Windows 介面：OnCustomDraw 設定 CListCtrol 任意行的文本字型顏色以及背景色

1，首先使用 ClassWizard 建立一個 CListCtrl 的衍生類別，在它的標頭檔訊息響應函數中添加：

 // Generated message map functions
protected:
 //{{AFX_MSG(CScanFileList) //}}AFX_MSG
 afx_msg void OnCustomDraw(NMHDR* pNMHDR, LRESULT* pResult);

 DECLARE_MESSAGE_MAP() 

2，相應的，類實現檔案添加：

BEGIN_MESSAGE_MAP(CScanFileList, CListCtrlEx)
 //{{AFX_MSG_MAP(CScanFileList)
 ...
 ON_NOTIFY_REFLECT(NM_CUSTOMDRAW, OnCustomDraw)
 ...
 //}}AFX_MSG_MAP
END_MESSAGE_MAP()

3，函數實現：

void CScanFileList::OnCustomDraw ( NMHDR* pNMHDR, LRESULT* pResult )
{
 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 ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
 {
        *pResult = CDRF_NOTIFYITEMDRAW;
 }
    else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
 {

// 這裡僅僅比較文本，注意：index == pLVCD->nmcd.dwItemSpec
  if (GetItemText(pLVCD->nmcd.dwItemSpec, 2) == m_lpszEncrypt)
  {
   pLVCD->clrText = RGB(255,0,0);
   pLVCD->clrTextBk = RGB(255,0,0);
  }

         // Tell Windows to paint the control itself.
        *pResult = CDRF_DODEFAULT;
 }
}
