标签：lf MFC 对象 SelectObject 选择对象 hdc 句柄
HDC hdc = ::GetDC(m_hWnd);
LOGFONT lf = { 0 };
lf.lfWeight = 16; //平均宽度
lf.lfHeight = 40;//字体高度
lf.lfCharSet = GB2312_CHARSET;
HFONT hfont = ::CreateFontIndirect(&lf);
HFONT holdfont= (HFONT)SelectObject(hdc, hfont);//新对象替换相同类型的对象
/*
参数1：HDC hdc DC句柄
参数2：HGDIOBJ hgdiobj 新对象
但该对象的句柄必须使用以下函数创建才有效：
Bitmap(位图) CreateBitmap, CreateBitmapIndirect,
CreateCompatibleBitmap, CreateDIBitmap,
CreateDIBSection
Brush(画刷) CreateBrushIndirect, eateDIBPatternBrush,
CreateDIBPatternBrushPt, CreateHatchBrush,
CreatePatternBrush, CreateSolidBrush
Font(字体) CreateFont, CreateFontIndirect
Pen(画笔) CreatePen, CreatePenIndirect
Region(区域) CombineRgn, CreateEllipticRgn,
CreateEllipticRgnIndirect,
CreatePolygonRgn, CreateRectRgn,
CreateRectRgnIndirect
返回值：HGDIOBJ 如果选择对象不是区域并且函数执行成功，那么返回值是被取代的对象的句柄
如果选择对象是区域并且函数执行成功，返回如下一值
如果发生错误并且选择对象不是一个区域，那么返回值为NULL，否则返回HGDI_ERROR
