC MenDC;//内存ID表
CBitmap MemMap;
GetClientRect(&rect);
GetDlgItem(0)->GetWindowRect(&headerRect);
MenDC.CreateCompatibleDC(&dc);
MemMap.CreateCompatibleBitmap(&dc,rect.Width(),rect.Height());
MenDC.SelectObject(&MemMap);
MenDC.FillSolidRect(&rect,RGB(228,236,243));
//这一句是调用默认的OnPaint(),把图形画在内存DC表上
DefWindowProc(WM_PAINT,(WPARAM)MenDC.m_hDC,(LPARAM)0);
//输出
dc.BitBlt(0,headerRect.Height(),rect.Width(), rect.Height(),&MenDC,0, headerRect.Height(),SRCCOPY);
MenDC.DeleteDC();
MemMap.DeleteObject();
}

(3). 手动添加重载消息ON_WM_MEASUREITEM_REFLECT()

void DrawItem(_In_ LPDRAWITEMSTRUCT lpDrawItemStruct);

例如：这是我自己的的代码，可能你们有些符号找不到，这方面有疑问的话，可以咨询我QQ173708459，大家共同探讨

void CMyListCtrl::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
	CDC* pDC = CDC::FromHandle(lpDrawItemStruct->hDC);
	LVITEM lvi = { 0 };
	lvi.mask = LVIF_STATE | LVIF_IMAGE; 
	lvi.stateMask = LVIS_FOCUSED | LVIS_SELECTED;
	lvi.iItem = lpDrawItemStruct->itemID; //表示菜单项ID,也可以表示列表框或者组合框中某项的索引值
	BOOL bGet = GetItem(&lvi); //获取某些或全部列表视图项的属性


	//颜色变量
	COLORREF cTextColor;
	COLORREF cBackColor;

	//绘制区域
	CRect rcBack = lpDrawItemStruct->rcItem;
	int nWidth = rcBack.Width();
	int nHeight = rcBack.Height();

	//偏移图标位置(44*44),避免选中行时图标也被选中
	rcBack.left += 48;
	pDC->SetBkMode(TRANSPARENT);

	//统一字体
	CFont* OldFont = (CFont*)pDC->SelectObject(m_Font); //预先设置文本字体

	//判断是否选中
	BOOL bHighlight = ((lvi.state & LVIS_DROPHILITED) || ((lvi.state & LVIS_SELECTED) && ((GetFocus() == this) || (GetStyle() & LVS_SHOWSELALWAYS))));

	//(1).先设置文本及背景色 
	if (bHighlight) //选中行
	{
		cTextColor = m_SelectItemTextColor;
		cBackColor = m_SelectItemBackColor;
	}
	else if (lvi.iItem == m_nHoverIndex) //热点行
	{
		cTextColor = m_HoverItemTextColor;
		cBackColor = m_HoverItemBackColor;
	}
	else
	{
		if (lpDrawItemStruct->itemID % 2) //奇数行
		{
			cTextColor = m_OddItemTextColor;
			cBackColor = m_OddItemBackColor;
		}
		else //偶数行
		{
			cTextColor = m_EvenItemTextColor;
			cBackColor = m_EvenItemBackColor;
		}
	}

	//(2).再统一绘制颜色
	pDC->SetTextColor(cTextColor);
	pDC->FillRect(rcBack, &CBrush(cBackColor));

	//(3).绘制文本内容
	if (lpDrawItemStruct->itemAction & ODA_DRAWENTIRE)
	{
		//获取列数
		CString szText;
		int nCollumn = GetHeaderCtrl()->GetItemCount();

		//循环得到文本 
		for (int i = 0; i < nCollumn; i++)
		{ 
			//获取子项矩形边界 
			CRect rcItem;
			if (!GetSubItemRect(lvi.iItem, i, LVIR_LABEL, rcItem))
			{
				continue;
			}

			//获取子项文本内容
			szText = GetItemText(lvi.iItem, i);

			//绘制按钮
			if (m_nListMark == LIST_INSTALL)
			{
				strTask_S *pTask = (strTask_S*)lpDrawItemStruct->itemData;
				if (NULL != pTask)
				{

							//pDC->RoundRect(&rect, point);
							pDC->Rectangle(rect);
							pDC->SelectObject(hOldPen);
							hNewPen.DeleteObject();

							//填充颜色
							rect.top += 1;

							OutputDebugString(sInfo);

							rect.right = rect.left + nLen;
							CBrush brush(RGB(31, 210, 69));
							pDC->FillRect(&rect, &brush);
							//brush.DeleteObject();

							//绘制文本
							CRect rcText(pTask->strProgress.rect);
							rcText.top = rcText.bottom + 8;
							rcText.bottom = rcText.top + 13;
