分享CEdit用了一个垂直居中的类后，怎么边框没法改变？
最终效果要垂直左右都居中，失去和获得焦点改变边框及背景颜色。贴代码：
用了几个网上的垂直代码，垂直居中解决了，但OnSetFocus及OnNcPaint中改变边框却没效果了，谁遇到过？

按你的方法是可以的。但这个类GDI资源泄漏很严重，感觉没用到几个gdi对象，我不知道问题出来哪里？

我只试了一下，在OnSetFocus及OnNcPaint中画过，可是没效果

你这个控件重绘过
是不是没有绘制相应的状态

用的就是你的程序.
focus 是在 OnPaint 中画, 你那个红框是在 NcPaint 中画的, 不行的

你说的这个我知道，我调用了OnNcCalcSize这个消息处理垂直居中，然后不管在哪里画边框都没有作用。

边框颜色的绘制你需要放在

你的这个截图好像是垂直居中，是怎么做的？那个红色边框能不能放大，和Edit框一样大小，鼠标移进移出（或获取焦点失去焦点）有不同效果。

CRect rect;
GetClientRect(rect);
// rect.InflateRect(1,3,3,1); ???
rect.InflateRect(1,1);
// red border
pDC ->FrameRect(rect,&m_BkBrush2);

"怎么边框没法改变"
是指 BORDER?
