用客户区的一块区域做标题栏可能会更容易一些～

/****************************************************************************
主要思路是在处理主窗口的WM_WINDOWPOSCHANGED消息，并让指定窗口移动。
此方法可扩展应用到需要窗口跟随的很多场景中

win10 + vs2008 编译通过
代码仅供参考！

推荐无边框窗口，然后自绘标题栏， 就可以放置任意控件

[oblivi]

这些一般不是控件，只是画上去的，判断鼠标是否在它的RECT中，再处理消息就可以了

[schlafenhamster]

即 OnNcHitTest(CPoint point)

有代码吗，最好是工程文件 。多谢
