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();
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
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();
}void DrawItem(_In_ LPDRAWITEMSTRUCT lpDrawItemStruct);
