话不多说，先验货：
（原始状态）
（最大化状态）
（对比图）
为自己鼓掌！！！
哈哈，捣鼓2天终于把这个搞出来了！虽然代码一团糟，但是不难理解！
要实现这个功能需要几个组件：DWM，GDI+
在实现这个代码中我认为最困难的就是chrome边框的阴影部分~
（这里的2个像素的阴影）
和本身客户区边框的1个黑色像素，这1个像素IE11没有处理，而CHROME却没有这个黑边：
最开始使用GDI，但是GDI不带有Alpha通道，导致在画阴影时画出来的是实线，所以换成GDI+，下面是实现效果（没有采用圆角矩形，因为GDI+没有直接绘制圆角矩形的接口）：
好了，上代码：
1 # include <windows.h>
2 #include <windowsx.h>
3 # include <stdio.h>
4 # include <stdlib.h>
5 #include "dwmapi.h"
6 #include "resource.h"
7 #include <gdiplus.h>
8 using namespace Gdiplus;
