VC中在listctrl中嵌入进度条，截图如下：

其实要实现这个非常容易，以下是自绘ListCtrl的代码，首先继承CListCtrl，然后增加函数OnCustomDraw： void CProcessList::OnCustomDraw(NMHDR *pNMHDR, LRESULT *pResult) {  //draw each item.set txt color,bkcolor....  NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>(pNMHDR);    // Take the default processing unless we set this to something else below.  *pResult = CDRF_DODEFAULT;    // First thing - check the draw stage. If it’s the control’s prepaint  // stage, then tell Windows we want messages for every item.    if (pLVCD->nmcd.dwDrawStage == CDDS_PREPAINT)  {   *pResult = CDRF_NOTIFYITEMDRAW;  }  else if (pLVCD->nmcd.dwDrawStage == CDDS_ITEMPREPAINT)  {   // This is the notification message for an item.  We’ll request   // notifications before each subitem’s prepaint stage.      *pResult = CDRF_NOTIFYSUBITEMDRAW;  }  else if (pLVCD->nmcd.dwDrawStage == (CDDS_ITEMPREPAINT | CDDS_SUBITEM))  {   // This is the prepaint stage for a subitem. Here’s where we set the   // item’s text and background colors. Our return value will tell   // Windows to draw the subitem itself, but it will use the new colors   // we set here.      int nItem = static_cast<int> (pLVCD->nmcd.dwItemSpec);   int nSubItem = pLVCD->iSubItem;      if(nSubItem != 2)//这里我只重绘第二列    return;

  COLORREF crText  = ::GetSysColor(COLOR_WINDOWFRAME);   COLORREF crBkgnd = ::GetSysColor(COLOR_WINDOW);      CDC* pDC = CDC::FromHandle(pLVCD->nmcd.hdc);   CRect rect;   GetSubItemRect(nItem, nSubItem, LVIR_BOUNDS, rect);   if (GetItemState(nItem, LVIS_SELECTED))    DrawText(nItem, nSubItem, pDC, ::GetSysColor(COLOR_HIGHLIGHT),     ::GetSysColor(COLOR_HIGHLIGHT), rect);   else    DrawText(nItem, nSubItem, pDC, crText, crBkgnd, rect);

  *pResult = CDRF_SKIPDEFAULT; // We’ve painted everything.  } }

然后为该函数增加消息映射(#add 其实是消息反射)： ON_NOTIFY_REFLECT(NM_CUSTOMDRAW, OnCustomDraw) 最后我们为画进度条而努力，这里程序中把进度存在ItemData中。 void CProcessList::DrawText(int nItem,          int nSubItem,          CDC *pDC,          COLORREF crText,          COLORREF crBkgnd,          CRect &rect) {  ASSERT(pDC);  pDC->FillSolidRect(&rect, crBkgnd);    int nProcess = GetItemData(nItem);  CRect procRect = rect;  pDC->Rectangle(procRect);

 procRect.left += 1;  procRect.bottom -= 1;  procRect.top += 1;  procRect.right = procRect.left + rect.Width() * nProcess / 100;  CBrush brush(RGB(255,0,0));  pDC->FillRect(&procRect, &brush);    CString str;  str.Format("%d%%", nProcess);    if (!str.IsEmpty())  {   UINT nFormat = DT_VCENTER | DT_SINGLELINE | DT_CENTER;      pDC->SetBkMode(TRANSPARENT);   pDC->SetTextColor(crText);   pDC->SetBkColor(crBkgnd);   pDC->DrawText(str, &rect, nFormat);  } }

上面用到一个结构，是存放于ItemData中用来表示进度和步长的： typedef struct _ProcessLCI_Data_ {             int  nProportion;            int  nStep; } PLCIDATA, *LPPLCIDATA;

接下来就是在容器中使用继承的ListCtrl了，这里使用对话框，在一个定时器中模拟进度的变化（其它的初始化和清除就不罗嗦了）：

void CListCtrlProcessDlg::OnTimer(UINT nIDEvent) {       if(nIDEvent == TIMER_PROCESS)       {                     BOOL bPaint = FALSE;          for(int i = 0; i < m_listProcess.GetItemCount(); ++i)           {                      LPPLCIDATA pIData = (LPPLCIDATA)m_listProcess.GetItemData(i);                      if(pIData->nProportion >= 100)                               continue;                      bPaint = TRUE;                      if(pIData->nProportion + pIData->nStep > 100)                      {                                pIData->nProportion = 100;                      }                      else                      {                                pIData->nProportion += pIData->nStep;                      }            }            if(bPaint)                      m_listProcess.Invalidate(FALSE);      }      CDialog::OnTimer(nIDEvent); }

   这里有个奇怪的问题，在VC6中不调上面的Invalidate()，只要TIMMER发生，进度条都会自动刷新。但在VC71上编译，如果不调Invalidate()，根本不刷新？？？不解！！！    从运行的结果看，效果还不错。VC6编译的就是满100%后进度条还是不停的闪烁；而VC71就不会了，因为没有调Invalidate()？？？

怎么样？很简单吧，其实使用VC开发界面也非常迅速的，虽然还是觉得MFC的封装有JAVA界面库封装得那么好该多好啊
