1、CListCtrl自定义控件的列分割栏拖动
   项目中自定义一个可编辑子项目的CListCtrl控件，因为需要在拖动列分割栏时取消编辑状态，所以
定义了一个HDN_BEGINTRACK事件，发现拖动后会留下一条竖线，于是GOOGLE，一篇英文文章上提供了解
决方法，其实很简单，就是只需在重载的OnNotify事件内处理就行了，例子如下：
BOOL CEditListCtrl::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
 LPNMHDR pNMHDR = (LPNMHDR)lParam;
 if(pNMHDR->code == HDN_BEGINTRACKA || pNMHDR->code == HDN_BEGINTRACKW || pNMHDR-
>code == NM_CLICK){
  //LPNMHEADER phdr = reinterpret_cast<LPNMHEADER>(pNMHDR);
  CancelEdit(); //取消编辑状态
 }
 return CListCtrl::OnNotify(wParam, lParam, pResult);
}

2、自定义控件的字体
  SetFont参数的字体变量需是程序运行时候一直存在的变量，不可以是局部变量，否则不能更改自定义控件的字体格式。
 
3、加载指定尺寸的图标
  如下面的例子是加载16×16的资源ID为IDI_ADD的图标
  (HICON)::LoadImage(AfxGetApp()->m_hInstance, MAKEINTRESOURCE(IDI_ADD), IMAGE_ICON, 16, 16, LR_SHARED);
 
4、关于DestroyWindow
  当CreateWindow了一个子窗口，包括使用CDialog::Create创建一个WS_CHILD风格的对话框，父窗口终
止时候不需要显示调用子窗口的DestroyWindow；但是若子窗口申请了内存，则需要重载子窗口的
DestroyWindow函数释放内存，且需要在父窗口终止时显示调用子窗口的DestroyWindow。
 
5、发送WM_LBUTTONDOWN消息
  发送WM_LBUTTONDOWN消息模拟鼠标按下，不能使用SendMessage，而应使用PostMessage，原因暂无时间了解。
 
6、关于宏定义中的字符连接
  当一个宏定义语句定义了一个字符串，其中需用到或者说连接其他宏定义的字符串，那么这时需使用双井号，如下例子：
  #define LOCALDB_TABLENAME      "mt_flux"
  #define LOCALDB_FN_UPLOADFLAG    "uploadflag"
  #define LOCALDB_FN_FLUXNO      "fluxno"
  #define LOCALDB_SETUPLOAD_SQL \
 "UPDATE "##LOCALDB_TABLENAME" SET "##LOCALDB_FN_UPLOADFLAG "=1 WHERE "##LOCALDB_FN_FLUXNO"=?"
 
7、LogFont与CharFormat互相转换(来源：http://blog.csdn.net/carl2380/article/details/3237391)
way1:
    CFontDialog::getcharformat
way2:
void CTextLine::ChangeLogFontToCharFormat(CHARFORMAT &cf, const LOGFONT lf, const COLORREF textcolor)
{
//CFE_AUTOCOLOR
 cf.dwMask = CFM_BOLD|CFM_CHARSET|CFM_COLOR|CFM_FACE|CFM_ITALIC|/
    CFM_SIZE|CFM_UNDERLINE|CFM_STRIKEOUT;
 
 BOOL bIsItalic = lf.lfItalic ;
 BOOL bIsBold = (lf.lfWeight > FW_BOLD);//? FW_NORMAL:FW_BOLD;
 BOOL bIsUnderline = lf.lfUnderline ;
 BOOL bIsStrickout = lf.lfStrikeOut ;
 cf.dwEffects |= CFE_PROTECTED;
 cf.dwEffects &= ~CFE_AUTOCOLOR;
 if (bIsBold)
  cf.dwEffects |= CFE_BOLD;
 else
  cf.dwEffects &= ~CFE_BOLD; 
 if (bIsItalic)
  cf.dwEffects |= CFE_ITALIC;
 else
  cf.dwEffects &= ~CFE_ITALIC;
 
 if (bIsUnderline)
  cf.dwEffects |= CFE_UNDERLINE;
 else
  cf.dwEffects &= ~CFE_UNDERLINE; 
 if (bIsStrickout)
  cf.dwEffects |= CFM_STRIKEOUT;
 else
  cf.dwEffects &= ~CFM_STRIKEOUT;
 
 //设置属性
 cf.yHeight =  -15 * lf.lfHeight;
 cf.crTextColor = textcolor;//;//m_Font_Color;
 cf.bCharSet = lf.lfCharSet ;
 cf.bPitchAndFamily = lf.lfPitchAndFamily ;
 sprintf(cf.szFaceName, lf.lfFaceName);
}
void CTextLine::ChangeCharFormatToLogFont(CHARFORMAT cf,  LOGFONT &lf,  COLORREF &textcolor)
{
 lf.lfOutPrecision = 3;
 lf.lfClipPrecision =2;
 lf.lfQuality = 1;
 //粗体
 if ((cf.dwEffects &CFE_BOLD )>0)
  lf.lfWeight = 700;
 else
  lf.lfWeight = 400;
 //斜体
 if ((cf.dwEffects &CFE_ITALIC)>0)
  lf.lfItalic = 1;
 else
  lf.lfItalic = 0;

 //下划线
 if ((cf.dwEffects & CFE_UNDERLINE)>0)
  lf.lfUnderline = 1;
 else
  lf.lfUnderline = 0;
 //删除线
 if ((cf.dwEffects & CFE_STRIKEOUT)>0)
  lf.lfStrikeOut = 1;
 else
  lf.lfStrikeOut =0;
 
 lf.lfHeight = (-cf.yHeight/15);
 textcolor = cf.crTextColor;
 lf.lfCharSet = cf.bCharSet;
 lf.lfPitchAndFamily = cf.bPitchAndFamily;
 sprintf(lf.lfFaceName, cf.szFaceName);}
